Abstract
Molecular immobilization and recognition are two key events for the development of biosensors. The general ways for the immobilization and recognition of biomolecules include covalent coupling reactions and non-covalent interactions of antigen-antibody, aptamer-target, glycan-lectin, avidin-biotin and boronic acid-diol. Tetradentate nitrilotriacetic acid (NTA) is one of the most common commercial ligands for chelating metal ions. The NTA-metal complexes show high and specific affinity toward hexahistidine tags. Such metal complexes have been widely utilized in protein separation and immobilization for diagnostic applications since most of commercialized proteins have been integrated with hexahistidine tags by synthetic or recombinant techniques. This review focused on the development of biosensors with NTA-metal complexes as the binding units, mainly including surface plasmon resonance, electrochemistry, fluorescence, colorimetry, surface-enhanced Raman scattering spectroscopy, chemiluminescence and so on.

Abstract
The present study reports on the synthesis of a new alkoxysilane-bearing light-responsive cinnamyl group and its application as a surface functionalization agent for the development of SiO2 nanoparticles (NPs) with photoreversible tails. In detail, cinnamic acid (CINN) was activated with N-hydroxysuccinimide (NHS) to obtain the corresponding NHS-ester (CINN-NHS). Subsequently, the amine group of 3-aminopropyltriethoxysilane (APTES) was acylated with CINN-NHS leading to the generation of a novel organosilane, CINN-APTES, which was then exploited for decorating SiO2 NPs. The covalent bond to the silica surface was confirmed by solid state NMR, whereas thermogravimetric analysis unveiled a functionalization degree much higher compared to that achieved by a conventional double-step post-grafting procedure. In light of these intriguing results, the strategy was successfully extended to naturally occurring sepiolite fibers, widely employed as fillers in technological applications. Finally, a preliminary proof of concept of the photoreversibility of the obtained SiO2@CINN-APTES system has been carried out through UV diffuse reflectance. The overall outcomes prove the consistency and the versatility of the methodological protocol adopted, which appears promising for the design of hybrid NPs to be employed as building blocks for photoresponsive materials with the ability to change their molecular structure and subsequent properties when exposed to different light stimuli.

Abstract
Telomerase, a special ribonucleoprotein reverse transcriptase, can maintain the length and stability of telomeres and plays an important role in cell proliferation and differentiation. Due to the distinguishable expression level in normal cells and cancer cells, telomerase has become an important biomarker for cancer diagnosis and prognosis evaluation. Despite major breakthroughs in the field of telomerase detection, the extracts in the cell lysate are still the first choice as the analyte nevertheless, which will bring serious inaccuracies compared with the real intracellular activity. With the development of nanotechnology and nanomaterials, extraordinary progress has been made in telomerase detection by employing different versatile nanoprobes. In this review, we list the superiority of nanoprobes and systematically summarize the applications of nanoprobes in telomerase detection from the aspects of various nanomaterials and discuss the current challenges and potential trends in the future design of nanoprobes.

Abstract
We have successfully prepared a highly sensitive sandwich nanosensor combined Fe3O4 and Au@ATP@Ag nanorods for histamine detection based on surface-enhanced Raman spectroscopy (SERS). The Fe3O4 beads with -COOH served as a capture part to enrich histamine. The Au@ATP@Ag core-shell nanorods functionalized with Nalpha,Nalpha-Bis(carboxymethyl)-l-lysine (AB-NTA) were then used to connect with the imidazolyl group of histamine, simultaneously the internal standard 4-aminothiophenol (4-ATP) in the core-shell structure was used as the SERS signal. PLS regression model based on concentration range 10-3-10-8mol/L showed a linear trend with R2 = 0.9907. Our new approach can quickly and reliably determine histamine in fish sample and RAW264.7 cell lysates. This protocol for histamine extraction and SERS analysis enables the development of ultra-sensitive method for histamine detection.

