Abstract
Nuclease-resistant assay probes are of significant importance for biochemical analysis and disease diagnosis. In this contribution, a reconfigurable lipidic moiety-attached DNA nanoparticle (LDN) is constructed from a cholesterol-conjugated multifunctional hairpin-type DNA probe (Chol-DP) by hydrophobicity-mediated self-assembly. The LDN holds high serum stability and displays a low false-positive signal even in a complex biological milieu. The hydrophobic cholesterol moiety enables the hydrophobicity-mediated assembly, while hydrophilic DNA sequence serves as a recognition element and a polymerization template. The initiator-activated strand displacement amplification (SDA) reaction can convert the hairpin-shaped probe into rigid double-stranded DNA (dsDNA), causing the conformational rearrangement-based LDN swelling that can be used to reliably and fluorescently signal the cancer-related p53 gene. The size increase and structural reconfiguration are confirmed by dynamic light scattering (DLS) analysis and confocal microscopy imaging, respectively. Target p53 is specifically detected down to 10 pM. The whole assay process involved only several simple mixing steps. Recovery test and blind test further confirm the feasibility of the use of the LDN for the detection of target DNA in a complex biological milieu, indicating a promising nanotool for biomedical applications.

Abstract
Sensitive and selective detection of proto-oncogenes, especially recognition of point mutation, is of great importance in cancer diagnosis. Here, a ligation-mediated technique is demonstrated for the construction of an intertwined three-dimensional DNA nanosheet (3D SDN) on an electrode surface from only two palindromic hairpin probes (HP1 and HP2), creating a powerful electrochemical biosensor (E-biosensor) for the detection of the p53 gene. First, a capturing probe (CP) is immobilized on an electrode surface via Au-S chemistry, forming an electrochemical sensing interface. In the presence of the target p53 (T), the triggering probe is covalently linked to CP by a ligase. Moreover, target hybridization/ligation/dehybridization process is repeated, amplifying the target hybridization event and increasing the content of surface-confined triggering fragments. As a result, HP1 is opened and in turn interacts with HP2, forming intertwined 3D SDN where HP1 and HP2 are alternately arranged in parallel. Common hybridization and interaction between palindromic fragments are responsible for the assembly in the horizontal and vertical directions, respectively. An electrochemical indicator, methylene blue (MB), can be inserted into 3D SDN, generating a strong electrochemical signal. Utilizing the 3D SDN-based E-biosensor, the target DNA is detected down to 3 fM with a linear response range from 10 fM to 10 nM. Single point mutations are reliably identified even in fetal bovine serum and cellular homogenate. Because of the several advantages of simple design, good universality, inexpensive instrumentation, high assay specificity, and sensitivity, the 3D SDN-based E-biosensor is expected to provide a potential platform for screening point mutation required by early clinical diagnostics and medical research.

Abstract
The development of a versatile biosensing platform to screen specific DNA sequences is still an essential issue of molecular biology research and clinic diagnosis of genetic disease. In this work, we for the first time reported a double-stem hairpin probe (DHP) that was simultaneously engineered to incorporate a DNAzyme, DNAzyme's complementary fragment and nicking enzyme recognition site. The important aspect of this hairpin probe is that, although it is designed to have a long ds DNA fragment, no intermolecular interaction occurs, circumventing the sticky-end pairing-determined disadvantages encountered by classic molecular beacon. For the DHP-based colorimetric sensing system, as a model analyte, cancer-related DNA sequence can trigger a cascade polymerization/nicking cycle on only one oligonucleotide probe. This led to the dramatic accumulation of G-quadruplexes directly responsible for colorimetric signal conversion without any loss. As a result, the target DNA is capable of being detected to 1 fM (six to eight orders of magnitude lower than that of catalytic molecular beacons) and point mutations are distinguished by the naked eye. The described DHP as a-proof-of-concept would not only promote the design of colorimetric biosensors but also open a good way to promote the diagnosis and treatment of genetic diseases.

