Abstract
The key to fabricating complex, hierarchical materials is the control of chemical reactions at various length scales. To this end, the classical model of nucleation and growth fails to provide sufficient information. Here, we illustrate how modern X-ray spectroscopic and scattering in situ studies bridge the molecular- and macro- length scales for assemblies of polyhedrally shaped CoO nanocrystals. Utilizing high energy-resolution fluorescence-detected X-ray absorption spectroscopy, we directly access the molecular level of the nanomaterial synthesis. We reveal that initially Co(acac)3 rapidly reduces to square-planar Co(acac)2 and coordinates to two solvent molecules. Combining atomic pair distribution functions and small-angle X-ray scattering we observe that, unlike a classical nucleation and growth mechanism, nuclei as small as 2 nm assemble into superstructures of 20 nm. The individual nanoparticles and assemblies continue growing at a similar pace. The final spherical assemblies are smaller than 100 nm, while the nanoparticles reach a size of 6 nm and adopt various polyhedral, edgy shapes. Our work thus provides a comprehensive perspective on the emergence of nano-assemblies in solution.

Abstract
The effective surface area of the nanostructured materials is known to play a prime role in catalysis. Here we demonstrate that the shape of the nanostructured materials plays an equally important role in their catalytic activity. Hierarchical CdS microstructures with different morphologies such as microspheres assembled of nanoplates, nanorods, nanoparticles, and nanobelts are synthesized using a simple hydrothermal method by tuning the volume ratio of solvents, i.e., water or ethylenediamine (en). With an optimum solvent ratio of 3:1 water:en, the roles of other synthesis parameters such as precursor's ratio, temperature, and precursor combinations are also explored and reported here. Four selected CdS microstructures are used as photocatalysts for the degradation of methylene blue and photoelectrochemical water splitting for hydrogen generation. In spite of smaller effective surface area of CdS nanoneedles/nanorods than that of CdS nanowires network, the former exhibits higher catalytic activity under visible light irradiation which is ascribed to the reduced charge recombination as confirmed from the photoluminescence study.

Abstract
Mesoporous magnetic nanoparticles (MMNPs) have been synthesized through a facile soft chemical route and are conjugated with multiple therapeutic agents. These MMNPs have the ability to contain and deliver both hydrophilic and hydrophobic drugs simultaneously with the mediation of an AC magnetic field (ACMF). Furthermore, the synthesis and characterization of doxorubicin hydrochloride:paclitaxel (DOX:TXL) and doxorubicin hydrochloride:cisplatin (DOX:Cis-Pt) conjugates are demonstrated. MMNPs show an excellent loading efficiency of ~96:83% (DOX:TXL) and ~93:83% (DOX:Cis-Pt) along with a loading capacity of ~0.002:0.002 mg mg(-1) (DOX:TXL) and ~0.002:0.002 mg mg(-1) (DOX:Cis-Pt), respectively. Over a period of 180 h, a sustained release of drugs is observed and shows a better efficiency at pH 4.3 (~85:63%-DOX:TXL and ~86:73%-DOX:Cis-Pt) compared to that under physiological pH conditions (~28:22%-DOX:TXL and ~26:22%-DOX:Cis-Pt). The MMNPs can release ~37:22% (DOX:TXL) and ~34:25% (DOX:Cis-Pt) within 30 min when triggered by an ACMF (at ~43 °C). The in vitro cytotoxic effect, the ROS generation level and cell cycle distribution analysis of DOX:TXL-MMNPs and DOX:Cis-Pt-MMNPs treated MDA-MB231, MCF-7 and PC3 cancer cells are demonstrated. Enhanced cell apoptosis is observed by thermo-chemotherapy which includes application of an ACMF for 15 min. Specifically, DOX:TXL-MMNPs are more effective than DOX:Cis-Pt-MMNPs towards the PC3 cell line. The internalization of multiple drug loaded MMNPs by cells and their morphological changes due to thermo-chemotherapy are confirmed through confocal microscopy. From the present results, it is observed that the DOX:TXL and DOX:Cis-Pt conjugated MMNPs, under an ACMF, can readily minimize drug resistance. This has significantly enhanced the cell apoptosis of target cancer cells.

