Ferromagnetic gamma-Fe(2)O(3)/polyrhodanine nanoparticles with average diameters of ca. 10 nm were prepared by a one-step synthetic procedure and applied as a recyclable antibacterial agent towards Gram-negative/positive bacteria.
Environmentally benign aerobic oxidation of alcohols to methyl esters catalyzed by polymer-incarcerated gold nanoclusters (PI-Au) was developed and reactions proceeded under very mild conditions. The catalyst could be recovered by simple operations without significant loss of activity.
This chapter describes the application of gold nanorods in biomedical imaging and photothermal therapy. The photothermal properties of gold nanorods are summarized and the synthesis as well as antibody conjugation of gold nanorods is outlined. Biomedical applications of gold nanorods include cancer imaging using their…
The aim of the study was to synthesize silver nanoparticles by using filamentous fungus Penicillium sp. The fungal culture was isolated from the soil samples collected from agriculture fields in Vellore district, Tamil Nadu, India. The purified fungal isolates were inoculated in minimal medium and incubated at room te…
Gold nanoparticles supported on cerium(IV) oxide powder showed strong absorption at around 550 nm due to localized surface plasmon resonance of Au and exhibited a higher level of activity than other Au-supporting samples in mineralization of organic acids in aqueous suspensions under irradiation of visible light (> ca…
We present unusual microstructures formed by patchy metallodielectric particles under high frequency alternating current (AC) electric fields. These particles assemble into two-directional percolated networks and lattices of unusual symmetry by interactions pre-programmed by their patch size and orientation. Electrost…
Amorphous SnO thin films were prepared on quartz and 190 nm substrates by electron beam evaporation. X-ray diffraction results reveal that amorphous SnO transforms into polycrystalline (tetragonal litharge structure) after rapid thermal annealing in Ar ambient at and starts decomposing into (orthorhombic structure) wi…
This review of structurally simple and essentially molecular metal clusters on solid supports addresses synthesis, characterization, reactivity, and catalysis. Examples of supported clusters made in high yields are Os(3), Ir(4), Ir(6), and Rh(6), and typical supports are MgO, gamma-Al(2)O(3), and zeolites. Supported c…
Series of biodegradable polyesters poly(butylene adipate) (PBA), poly(butylene succinate) (PBS), and poly(butylene adipate‐co‐butylene terephthalate) (PBAT) were synthesized successfully by melt polycondensation. The polyesters were characterized by Fourier transform infrared spectroscopy (FTIR), , differential scanni…
The modified sol–gel approach to the synthesis of well-structured magnetic mesoporous silica nanoparticles (M-MSNs) was described, which comprised magnetic nanoparticles resided within the mesoporous nanoparticles. A diversity of surface modification was subjected to systematic investigation using organic silanes, eve…
We report the synthesis and in vitro evaluation of folate receptor-targeted nanoconjugate that releases its therapeutic payload via a photochemical mechanism.
We developed microfluidic-based pure chitosan microfibers (approximately 1 meter long, 70-150 microm diameter) for liver tissue engineering applications. Despite the potential of the chitosan for creating bio-artificial liver chips, its major limitation is the inability to fabricate pure chitosan-based microstructures…
The synthetic engineering of anionic polyoxometalate (POM) clusters with predefined properties tailored to specific applications is a great challenge using routine "one-pot" POM syntheses. Under such conditions, difficulties often arise from the multitude of complex reaction pathways and self-assembly processes occurr…
The phase stability and mechanical properties of tungsten borides W(2)B, WB, WB(2), W(2)B(5) and WB(4) were extensively studied by first-principles calculations within density functional theory. The thermodynamic and mechanical stabilities were examined. Our calculations on the enthalpy-pressure relationship and conve…
We demonstrate a high yield method of functionalizing graphene nanosheets through nitrene addition of azido-phenylalanine [Phe(N(3))] to exfoliated micro-crystalline graphite (microG). This method provides a direct route to highly functionalized graphene sheets. TEM analysis of the product shows few layer (n < 5) grap…
Over the years, biological imaging has seen many advances, allowing scientists to unfold many of the mysteries surrounding biological processes. The ideal imaging resolution would be in nanometres, as most biological processes occur at this scale. Nanotechnology has made this possible with functionalised nanoparticles…
Through direct absorption of microwave irradiation by GO film, we developed a rapid, dry approach to synthesize reduced graphene.
Hollow and porous silver microspheres are synthesized using bacteria as template. They have been proven to be excellent SERS substrate.
A water-insoluble photocatalyst constructed from Wells-Dawson polyoxometalates and hexacopper phosphates has been prepared, exhibiting good photocatalytic activity in the presence of H(2)O(2) under visible light irradiation.
The need for advanced materials in emerging technologies such as tissue engineering has prompted increased research to produce novel biodegradable polymers elastic in nature and mechanically compliant with the host tissue. We have developed a soft biodegradable elastomeric platform biomaterial created from citric acid…