Abstract
Molecular beacon (MB) is usually explored as a convenient probe for various bioassays. In an enzymatic polymerization-based biosensing system, primer, and MB, sometimes involving other oligonucleotides, are often required to collaboratively generate an amplified fluorescent signal to detect target molecules with high sensitivity and specificity. In the current study, a multifunctional primer-integrated MB (MP-MB) was developed to detect the p53 tumor suppressor gene. Compared with the traditional MB, our MP-MB can not only selectively identify the target of interest and signal sensitively its hybridization event, but also act as the primer during enzymatic polymerization. Specifically, hybridization of MP-MB to target p53 gene restored the fluorescence intensity and activated the pre-locked primer designed by changing the molecular configuration of MP-MB. Moreover, the p53 gene could be detected down to 1nM with a linear response range of 1×10(-9)-3×10(-7)M, and p53 gene point mutation was readily distinguished from the wild-type one. Its potential application as a primer of replication in enzymatic polymerization-based assay systems was validated by running parallel gel electrophoreses in comparison with the native counterpart of MP-MB without any chemical modification. Owning to its excellent assay characteristics, less species requirement, broad sequence diversity and preserved intrinsic bioactivity, the proof-of-concept of MP-MB exhibits a great potential in various biomedical applications.

Abstract
Noble metal nanoparticles are currently of great interest because of their unique optical properties and potential applications in disease diagnostics and cancer treatment. In the present work, a discovery was reported that dsDNA with terminal thiols at its two ends could lie easily flat onto the gold nanoparticle (GNP) surface rather than cross linked different GNPs, indicating an unique self-assembly behavior of newly-designed molecules on GNPs. This could intensively stabilize gold nanoparticles against aggregation even at a high salt concentration. On the basis of this discovery, a novel light-up colorimetric sensing strategy was developed for the detection of p53 gene by combining with the cyclical nucleic acid strand-displacement polymerization (CNDP). For the described colorimetric system, GNPs require no any surface functionalization, and target recognition reaction and CNDP amplification could be conducted under the optimized conditions to achieve a high efficiency. The high detection sensitivity and desirable selectivity are achieved, and the potential practical application was demonstrated. Besides, this sensing system can function in a wide range of salts, making it a suitable platform to cooperate with many biological processes.

Abstract
Nanomaterials as tracing tags have been widely used in biosensors with high sensitivity and selectivity. In this work, a signal amplification electrochemical aptamer sensing strategy for the detection of protein was designed by combining the hybridization-inducing aggregate of DNA-functionalized silver nanoparticles (AgNPs) and differential pulse stripping voltammetry (DPSV) detection. The multiprobes containing hybridization DNA and aptamers were anchored onto the silver nanoparticles. The protein assay was prepared through the immobilization of capture aptamer that specifically recognizes platelet-derived growth factor (PDGF-BB) on gold nanoparticles modified screen-printed electrode (SPE) array. After a sandwich-type reaction, two kinds of DNA-modified AgNPs were simultaneously added on the electrode surface for specifically recognizing PDGF-BB and forming the AgNPs aggregate caused by in situ hybridization of DNA. Compared to the signal-labeled tag, the tracing aggregate tags showed a strong electroactivity for signal amplification through stripping detection of silver after preoxidation. By using the hybridization-inducing aggregate as electrochemical readouts, the sensor showed wide linear range and low detection limit. The hybridization-inducing AgNPs aggregate were further used as tracing tags in multiplied proteins assays for PDGF-BB and thrombin by using the SPE array chip as sensing platform. The cross-talk between different aptamer-modified electrodes on the same array was avoided because of the advantage of labeled AgNPs. The array detection was also applied in the logic gate operation. The proposed method described here is ideal for multianalytes determination in clinical diagnostics with good analytical performance.

Abstract
A composite photoresist has been developed for the direct photopatterning of electrodes useful as biochip substrates. The material is composed of SU-8 polymer added with graphite carbon filler which enables patterning of conductive thin films (22 μm) on both glass substrate and transparency flexible film with a standard UV photolithography protocol. The resolution obtained using the conductive composite compared well with the bare resist, with lateral resolutions of 5 and 10 μm for bare and conductive resists, respectively. The obtained electrodes, after an electrochemical pre-treatment, exhibited very good electrochemical behaviors, opening the path to various electrochemical detections and grafting possibilities. In order to demonstrate the potentialities of the developed material in the biosensors and biochips field, DNA probes were electrografted, using diazonium chemistry, directly at the composite photoresist surface. Target oligonucleotide interactions were detected using chemiluminescent labeling and a satisfactory detection limit of 0.25 nM target sequence was demonstrated with a detection ranging over three orders of magnitude.