Abstract
Superparamagnetic iron oxide nanoparticles (SPIONs) have been prepared and coated with positively (-NH3(+)) and negatively (-COO(-)) charged shells. These NPs, as well as their "bare" precursor, which actually contain surface hydroxyl groups, have been characterized in vitro, and their influence on a human epithelial cell line has been assessed in terms of cell metabolic activity, cellular membrane lysis, mitochondrial activity, and reactive oxygen species production. Their physicochemical characterizations and protein-nanoparticle interactions have been determined using dynamic light scattering, high-resolution transmission electron microscopy, matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) spectrometry, and Coomassie Blue fast staining. Cell-SPION interactions have been determined by PrestoBlue resazurin-based, Trypan Blue dye exclusion-based, and MTS cell proliferation assays as well as by reactive oxygen species determination. The results show that different surface characteristics cause different protein corona and cell responses. Some proteins (e.g., albumin) are adsorbed only on positively charged coatings and others (e.g., fibrinogen) only on negatively charged coating. No cell deaths occur, but cell proliferation is influenced by surface chemistry. Proliferation reduction is dose dependent and highest for bare SPIONs. Negatively charged SPIONs were the most biocompatible.

Abstract
Food defense requires the means to efficiently screen large volumes of food for microbial pathogens. Even rapid detection methods often require lengthy enrichment steps, making them impractical for this application. There is a great need for rapid, sensitive, specific, and inexpensive methods for extracting and concentrating microbial pathogens from food. In this study, an immuno-magnetic separation (IMS) methodology was developed for Escherichia coli O157:H7, using electrically active magnetic nanoparticles (EAMNPs). The analytical specificity of the IMS method was evaluated against Escherichia coli O55:H7 and Shigella boydii, and was improved over previous protocols by the addition of sodium chloride during the conjugation of antibodies onto MNPs. The analytical sensitivity of the IMS method was greatest when a high concentration of antibodies (1.0 mg/mL) was present during conjugation. EAMNP concentrations of 1.0 and 0.5 mg/mL provided optimal analytical sensitivity and analytical specificity. The entire IMS procedure requires only 35 min, and antibody-conjugated MNPs show no decline in performance up to 149 days after conjugation. This analytically sensitive and specific extraction protocol has excellent longevity and shows promise as an effective extraction for multiple electrochemical biosensor applications.

Abstract
Despite the complexities of cancer, remarkable diagnostic and therapeutic advances have been made during the past decade, which include improved genetic, molecular, and nanoscale understanding of the disease. Physical science and engineering, and nanotechnology in particular, have contributed to these developments through out-of-the-box ideas and initiatives from perspectives that are far removed from classical biological and medicinal aspects of cancer. Nanostructures, in particular, are being effectively utilized in sensing/diagnostics of cancer while nanoscale carriers are able to deliver therapeutic cargo for timed and controlled release at localized tumor sites. Magnetic nanostructures (MNS) have especially attracted considerable attention of researchers to address cancer diagnostics and therapy. A significant part of the promise of MNS lies in their potential for "theranostic" applications, wherein diagnostics makes use of the enhanced localized contrast in magnetic resonance imaging (MRI) while therapy leverages the ability of MNS to heat under external radio frequency (RF) field for thermal therapy or use of thermal activation for release of therapy cargo. In this chapter, we report some of the key developments in recent years in regard to MNS as potential theranostic carriers. We describe that the r₂relaxivity of MNS can be maximized by allowing water (proton) diffusion in the vicinity of MNS by polyethylene glycol (PEG) anchoring, which also facilitates excellent fluidic stability in various media and extended in vivo circulation while maintaining high r₂values needed for T₂-weighted MRI contrast. Further, the specific absorption rate (SAR) required for thermal activation of MNS can be tailored by controlling composition and size of MNS. Together, emerging MNS show considerable promise to realize theranostic potential. We discuss that properly functionalized MNS can be designed to provide remarkable in vivo stability and accompanying pharmacokinetics exhibit organ localization that can be tailored for specific applications. In this context, even iron-based MNS show extended circulation as well as diverse organ accumulation beyond liver, which otherwise renders MNS potentially toxic to liver function. We believe that MNS, including those based on iron oxides, have entered a renaissance era where intelligent synthesis, functionalization, stabilization, and targeting provide ample evidence for applications in localized cancer theranostics.

