A water-in-oil microemulsion method has been applied for the preparation of silica-coated iron oxide nanoparticles. Three different nonionic surfactants (Triton X-100, Igepal CO-520, and Brij-97) have used microemulsions, their effects on particle size, crystallinity, magnetic properties studied. The nanoparticles are formed by coprecipitation reaction ferrous ferric salts with inorganic bases. strong base, NaOH, a comparatively mild NH4OH, in each surfactant to observe whether basicity some...
A new molecular conjugation method has been developed to label biomolecules with optically stable metalorganic luminophores, such as tris(2,2'-bipyridyl)dichlororuthenium(II) hexahydrate (Rubpy), which are otherwise not possible for direct linking the biomolecules. Unique biochemical properties of biomolecule can, thus, be associated photostable luminophores. This opens a general way conjugate desired using sensitive signal transduction method. It also promotes application excellent...
The <i>Journal of Biomedical Optics</i> (JBO) is a Gold Open Access journal that publishes peer-reviewed papers on the use novel optical systems and techniques for improved health care biomedical research.
Water-in-oil (w/o) microemulsion synthesis of 70 nm size monodisperse TAT (a cell penetrating peptide, CPP) conjugated, FITC (fluorescein isothiocyanate) doped silica nanoparticles (TAT-FSNPs) is reported; human lung adenocarcinoma (A549) cells (in vitro) and rat brain tissue vivo) were successfully labeled using TAT-FSNPs.
In the last decade, field of nanoparticle (NP) technology has attracted immense interest in bioimaging and biosensing research. This demonstrated its capability obtaining sensitive data a noninvasive manner, promising breakthrough early-stage cancer diagnosis, stem cell tracking, drug delivery, pathogen detection gene delivery near future. However, successful wide application this relies greatly on robust NP engineering synthesis methodologies. The development steps involve design,...
Multimodal Gold-speckled silica nanoparticles as contrast agents for noninvasive imaging with magnetic resonance and photoacoustic tomography have been prepared in a simple one-pot synthesis using nonionic microemulsions. Magnetic is provided through gadolinium incorporated the matrix, whereas signal originates from nonuniform, discontinuous gold nanodomains speckled across surface.
A simple and straightforward route for the synthesis of thioethers, thioesters, vinyl thioethers thio-Michael adducts has been demonstrated using silica nanoparticles (NPs) as a reusable catalyst via 1,2-addition thiols to alkenes, alkynes alkyl/acyl halides, 1,4-addition conjugated alkenes at room temperature.
Environmental contextThere are great concerns around current wide usage of copper-based agrochemicals. We compare the fate nano- and conventional forms copper, in particular their resistance to wash-off by rain (rainfastness), following application citrus leaves. Results showing large differences between formulations amount copper washed from leaves provide essential information optimise agrochemical efficacy while minimising environmental impact. AbstractThis study compares rainfastness...
Nanoscale nutrients are promising for improving crop performance.
Proximal posterior inferior cerebellar artery (PICA) aneurysms represent a subset of circulation that can be routinely treated with either clipping or coiling. The literature contains limited numbers patients proximal PICA endovascular surgery. We report our experience surgery emphasis on poor Hunt-Hess grades.We reviewed 31 consecutive who were following data analyzed: age, sex, size aneurysm, grade at presentation, Fisher angiographic result after embolization, complications, number days...
High-aspect ratio Cd1−xZnxS (x = 0−1) alloy semiconductor nanowires are reported here for the first time using an ethylenediamine (en)-assisted solvothermal approach. The composition of en−water (en-w) mixed solvent plays a crucial role in determining morphology and crystalline phase middle range x (i.e., when approaches 0.5). A transformation from hexagonal to cubic was observed en-dominated (en/w, 5:1). Nanowires with phases were formed entire increasing water content system 2:1). aspect...
A robust water-in-oil microemulsion method of making water-dispersible ultra-small (<30 nm) size fluorescent chitosan nanoparticles is reported for the first time and specific targeting these FCNPs to human leukemia cellsviaaptamer recognition demonstrated.
Synthesis of thin (5−8 nm) CdS−Mn/ZnS core−shell nanowires (CSNWs) with high aspect ratio (up to ∼150) is reported for the first time. The modified solvothermal synthesis CSNW involved two steps: formation Mn-doped CdS core followed by ZnS shell. growth process engineered in such a way that shell layer grew radially onto prematurely grown CdS−Mn core, is, prior its well-faceted surface.
Peripheral nerve injuries (PNI) impact millions of individuals in the United States, prompting thousands repair procedures annually. Nerve conduits (NC) are commonly utilized to treat under 3 cm but larger gaps still pose a challenge for successful peripheral regeneration (PNR) and functional recovery. This is partly attributed absence bioactive agents such as stem cells or growth factors FDA-approved due safety, harvesting, reproducibility concerns. Therefore, curcumin, phytochemical, has...
Highly luminescent and photostable CdS:Mn/ZnS core/shell quantum dots are not water soluble because of their hydrophobicity. To create water-soluble by an appropriate surface functionalization, synthesized in a water-in-oil (W/O) microemulsion system (reverse micelles) were consecutively overcoated with very thin silica layer ( approximately 2.5 nm thick) within the same reverse micellar system. The droplet serves as nanosized reactor for controlled hydrolysis condensation precursor,...