Abstract
A novel disposable solid-state electrochemiluminescent (ECL) biosensor was fabricated by immobilizing glucose oxidase and surface-unpassivated CdTe quantum dots (QDs) on a screen-printed carbon electrode (SPCE). The surface morphology of the biosensor was characterized with scanning electron microscopy and atomic force microscopy. With dissolved O(2) as an endogenous coreactant, QDs/SPCE showed strong ECL emission in pH 9.0 HCl-Tris buffer solution with low ECL peak potential at -0.89 V. The ECL intensity was twice that with hydrogen peroxide as coreactant at the same concentration. This phenomenon meant the ECL decreased upon consumption of dissolved O(2) and thus could be applied to the construction of oxidase-based ECL biosensors. With glucose oxidase as a model enzyme, the biosensor showed rapid response to glucose with a linear range of 0.8 to 100 μM and a detection limit of 0.3 μM. Further detection of glucose contained in human serum samples showed acceptable sensitivity and selectivity. This work provided a promising application of QDs in ECL-based disposable biosensors.

Abstract
The existing isothermal polymerization-based signal amplification assays are usually accomplished via two strategies: rolling circle amplification (RCA) and circular strand-displacement polymerization. In essence, the two techniques are based on cyclical nucleic acid strand-displacement polymerization (CNDP), limiting the application of isothermal polymerization in medical diagnosis and bioanalysis. In the present study, circular common target molecule (non-nucleic acid strand)-displacement polymerization (CCDP) is developed to amplify the fluorescence signal for biomolecule assays, extending isothermal polymerization to an aptameric system without any medium. Via combining an aptamer with a common hairpin DNA probe, we designed a self-blocked fluorescent bifunctional oligonucleotide probe (signaling probe) for the homogeneous parallel detection of two disease markers, PDGF-BB and the p53 gene. On the basis of CNDP and CCDP signal amplification, highly sensitive (e.g., detecting PDGF down to the concentration level of 1.8 × 10(-10) M) and selective detection (no interference even in the presence of a significantly higher concentration (7-200 times) of nontarget proteins) was accomplished, and the linear response range was considerably widened. Furthermore, the bifunctional signaling probe exhibits impressive simplicity, convenience, and short detection time. Herein, the design of the signaling probe was described, factors influencing fluorescence signal were investigated, analytical properties were characterized in detail, and the assay application in a complex medium was validated. The proposed biosensing scheme as a proof-of-concept is expected to promote the application of oligonucleotide probes in basic research and medical diagnosis.

Abstract
We put forward an impedometric protein-based biosensor platform suitable for point-of-care diagnostics. A hand-held scale impedance reader system is described for the detection of corresponding physiochemical changes as the immobilized proteins bind to the analyte molecules in the proximity of the microfabricated electrodes. Specifically, we study the viability of this approach for glucose biosensing purposes using genetically engineered glucokinase as receptor proteins. The proposed reagent-less biosensor offers a high sensitivity of 0.5 mM glucose concentration level in the physiologically relevant range of 0.5 mM to 7.5 mM with less than 10 s response time.

Abstract
A novel method is presented for the specific and direct detection of bacteria using bacteriophages as recognition receptors immobilized covalently onto functionalized screen-printed carbon electrode (SPE) microarrays. The SPE networks were functionalized through electrochemical oxidation in acidic media of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) by applying a potential of +2.2 V to the working electrode. Immobilization of T4 bacteriophage onto the SPEs was achieved via EDC by formation of amide bonds between the protein coating of the phage and the electrochemically generated carboxylic groups at the carbon surface. The surface functionalization with EDC, and the binding of phages, was verified by time-of-flight secondary ion mass spectrometry. The immobilized T4 phages were then used to specifically detect E. coli bacteria. The presence of surface-bound bacteria was verified by scanning electron and fluorescence microscopies. Impedance measurements (Nyquist plots) show shifts of the order of 10(4) Omega due to the binding of E. coli bacteria to the T4 phages. No significant change in impedance was observed for control experiments using immobilized T4 phage in the presence of Salmonella. Impedance variations as a function of incubation time show a maximum shift after 20 min, indicating onset of lysis, as also confirmed by fluorescence microscopy. Concentration-response curves yield a detection limit of 10(4) cfu/mL for 50-microL samples.