Abstract
Inappropriate and frequent use of antibiotics has led to the development of antibiotic-resistant bacteria, which cause infectious diseases that are difficult to treat. With the rising threat of antibiotic resistance, the need to develop effective new antimicrobial agents is prominent. We report antimicrobial metallopolymer nanoparticles, which were prepared by surface-initiated reversible addition-fragmentation chain transfer polymerization of a cobaltocenium-containing methacrylate monomer from silica nanoparticles. These particles are capable of forming a complex with β-lactam antibiotics, such as penicillin, rejuvenating the bactericidal activity of the antibiotic. Disk diffusion assays showed significantly increased antibacterial activities against both Gram-positive and Gram-negative bacteria. The improved efficiencies were attributed to the inhibition of hydrolysis of the β-lactam antibiotics and enhancement of local antibiotics concentration on a nanoparticle surface. In addition, hemolysis evaluations demonstrated minimal toxicity to red blood cells.

Abstract
BACKGROUND A versatile strategy for protein-surface coupling in biochips exploits the affinity for polyhistidine of the nitrilotriacetic acid (NTA) group loaded with Ni(II). Methods based on optical reflectivity measurements such as spectroscopic ellipsometry (SE) allow for label-free, non-invasive monitoring of molecule adsorption/desorption at surfaces. RESULTS This paper describes a SE study about the interaction of hexahistidine (His6) on gold substrates functionalized with a thiolate self-assembled monolayer bearing the NTA end group. By systematically applying the difference spectra method, which emphasizes the small changes of the ellipsometry spectral response upon the nanoscale thickening/thinning of the molecular film, we characterized different steps of the process such as the NTA-functionalization of Au, the adsorption of the His6 layer and its eventual displacement after reaction with competitive ligands. The films were investigated in liquid, and ex situ in ambient air. The SE investigation has been complemented by AFM measurements based on nanolithography methods (nanografting mode). CONCLUSION Our approach to the SE data, exploiting the full spectroscopic potential of the method and basic optical models, was able to provide a picture of the variation of the film thickness along the process. The combination of δΔ i +1 ,i (λ), δΨ i +1 ,i (λ) (layer-addition mode) and δΔ(†) i ', i +1(λ), δΨ(†) i ', i +1(λ) (layer-removal mode) difference spectra allowed us to clearly disentangle the adsorption of His6 on the Ni-free NTA layer, due to non specific interactions, from the formation of a neatly thicker His6 film induced by the Ni(II)-loading of the NTA SAM.

Abstract
The detection of Hg(2+) has attracted considerable attention because of the serious health and environmental problems caused by it. Herein, a novel ratiometric fluorescent chemsensor (GQDs-SR) based on the fluorescence resonance energy transfer (FRET) process for detecting of Hg(2+) was designed and synthesized with rhodamine derivative covalently linked onto graphene quantum dots. In this sensor, the graphene quantum dots (GQDs) served as energy donor and the rhodamine derivative turned into an energy acceptor when encountered Hg(2+). The chemsensor exhibited high selectivity, low cytotoxicity, biocompatibility and good water solubility. The results of intracellular imaging experiment demonstrated that GQDs-SR was cell permeable and could be used for monitoring Hg(2+) in living cells, and it was also successfully applied to the detection of Hg(2+) in practical water samples.

Abstract
Protein microarray technology is becoming the method of choice for identifying protein interaction partners, detecting specific proteins, carbohydrates and lipids, or for characterizing protein interactions and serum antibodies in a massively parallel manner. Availability of the well-established instrumentation of DNA arrays and development of new fluorescent detection instruments promoted the spread of this technique. Fluorescent detection has the advantage of high sensitivity, specificity, simplicity and wide dynamic range required by most measurements. Fluorescence through specifically designed probes and an increasing variety of detection modes offers an excellent tool for such microarray platforms. Measuring for example the level of antibodies, their isotypes and/or antigen specificity simultaneously can offer more complex and comprehensive information about the investigated biological phenomenon, especially if we take into consideration that hundreds of samples can be measured in a single assay. Not only body fluids, but also cell lysates, extracted cellular components, and intact living cells can be analyzed on protein arrays for monitoring functional responses to printed samples on the surface. As a rapidly evolving area, protein microarray technology offers a great bulk of information and new depth of knowledge. These are the features that endow protein arrays with wide applicability and robust sample analyzing capability. On the whole, protein arrays are emerging new tools not just in proteomics, but glycomics, lipidomics, and are also important for immunological research. In this review we attempt to summarize the technical aspects of planar fluorescent microarray technology along with the description of its main immunological applications.