Abstract
One way to image the molecular pathology in Alzheimer's disease is by positron emission tomography using probes that target amyloid fibrils. However, these fibrils are not closely linked to the development of the disease. It is now thought that early-stage biomarkers that instigate memory loss are composed of Aβ oligomers. Here, we report a sensitive molecular magnetic resonance imaging contrast probe that is specific for Aβ oligomers. We attach oligomer-specific antibodies onto magnetic nanostructures and show that the complex is stable and binds to Aβ oligomers on cells and brain tissues to give a magnetic resonance imaging signal. When intranasally administered to an Alzheimer's disease mouse model, the probe readily reached hippocampal Aβ oligomers. In isolated samples of human brain tissue, we observed a magnetic resonance imaging signal that distinguished Alzheimer's disease from controls. Such nanostructures that target neurotoxic Aβ oligomers are potentially useful for evaluating the efficacy of new drugs and ultimately for early-stage Alzheimer's disease diagnosis and disease management.

Abstract
Superparamagnetic iron oxide nanoparticles (SPIONs) can generate heat when subjected to an alternating magnetic field (AMF). In the European Union, SPIONs actuated by AMF are used in hyperthermia treatment of glioblastoma multiforme, an aggressive form of brain cancer. Current data from clinical trials suggest that this therapy improves patient life expectancy, but their effect on healthy brain cells is virtually unknown. Thus, a viability study involving SPIONs subjected to an AMF was carried out on healthy cortical rat astrocytes, the most abundant cell type in the mammalian brain. The cells were cultured with aminosilane- or starch-coated SPIONs with or without application of an AMF. Significant cell death (p < 0.05) was observed only when SPIONs were added to astrocyte cultures and subjected to an AMF. Unexpectedly, the decrease in astrocyte viability was observed at physiological temperatures (34-40 °C) with AMF. A further decrease in astrocyte viability was found only when bulk temperatures exceeded 45 °C. To discern differences in the astrocyte structure when astrocytes were cultured with particles with or without AMF, scanning electron microscopy (SEM) was performed. SEM images revealed a change in the structure of the astrocyte cell membrane only when astrocytes were cultured with SPIONs and actuated with an AMF. This study is the first to report that astrocyte death occurs at physiological temperatures in the presence of magnetic particles and AMF, suggesting that other mechanisms are responsible for inducing astrocyte death in addition to heat.

Abstract
A new pH-sensitive and thermosensitive dual drug delivery system consisting of thin lipid layer encapsulated mesoporous magnetite nanoassemblies (MMNA) has been developed which can deliver two anticancer drugs simultaneously. The formulation of lipid layer used is 5:2:2:2 w/w, DPPC:cholesterol:DSPE-PEG2000:MMNA. The structure, morphology and magnetic properties of MMNA and lipid coated MMNA (LMMNA) were thoroughly characterized. This hybrid system was investigated for its ability to carry two anticancer drugs as well as its ability to provide heat under an alternating current magnetic field (ACMF). A very high loading efficiency of up to ∼81% of doxorubicin hydrochloride (DOX) with an ∼0.02 mg mg(-1) loading capacity and ∼60% of paclitaxel (TXL) with an ∼0.03 mg mg(-1) loading capacity are obtained with LMMNA. A sustained release of drug is observed over a period of 172 h, with better release, of ∼88:53% (DOX:TXL), at pH 4.3 compared to the ∼28:26% (DOX:TXL) in physiological conditions (pH 7.4). An enhanced release of ∼72 and ∼68% is recorded for DOX and TXL, respectively, during the first hour with the application of an ACMF (∼43°C). A greater in vitro cytotoxic effect is observed with the two drugs compared to them individually in HeLa, MCF-7 and HepG2 cancer cells. With the application of an ACMF for 10 min, the cell killing efficiency is improved substantially due to simultaneous thermo- and chemotherapy. Confocal microscopy confirms the internalization of drug loaded MMNA and LMMNA by cells and their morphological changes during thermochemotherapy.