Abstract
Miniaturization of biosensors is envisaged by the development of biochips consisting of parallel microarray patterns of binding sites on rigid substrates, such as glass or silicon. Thin plastic substrates are promising flexible alternatives because of the possibility for large-area roll-to-roll manufacturing of disposable chips at lower costs. Mature optical lithography technology faces many challenges when used to pattern flexible foils as a result of the substrate instabilities, especially at higher temperatures. In this work, flexible biochips with gold electrode patterns were fabricated on thin polyethylene naphthalate (PEN) foils using photolithography. The gold electrode structures of the chips were manufactured by direct metal patterning and by lift-off processing. Both methodologies resulted in well-defined electrode patterns as concluded from optical microscopy and scanning electron microscopy (SEM) characterization and resistance measurements. The biochips were successfully employed for the electrical and optical detection of DNA molecules. The DNA detection was based on the immobilization of capture DNA between electrode gaps, hybridization with biotin-labeled target DNA, and enzymatic silver enhancement.

Abstract
BACKGROUND Most processes for fabricating biosensors applied to screen-printed carbon electrodes (SPCEs) are complex. This study presents a novel one-step process for manufacturing electrodes for injection-molding biosensors. METHODS During the sensor-fabrication process, barrel-plated gold electrodes were inserted into an injection-molded base. The electrode directly touched the electrical contact of a meter. We analyzed technical measurements for this biosensor, including tests of the measurement range, within-run imprecision, and between-meter imprecision. In clinical trials, experienced technicians tested 3 alternative sites (fingertip, palm, and arm). The results were simultaneously compared with plasma values obtained with the hexokinase method on the Olympus AU640 instrument. Analytical results were evaluated according to International Standards Organization 15197 (ISO 15197:2003) criteria and by Clarke error grid analysis (EGA), and CVs were calculated to evaluate within-run imprecision. RESULTS The glucose measurement range was 0.6- 33.3 mmol/L (y = 0.96x + 0.07 mmol/L; r(2) = 0.9977). The CVs in the within-run imprecision test were 1.7%-3.5%, and the overall CV was 2.1%, indicating good reproducibility of results. The Student t-tests of mean values from 5 meters revealed statistically insignificant differences (P > 0.05). In clinical trials, the agreement of the Rightest GM310 meter results with those of a laboratory method complied with ISO 15197:2003 criteria. In the EGA, 100% of the values were within the acceptable zones (A + B), and the proportion of values within zone A exceeded 95%. CONCLUSIONS The Bionime Rightest GM310 meter applied a simplified process for biosensor fabrication and displayed acceptable performance for monitoring glucose concentrations at alternative test sites.

Abstract
A new multidetection biosensor has been developed using the electrochemical properties of cylinder-shaped conducting polypyrrole grown on miniaturized graphite electrodes. Our objective was to conceive a sensitive, labelless and real-time DNA sensor for biomedical diagnosis. In a first step, copolymers bearing both ferrocene redox markers and oligonucleotide probes were selectively electro-addressed on microchip electrodes. Then, the study of their voltammetric response upon the addition of DNA targets revealed that the hybridization was efficiently transduced through the variation of ferrocene oxidation intensity. Using this technique, a good selectivity between Human Immunodeficiency Virus and Hepatitis B Virus targets was obtained. It was indeed possible to directly follow the hybridization. Complementary DNA detection limit reached 100 pM (3 fmol in 30 microL), which represents a good performance for such a practical, labelless and real-time sensor.