Abstract
Hollow nickel silicate nanospheres (NiSiO3 NSs) with hierarchical shells were hydrothermally synthesized by using silica spheres as a template. The NiSiO3 NSs have an average diameter of 250 nm with a shell thickness of 50 nm, and the hierarchical shell consists of a large number of sheets. By taking advantage of the high affinity of Ni(2+) toward histidine-tagged (His-tagged) proteins, hollow NiSiO3 NSs can be used to enrich and separate His-tagged proteins directly from a mixture of lysed cells. Results indicated that the hollow NiSiO3 NSs presented negligible nonspecific protein adsorption and a high protein binding ability with a high binding capacity of 13.2 mmol g(-1). Their specificity and affinity toward His-tagged proteins remained after recycling 5 times. The hollow NiSiO3 NSs are especially suitable for rapid purification of His-tagged proteins.

Abstract
The effects that nanometer-sized matrices have on the properties of molecules encapsulated within the nanomatrix are not fully understood. In this work, dye-doped silica nanoparticles were employed as a model for studying the effects of a nanomatrix on the fluorescence quantum yield of encapsulated dye molecules. Two types of dye molecules were selected based on their different responses to the surrounding media. Several factors that affect fluorescence quantum yields were investigated, including aggregation of dye molecules, diffusion of atmospheric oxygen, concentration of dye molecules, and size of the nanomatrix. The results showed that the silica nanomatrix has a varied effect on the fluorescence quantum yield of encapsulated dye molecules, including enhancement, quenching and insignificant changes. Both the properties of dye molecules and the conditions of the nanomatrix played important roles in these effects. Finally, a physical model was proposed to explain the varied nanomatrix effects on the fluorescence quantum yield of encapsulated dye molecules.

Abstract
In this report, we used stepwise orthogonal click chemistry (SOCC) involving strain-promoted azide-alkyne cycloaddition (SPAAC) and microwave-assisted Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) to assemble an anticancer drug (paclitaxel, PTX) and a targeting ligand (trivalent galactoside, TGal) on a fluorescent silicon oxide nanoparticle (NP) by using dialkyne linker 8 as a bridge. The fluorescent NH2@Cy3SiO2NP was fabricated using a competition method to incorporate Cy3 without loss of the original surface amine density on the NPs. The concept of SOCC was first investigated in a solution-phase model study that showed quantitative reaction yield. In the fabrication of TGal-PTX@Cy3SiO2NP, the expensive compound azido-functionalized PTX 12 used in SPAAC can be easily recovered due to the absence of other reagents in the reaction mixture. High loading of the sugar ligand on the NP surface serves a targeting function and also overcomes the low water solubility of PTX. Confocal fluorescence microscopy and cytotoxicity assay showed that TGal-PTX@Cy3SiO2NP was taken up by HepG2 cells and was affected by the microtubule skeleton in these cells and inhibited the proliferation of these cells in a dose-dependent manner. The presence of a fluorescent probe, a targeting ligand, and an anticancer drug on the multifunctional TGal-PTX@Cy3SiO2NP allows for real-time imaging, specific cancer-cell targeting, and the cell-killing effect which is better than free PTX.

Abstract
Nanoparticle-protein conjugates have potential for numerous applications due to the combination of the properties of both components. In this paper we studied the conjugation of horse heart cytochrome c with ZnO nanoparticles modified by mercaptoacetic acid (MAA) which may be a material with great potential in anticancer therapy as a consequence of synergic effect of both components. Cyt c adsorption to the ZnO-MAA NPs surface was studied by UV-vis spectroscopy and by a dynamic light scattering in various pH. The results indicate that the optimal pH for the association of protein with modified nanoparticles is in range 5.8-8.5 where 90-96% of cytochrome c was assembled on ZnO-MAA nanoparticles. The interaction of proteins with nanoparticles often results in denaturation or loss of protein function. Our observations from UV-vis spectroscopy and circular dichroism performed preserved protein structure after the interaction with modified nanoparticles.

