Mesoporous silica nanoparticles grafted with light-responsive polymer on the outer surface were developed as novel nanogated ensembles, which allow encapsulation and release of drug and biological molecules under light irradiation.
Core-shell silica nanoparticles comprised of a RuBpy doped silica core and a Pas-DTPA doped silica shell were synthesized and post-functionalized with an encoding fluorescence combination and multiplex imaging function.
Single-walled carbon nanotube (SWCNT) transparent conducting films (TCFs) were fabricated for the electrodes of organic light-emitting diodes (OLEDs); three types of film were studied. The as-prepared SWCNT TCFs displayed a relatively low sheet resistance of 82.6 Ω/sq at 80.7 T% with a relatively large surface roughness of 30 nm. The TCFs were top-coated… (More)
We report a molecule-scale controlled-release system based on silica nanoparticles bearing a photoactive o-nitrobenzyl bromide linkage, which allows cage and release of drug or biologically active molecules by light.
Reduced graphene oxide (RGO) is modified with 1,1'-dimethyl-4,4'-bipyridinium dichloride (methyl viologen, i.e. MV) by a π-π interaction, and further used as support for immobilization of Pt nanoparticles to prepare a Pt/MV-RGO catalyst for direct methanol fuel cells. Transmission electron microscopy, X-ray powder diffraction, Raman spectroscopy and X-ray… (More)
UV light irradiation triggers Au NPs that are respectively functionalized on the surface by o-nitrobenzyl alcohol and benzylamine to proceed with a covalent ligation reaction, which leads to assembling of Au NPs into anisotropic one-dimensional (1D) arrays in aqueous solution via indazolone linkages.