Abstract
Magnetic nanoparticles (MNPs) bear many intriguing properties such as superparamagnetism, high specific surface area, remarkable colloidal stability and biocompatibility, which evoke great interest and desire of exploration in biomedical applications. For the use in the complicated physiological environment, MNPs are still being developed to have the enhanced performances and down-to-earth practicality. Engineering of MNPs into hierarchical structures is thus proposed to create a new family of magnetic materials, magnetic colloidal supraparticles (MCSPs), which exhibit collective properties and unique nanomaterial characters. From a biomedical point of view, applicability of MCSPs is somewhat more distinctive in contrast to their primary MNPs, because MCSPs are amenable to modulation of secondary structure, promotion of magnetic responsiveness and ease of function design. As a result, MCSPs have been subject to intense researches in recent years, with the aim to develop outstanding composite materials for biomedical applications. In this review, we embark on an overview of foundational topics that detail the design and fabrication of MCSPs by evaporation-induced emulsion and solvothermal techniques, and continue with a guideline for modification of MCSPs with inorganic oxides and organic polymers. Particular focus is then placed on the biomedical applications of modified MCSPs. Many examples illustrate the latest progress in design of MCSP-based microspheres for magnetic resonance imaging, targeted drug delivery, sensing, and harvesting of peptides/proteins. After these detailed accounts, the current challenges and future development of researches and applications are discussed as a conclusion to the review.

Abstract
We demonstrate a single-step facile approach for the synthesis of glycine (amino acid) passivated Fe(3)O(4) magnetic nanoparticles (GMNPs) using soft chemical route. The surface passivation of Fe(3)O(4) nanoparticles with glycine molecules was evident from infrared spectroscopy, thermal and elemental analyses, and light scattering measurements. These nanoparticles show better colloidal stability, good magnetization, excellent self-heating capacity under external AC magnetic field and cytocompatibility with cell lines. Further, the active functional groups (-NH(2)) present on the surface of Fe(3)O(4) nanoparticles can be accessible for routine conjugation of biomolecules/biolabelling through well-developed bioconjugation chemistry. Specifically, a new colloidal glycine passivated biocompatible Fe(3)O(4) nanoparticles with excellent specific absorption rate (SAR) have been fabricated, which can be used as an effective heating source for hyperthermia treatment of cancer (thermal therapy).

Abstract
Specific bioprobes for single photon emission computed tomography (SPECT) and magnetic resonance imaging (MRI) have enormous potential for use in cancer imaging in near-future clinical settings. The authors describe the development of dual modality molecular imaging bioprobes, in the form of magnetic nanoparticles (NPs) conjugated to antibodies, for SPECT and MRI of mesothelin-expressing cancers. The bioprobes were developed by conjugating (111)In labeled antimesothelin antibody mAbMB to superparamagnetic iron oxide NPs. Our experimental findings provide evidence that such bioprobes retain their magnetic properties as well as the ability to specifically localize in mesothelin-expressing tumors. It is anticipated that combining SPECT with MR will help obtain both functional and anatomical imaging information with high signal sensitivity and contrast, thereby providing a powerful diagnostic tool for early diagnosis and treatment planning of mesothelin-expressing cancers.

Abstract
The research on biomedical applications of nanoparticles has seen an upsurge in recent years due to their unique capabilities in treatment of ailments. Though there are ample reviews on the advances of nanoparticles right from their fabrication to applications, comparatively fewer reviews are available for the nanostructured materials particularly on oxides and hybrids. These materials possess unique physicochemical properties with an ability to get functionalized at molecular and cellular level for biochemical interactions. Keeping the enormosity of the nanostructures in mind, we intend to cover only the recent and most noteworthy developments in this area. We, particularly emphasize on iron oxide and its derivatives, zinc oxides, layered double hydroxides, silica and binary/ternary metal oxides and their applications in the area of therapeutics. This review also focuses on the designing of biodegradable and biocompatible nanocarriers and critical issues related to their therapeutic applications. Several representative examples discuss targeting strategies and stimuli responsive nanocarriers and their therapeutics.