Abstract
A silver nanoparticle (AgNP)-enhanced fluorescence resonance energy transfer (FRET) sensing system is designed for the sensitive detection of human platelet-derived growth factor-BB (PDGF-BB). Fluorophore-functionalized aptamers and quencher-carrying strands hybridized in duplex are coupled with streptavidin (SA)-functionalized nanoparticles to form a AgNP-enhanced FRET sensor. The resulting sensor shows lower background fluorescence intensity in the duplex state due to the FRET effect between fluorophores and quenchers. Upon the addition of PDGF-BB, the quencher-carrying strands (BHQ-2) of the duplex are displaced leading to the disruption of the FRET effect. As a result, the fluorescent intensity of the fluorophore-aptamer within the proximity of the AgNP is increased. When compared to the gold nanoparticle (AuNP)-based FRET and bare FRET sensors, the AgNP-based FRET sensor showed remarkable increase in fluorescence intensity, target specificity, and sensitivity. Results also show versatility of the AgNP in the enhancement of sensitivity and selectivity of the FRET sensor. In addition, a good linear response was obtained when the PDGF-BB concentrations are in the ranges of 100-500 and 6.2-50 ng/mL with the detection limit of 0.8 ng/mL.

Abstract
Interest in developing diverse nanoparticle (NP)-biological composite materials continues to grow almost unabated. This is motivated primarily by the desire to simultaneously exploit the properties of both NP and biological components in new hybrid devices or materials that can be applied in areas ranging from energy harvesting and nanoscale electronics to biomedical diagnostics. The utility and effectiveness of these composites will be predicated on the ability to assemble these structures with control over NP/biomolecule ratio, biomolecular orientation, biomolecular activity, and the separation distance within the NP-bioconjugate architecture. This degree of control will be especially critical in creating theranostic NP-bioconjugates that, as a single vector, are capable of multiple functions in vivo, including targeting, image contrast, biosensing, and drug delivery. In this review, a perspective is given on current and developing chemistries that can provide improved control in the preparation of NP-bioconjugates. The nanoscale properties intrinsic to several prominent NP materials are briefly described to highlight the motivation behind their use. NP materials of interest include quantum dots, carbon nanotubes, viral capsids, liposomes, and NPs composed of gold, lanthanides, silica, polymers, or magnetic materials. This review includes a critical discussion on the design considerations for NP-bioconjugates and the unique challenges associated with chemistry at the biological-nanoscale interface-the liabilities of traditional bioconjugation chemistries being particularly prominent therein. Select bioorthogonal chemistries that can address these challenges are reviewed in detail, and include chemoselective ligations (e.g., hydrazone and Staudinger ligation), cycloaddition reactions in click chemistry (e.g., azide-alkyne cyclyoaddition, tetrazine ligation), metal-affinity coordination (e.g., polyhistidine), enzyme driven modifications (e.g., HaloTag, biotin ligase), and other site-specific chemistries. The benefits and liabilities of particular chemistries are discussed by highlighting relevant NP-bioconjugation examples from the literature. Potential chemistries that have not yet been applied to NPs are also discussed, and an outlook on future developments in this field is given.