Abstract
An original method for the enhancement of chemiluminescent (CL) on-chip detection of protein and oligonucleotides is presented. This enhancement is based on the electrodeposition of a gold nanostructured layer onto a screen-printed (SP) carbon microarray prior to the immobilization of biomolecules through a well-established diazonium adduct electrodeposition. Morphological studies of the Au layer (optical and atomic force microscopy) show that the metal film is composed of nanostructured 800 nm diameter particles covering the entire graphite surface and yielding a high surface area. Using these modified SP microarrays, enhancement factors of 229 and 126 were obtained for prostate-specific antigen (PSA) and p53 oligonucleotide detection, respectively. These enhancements were associated with three different phenomena: an enhancement of the catalyzed chemiluminescent reaction by the gold surface, an increase of the specific surface area for immobilization of the probe biomolecules, and an opposite quenching effect due to the overlapping of the gold absorption and CL emission peaks. For free PSA and target oligonucleotide detection, enhanced performances were obtained, giving detection limits of 5 ng/mL and 0.1 nM, respectively.

Abstract
A new method for the pretreatment of screen-printed carbon electrodes (SPCEs) by two successive steps was proposed. In step one, fresh SPCEs were soaked into NaOH with high concentration (e.g. 3 M) for tens to hundreds of minutes, and the resulted electrodes were called as SPCE-I. In step two, SPCE-I were pre-anodized in low concentration of NaOH, which were designated as SPCE-II. The pretreated electrodes showed remarkable enhancement in heterogeneous electron transfer rate constant (k0) increased from 1.6x10(-4) cms(-1) at the fresh SPCE to 1.1x10(-2) cms(-1) at SPCE-I for Fe(CN)6(3-/4-) couple. The peak to peak separation (deltaE(p)) in cyclic voltammetry was reduced from ca. 480 to 84 mV, indicating that the electrochemical reversibility was greatly promoted, possibly due to the removing of polymers/oil binder from the electrode surfaces. The electroactive area (A(ea)) of the electrode was increased by a factor of 17 after pretreatment in step one. Further analysis by the electrochemical impedance method showed that the electron transfer resistance (R(ct)) decreased from ca. 2100 to 1.4 ohms. These pretreated electrodes, especially SPCE-II, exhibited excellent electrocatalytic behavior for the redox of dopamine (DA). Interference from ascorbic acid (AA) in the detection of DA at SPCE-II could be effectively eliminated due to the anodic peak separation (190 mV) between DA and AA, which resulted from the functionalization of the electrode surface in the pretreatment of step two. Under optimum conditions, current responses to DA were linearly changed in two concentration intervals, one was from 3.0x10(-7) to 9.8x10(-6) M, and the other was from 9.8x10(-6) to 3.3x10(-4) M. The detection limit for DA was down to 1.0x10(-7) M.

Abstract
An original immobilisation technology is presented for the development of chemiluminescent protein biochips, suitable for measurement in complex matrices. The immobilisation strategy involved is based on diazotated aniline derivatives, which could be electro-addressed, thus creating a covalent linkage with a conducting material surface. The present electrochemical system is a cost effective and mass-produced carbon paste screen-printed (SP) microarray composed of eight 0.2 mm2 working electrodes, one carbon pseudo-reference electrode and one auxiliary electrode. Rabbit immunoglobulins (IgG) were chemically modified with an aniline derivative (4-carboxymethylaniline) in order to be easily electro-grafted to the SP microarray surface. The possibility of successively electro-address the eight sensing layers of a particular array, with a good reproducibility (more than 80%) and without loss of reactivity was demonstrated. Moreover, these immobilised proteins were subsequently used as a capture agent for the determination of rheumatoid factor (RF) in human sera. The absence of non-specific signal or interference problem enabled the detection of RF values in complex samples in the 5.3-485 IU/ml range with a good correlation with the standard Auraflex ELISA test method.

Abstract
Many advanced medical and biological devices require microscale patterning of cells, proteins, and other biological materials. This article describes the use of piezoelectric ink jet processing in the fabrication of biosensors, cell-based assays, and other microscale medical devices. A microelectromechanical system-based piezoelectric transducer was used to develop uniform fluid flow through nozzles and to prepare well-defined microscale patterns of proteins, monofunctional acrylate ester, sinapinic acid, deoxyribonucleic acid (DNA), and DNA scaffolds on relevant substrates. Our results demonstrate that piezoelectric ink jet deposition is a powerful non-contact, non-destructive additive process for developing biosensors, cell culture systems, and other devices for medical and biological applications.