Abstract
The development of MRI contrast agents has experienced its version of the gilded age over the past decade, thanks largely to the rapid advances in nanotechnology. In addition to progress in single mode contrast agents, which ushered in unprecedented R(1) or R(2) sensitivities, there has also been a boon in the development of agents covering more than one mode of detection. These include T(1)-PET, T(2)-PET T(1)-optical, T(2)-optical, T(1)-T(2) agents and many others. In this review, we describe four areas which we feel have experienced particular growth due to nanotechnology, specifically T(2) magnetic nanostructure development, T(1)/T(2)-optical dual mode agents, and most recently the T(1)-T(2) hybrid imaging systems. In each of these systems, we describe applications including in vitro, in vivo usage and assay development. In all, while the benefits and drawbacks of most MRI contrast agents depend on the application at hand, the recent development in multimodal nanohybrids may curtail the shortcomings of single mode agents in diagnostic and clinical settings by synergistically incorporating functionality. It is hoped that as nanotechnology advances over the next decade, it will produce agents with increased diagnostics and assay relevant capabilities in streamlined packages that can meaningfully improve patient care and prognostics. In this review article, we focus on T(2) materials, its surface functionalization and coupling with optical and/or T(1) agents.

Abstract
Surface engineered magnetic nanoparticles (Fe(3)O(4)) were synthesized by facile soft-chemical approaches. XRD and TEM analyses reveal the formation of single-phase Fe(3)O(4) inverse spinel nanostructures. The functionalization of Fe(3)O(4) nanoparticles with carboxyl (succinic acid), amine (ethylenediamine) and thiol (2,3-dimercaptosuccinic acid) were evident from FTIR spectra, elemental analysis and zeta-potential measurements. From TEM micrographs, it has been observed that nanoparticles of average sizes about 10 and 6 nm are formed in carboxyl and thiol functionalized Fe(3)O(4), respectively. However, each amine functionalized Fe(3)O(4) is of size ~40 nm comprising numerous nanoparticles of average diameter 6 nm. These nanoparticles show superparamagnetic behavior at room temperature with strong field dependent magnetic responsivity. We have explored the efficiency of these nanoparticles for removal of toxic metal ions (Cr(3+), Co(2+), Ni(2+), Cu(2+), Cd(2+), Pb(2+) and As(3+)) and bacterial pathogens (Escherichia coli) from water. Depending upon the surface functionality (COOH, NH(2) or SH), magnetic nanoadsorbents capture metal ions either by forming chelate complexes or ion exchange process or electrostatic interaction. It has been observed that the capture efficiency of bacteria is strongly dependent on the concentration of nanoadsorbents and their inoculation time. Furthermore, these nanoadsorbents can be used as highly efficient separable and reusable materials for removal of toxic metal ions.

Abstract
The synthesis and characterization of amino-functionalized magnetic nanoparticles (amino-MNPs) were carried out. Amino-MNPs were prepared using polyol technique in an autoclave (121°C) without inert gas. The characterization of particles employed conventional SEM-EDS, TEM, XRD, FTIR, and VSM techniques. Results showed that amount of NaOH affected to the speed of MNP formation. The desirable uniform cubic shape of amino-MNPs was obtained from the addition of 2.50% w/v NaOH for 3 reaction cycles (2 hours/cycle). The amino-MNPs obtained from this condition have cubic shapes with the average size of 43 ± 9 nm. Results from elemental and structure analyses confirmed that the product was pure magnetite. The magnetic properties were ferromagnetism and were very close to a complete superparamagnetism. Fourier transform infrared (FT-IR) spectrum showed that the amino group existed on particle surface. The amino-MNPs of cubic shape were synthesized with facile single step at low temperature, and they have potential to be used for rapid microbial detection and many biological applications.

Abstract
This article demonstrates the encapsulation of cubic iron oxide nanoparticles (NPs) by Brome mosaic virus capsid shells and the formation, for the first time, of virus-based nanoparticles (VNPs) with cubic cores. Cubic iron oxide NPs functionalized with phospholipids containing poly(ethylene glycol) tails and terminal carboxyl groups exhibited exceptional relaxivity in magnetic resonance imaging experiments, which opens the way for in vivo MRI studies of systemic virus movement in plants. Preliminary data on cell-to-cell and long-distance transit behavior of cubic iron oxide NPs and VNPs in Nicotiana benthamiana leaves indicate that VNPs have specific transit properties, i.e., penetration into tissue and long-distance transfer through the vasculature in N. benthamiana plants, even at low temperature (6 °C), while NPs devoid of virus protein coats exhibit limited transport by comparison. These particles potentially open new opportunities for high-contrast functional imaging in plants and for the delivery of therapeutic antimicrobial cores into plants.