Abstract
Lipid-based oil-filled nanoparticles (NPs) with a high concentration of surface-chelated nickel (Ni-NPs) were successfully prepared using a Brij 78-NTA-Ni conjugate synthesized with Brij 78 (Polyoxyethylene (20) stearyl ether) and nitrilotriacetic acid (NTA). The facile incorporation of the Brij 78-NTA-Ni conjugate into the NP formulation allowed up to 90% Ni incorporation, which was a significant improvement over the previously used standard agent DOGS-NTA-Ni which led to ~6% Ni incorporation. The Ni-NPs were targeted to the highly epidermal growth factor receptor (EGFR)-overexpressing epidermoid carcinoma cells A431. This was accomplished using a novel high affinity histidine×6-tagged EGFR-binding Z domain (heptameric Z(EGFR) domain). In vitro cell uptake studies showed enhanced internalization (up to 90%) of the targeted Ni-NPs in A431 cells with only ≤10% internalization of the untargeted Ni-NPs. ICP-MS analysis used to quantify the amount of Ni in the cells were in close agreement with flow cytometry studies, which showed a dose dependent increase in the amount of Ni with the targeted Ni-NPs. Cell uptake competition studies showed that internalization of the targeted Ni-NPs within the cells was competed off with free heptameric Z(EGFR) domain at concentrations of 8.75ng/mL or higher. In vivo studies were carried out in nude mice bearing A431 tumors to determine the biodistribution and intracellular delivery. Near Infrared (NIR) optical imaging studies using Alexa750-labeled heptameric Z(EGFR) domain showed localization of 19% of the total detected fluorescence intensity in the tumor tissue, 28% in the liver and 42% in the kidneys 16h post i.v. injection. ICP-MS analysis showed almost a two-fold increase in the amount of intracellular Ni with the targeted Ni-NPs. These new Ni-NPs could be a very useful tool for targeting and drug delivery to a wide range of EGFR positive cancers.

Abstract
Methods based on Förster (or fluorescence) resonance energy transfer (FRET) are widely used in various areas of bioanalysis and molecular biology, such as fluorescence microscopy, quantitative real-time polymerase chain reaction (PCR), immunoassays, or enzyme activity assays, just to name a few. In the last years, these techniques were successfully implemented to multiplex biomolecular screening on microarrays. In this review, some fundamental considerations and practical approaches are outlined and it is demonstrated how this very sensitive (and distance-dependent) method can be utilized for microarray-based high-throughput screening (HTS) with a focus on protein microarrays. The advantages and also the demands of this dual-label technique in miniaturized multiplexed formats are discussed with respect to its potential readout modes, such as intensity, dual wavelength, and time-resolved FRET detection.

Abstract
Intracellular delivery of functional macromolecules using peptide transduction domains (PTDs) is an exciting technology with both experimental and therapeutic applications. Recent data indicate that PTD-mediated transduction occurs via fluid-phase macropinocytosis involving an intracellular pH drop to approximately 5. Nitrilotriacetic acid (NTA)-coordinated metals avidly bind hexahistidine-tagged macromolecules, including peptides and proteins. Histidine's imidazole ring has a pK(a) of 6, making this an attractive target for the biological pH drop of PTD-mediated macropinocytotic delivery. The objective of this study was to develop a pH-sensitive PTD delivery peptide (NTA(3)-PTD). We demonstrate the in vitro function of this novel peptide by delivering fluorescently labeled peptides (1.6 kDa) and functional enzymes, beta-galactosidase (119 kDa) and Cre recombinase (37 kDa). Furthermore, the NTA(3)-PTD peptide was able to deliver functional Cre recombinase in an in vivo mouse model.

Optimisation of a multivalent Strep tag for protein detection. Biophys Chem 2010; 152:170-7. [PMID: 20970240 DOI: 10.1016/j.bpc.2010.09.005] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2010] [Revised: 09/20/2010] [Accepted: 09/20/2010] [Indexed: 02/05/2023]
Abstract
The Strep tag is a peptide sequence that is able to mimic biotin's ability to bind to streptavidin. Sequences of Strep tags from 0 to 5 have been appended to the N-terminus of a model protein, the Stefin A Quadruple Mutant (SQM) peptide aptamer scaffold, and the recombinant fusion proteins expressed. The affinities of the proteins for streptavidin have been assessed as a function of the number of tags inserted using a variety of labelled and label-free bioanalytical and surface based methods (Western blots, microarray assays and surface plasmon resonance spectroscopy). The binding affinity increases with the number of tags across all assays, reaching nanomolar levels with 5 inserts, an observation assigned to a progressive increase in the probability of a binding interaction occurring. In addition a novel interfacial FRET based assay has been developed for generic Strep tag interactions, which utilises a conventional microarray scanner and bypasses the requirement for expensive lifetime imaging equipment. By labelling both the tagged StrepX-SQM(2) and streptavidin targets, the conjugate is primed for label-free FRET based displacement assays.

Abstract
The use of peptides to mediate the delivery and uptake of nanoparticle (NP) materials by mammalian cells has grown significantly over the past 10 years. This area of research has important implications for the development of new therapeutic materials and for the emerging field of NP-mediated drug delivery. In this review, we highlight recent advances in the delivery of various NPs by some of the more commonly employed cellular delivery peptides and discuss important related factors such as NP–peptide bioconjugation, uptake efficiency, intracellular fate and toxicity. We also highlight various demonstrations of therapeutic applications of NP–peptide conjugates where appropriate. The paper concludes with a brief forward-looking perspective discussing what can be expected as this field develops in the coming years.

Abstract
Multifunctional nanoparticles are among the most exciting nanomaterials with promising applications in analytical chemistry. These applications include (bio)sensing, (bio)assays, catalysis and separations. Although most of these applications are based on the magnetic, optical and electrochemical properties of multifunctional nanoparticles, other aspects such as the synergistic effect of the functional groups and the amplification effect associated with the nanoscale dimension have also been observed. Considering not only the nature of the raw material but also the shape, there is a huge variety of nanoparticles. In this review only magnetic, quantum dots, gold nanoparticles, carbon and inorganic nanotubes as well as silica, titania and gadolinium oxide nanoparticles are addressed. This review presents a narrative summary on the use of multifunctional nanoparticles for analytical applications, along with a discussion on some critical challenges existing in the field and possible solutions that have been or are being developed to overcome these challenges.

Abstract
The hexahistidine (His(6))/nickel(II)-nitrilotriacetic acid (Ni(2+)-NTA) system is widely used for affinity purification of recombinant proteins. The NTA group has many other applications, including the attachment of chromophores, fluorophores, or nanogold to His(6) proteins. Here we explore several applications of the NTA derivative, (Ni(2+)-NTA)(2)-Cy3. This molecule binds our two model His(6) proteins, N-ethylmaleimide sensitive factor (NSF) and O(6)-alklyguanine-DNA alkyltransferase (AGT), with moderate affinity (K approximately 1.5 x 10(6) M(-1)) and no effect on their activity. Its high specificity makes (Ni(2+)-NTA)(2)-Cy3 ideal for detecting His(6) proteins in complex mixtures of other proteins, allowing (Ni(2+)-NTA)(2)-Cy3 to be used as a probe in crude cell extracts and as a His(6)-specific gel stain. (Ni(2+)-NTA)(2)-Cy3 binding is reversible in 10mM ethylenediaminetetraacetic acid (EDTA) or 500 mM imidazole, but in their absence it exchanges slowly (k(exchange) approximately 5 x 10(-6) s(-1) with 0.2 microM labeled protein in the presence of 1 microM His(6) peptide). Labeling with (Ni(2+)-NTA)(2)-Cy3 allows characterization of hydrodynamic properties by fluorescence anisotropy or analytical ultracentrifugation under conditions that prevent direct detection of protein (e.g., high ADP absorbance). In addition, fluorescence resonance energy transfer (FRET) between (Ni(2+)-NTA)(2)-Cy3-labeled proteins and suitable donors/acceptors provides a convenient assay for binding interactions and for measurements of donor-acceptor distances.

Abstract
Nitrilotriacetic acid (NTA) has moderate affinity (10 μM) for hexahistidine (His6) and is widely used in the purification of His6-tagged proteins. The affinity can be increased significantly (10 nM) through multivalency such as using a tris-NTA. We show that the binding affinity of tris-NTA is dependent on the flexibility and length of the spacer between the mono-NTA and the scaffold: the shorter the spacer, the higher the affinity. A series of biotinylated tris-NTA having different spacers were synthesized and used to prepare tris-NTA sensor chips for surface plasmon resonance measurement of binding affinity. Subnanomolar affinity can be achieved with a short spacer. The new high-affinity tris-NTA enables the formation of stable complexes with hexahistidine containing molecules and provides a convenient method to noncovalently attach proteins to various surfaces.