Abstract
In this paper, we report the influence of reaction conditions and the chain length on the nanoparticle (NP) size and morphology for thermal decomposition of long-chain iron carboxylates such as Fe(III) oleate, palmitate, and myristate. In the majority of cases, spherical NPs are obtained; however, nonspherical morphologies were observed in some "extreme" conditions. For example, iron oxide nanostars are formed in eicosane at the Fe oleate/oleic acid ratio of 0.49 g/mL: the highest oleic acid content when NPs still form. The cubic NPs with flat facets are obtained by decomposition of iron palmitate at the lowest palmitic acid fractions, but the most monodisperse cubes are formed at the Fe palmitate/palmitic acid ratio of 1.19 g/mL. Elliptical NPs are formed from Fe myristate with the most well-defined structure. Easy transformation of these NPs from wüstite to maghemite without aggregation and loss of solubility makes them excellent candidates for biomedical applications after proper functionalization described in our preceding papers.

Abstract
Magnetic resonance imaging (MRI) has become a powerful technique in biological molecular imaging and clinical diagnosis. With the rapid progress in nanoscale science and technology, nanostructure-based MR contrast agents are undergoing rapid development. This is in part due to the tuneable magnetic and cellular uptake properties, large surface area for conjugation and favourable biodistribution. In this review, we describe our recent progress in the development of high-performance nanostructured MR contrast agents. Specifically, we report on Gd-enriched nanostructured probes that exhibit T(1) MR contrast and superparamagnetic Fe(3)O(4) and CoFe(2)O(4) nanostructures that display T(2) MR contrast enhancement. The effects of nanostructure size, shape, assembly and surface modification on relaxivity are described. The potential of these contrast agents for in vitro and in vivo MR imaging with respect to colloidal stability under physiological conditions, biocompatibility, and surface functionality are also evaluated.

Thermal behavior of magnetically modalized poly(N-isopropylacrylamide)-chitosan based nanohydrogel. Colloids Surf B Biointerfaces 2010; 81:185-94. [PMID: 20702074 DOI: 10.1016/j.colsurfb.2010.07.009] [Citation(s) in RCA: 90] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2009] [Revised: 05/01/2010] [Accepted: 07/05/2010] [Indexed: 11/23/2022]
Abstract
Poly(NIPAAm)-CS based nanohydrogels (NHGs) and iron oxide (Fe(3)O(4)) magnetic nanoparticles encapsulated magnetic nanohydrogels (MNHGs) were synthesized by free radical polymerization of N-isopropylacrylamide (NIPAAm) at 60 degrees C in presence of chitosan (CS) in different feed ratios. The polymerization of NIPAAm and the presence of CS as well as Fe(3)O(4) in hydrogels were confirmed from Fourier transform infrared (FTIR) spectra and X-ray diffraction (XRD), respectively. (13)C solid state nuclear magnetic resonance (NMR) spectra clearly revealed the grafting of CS into poly(NIPAAm). The scanning electron microscopy (SEM) and atomic force microscopy (AFM) images showed the formation of spherical shaped NHGs of different sizes ranging from 50 nm to 200 nm depending upon the feed ratios of CS and NIPAAm, which was further supported by mean hydrodynamic diameter measured by dynamic light scattering (DLS). It has been observed that CS not only served as a cross linker during polymerization but also plays a critical role in controlling the growth of NHG and enhancement in lower critical solution temperature (LCST). The encapsulation of Fe(3)O(4) nanoparticles (10-12 nm) into NHGs ( approximately 200 nm) was confirmed by transmission electron microscopy (TEM) and further corroborated with magnetic force microscopy (MFM) image. The LCST of poly(NIPAAm) was found to increase with increasing weight ratio of CS to NIPAAm. Furthermore, the encapsulation of iron oxide nanoparticles into hydrogels also caused an increment in LCST. Specifically, temperature optimized NHG and MNHG were fabricated having LCST close to 42 degrees C (hyperthermia temperature). The MNHG shows optimal magnetization, good specific absorption rate (under external AC magnetic field) and excellent cytocompatibility with L929 cell lines, which may find potential applications in hyperthermia treatment of cancer and targeted drug delivery.