Abstract
This article describes strategies for achieving fluorescence enhancement in optical biochips. Two strategies are discussed: plasmonic enhancement, which is due to the localized surface plasmon resonance of metal nanostructures that are adjacent to the fluorescent labels in optical immunoassays; and the use of high-brightness silica nanoparticles as enhanced labels. We present a review of the state-of-the-art in both areas, including synthesis techniques for the metal and silica nanoparticles and the use of the nanoparticles in optical immunoassays. Data are presented that highlight the key design parameters which influence the level of enhancement and model assay data are presented that illustrate potential enhancements in assay performance.

Abstract
The interaction between synthetic materials and biomolecules plays an important role in biomedical and pathological sciences. An important issue in these interactions is control of stoichiometry. The interaction between NTA ligands and proteins with six consecutive His residues has been widely used for protein purification. Control of stoichiometry is an important issue in applying this recognition strategy to the creation of defined nanoparticle-protein conjugates. In this communication we report the direct control of particle-protein stoichiometry through variation of nickel chloride concentration, as demonstrated through fluorescence and gel electrophoresis.

Abstract
For labeling proteins (streptavidin and fibronectin) by luminescent aminated nanoparticles, an interesting strategy that requires neither activation nor chemical pre- or post-treatment was explored. Because biomolecules are easily rendered luminescent after reaction with organic dyes carrying isothiocyanate moiety, phenylene diisothiocyanate (DITC) was used for covalently binding proteins onto luminescent hybrid gadolinium oxide nanoparticles whose ability to combine imaging and therapy was recently demonstrated.

Abstract
There is substantial interest in the development of near-infrared dye-doped nanoparticles (NPs) for a range of applications including immunocytochemistry, immunosorbent assays, flow cytometry, and DNA/protein microarray analysis. The main motivation for this work is the significant increase in NP fluorescence that may be obtained compared with a single dye label, for example Cy5. Dye-doped NPs were synthesised and a reduction in fluorescence as a function of dye concentration was correlated with the occurrence of homo-Förster resonance energy transfer (HFRET) in the NP. Using standard analytical expressions describing HFRET, we modelled the fluorescence of NPs as a function of dye loading. The results confirmed the occurrence of HFRET which arises from the small Stokes shift of near-infrared dyes and provided a simple method for predicting the optimum dye loading in NPs for maximum fluorescence. We used the inverse micelle method to prepare monodispersed silica NPs. The NPs were characterised using dynamic light scattering, UV spectroscopy, and transmission electron microscopy (TEM). The quantum efficiency of the dye inside the NPs, as a function of dye loading, was also determined. The fluorescent NPs were measured to be approximately 165 times brighter than the free dye, at an optimal loading of 2% (w/w). These experimental results were in good agreement with model predictions.

Abstract
In the last decade, the field of nanoparticle (NP) technology has attracted immense interest in bioimaging and biosensing research. This technology has demonstrated its capability in obtaining sensitive data in a noninvasive manner, promising a breakthrough in early-stage cancer diagnosis, stem cell tracking, drug delivery, pathogen detection and gene delivery in the near future. However, successful and wide application of this technology relies greatly on robust NP engineering and synthesis methodologies. The NP development steps involve design, synthesis, surface modification and bioconjugation. Each of these steps is critical in determining the overall performance of NPs. It is desirable to obtain NPs that are highly sensitive, stable, imageable, biocompatible and targetable. It is also desirable to obtain multimodal/multifunctional NPs that will enable imaging/sensing of the target using multiple imaging/sensing modalities. In this review, we focus on silica NPs that have been developed for biosensing applications and silica-based multimodal/multifunctional NPs for bioimaging applications.
