Fabrication of Thermoresponsive Cross-Linked Poly(N-isopropylacrylamide) Nanocapsules and Silver Nanoparticle-Embedded Hybrid Capsules with Controlled Shell Thickness

Hollow polymeric nanocapsules have attracted great interest in recent years due to their broad applications in controlledrelease carriers, catalysis, nanoreactors, and encapsulation of guest molecules. Polymeric nanocapsules have been typically fabricated via the selfassembly of block copolymers, 5 polymerization within lipid vesicles, emulsion polymerization, 14 and the sacrificial core-templa...

Pluronic/chitosan shell cross-linked nanocapsules encapsulating magnetic nanoparticles.

We have developed novel Pluronic/chitosan nanocapsules encapsulating iron oxide nanoparticles. These nanocapsules were produced by dispersing hydrophobically-modified iron oxide nanoparticles and amine-reactive Pluronic derivatives in an organic solvent, and subsequently emulsification in an aqueous chitosan solution by ultrasonication. The resultant shell cross-linked nanocapsules had a unique...

Electrochemical fabrication of polypyrrole nanofibers and their characterization

Polypyrrole (PPy) nanofibers have been fabricated on glassy carbon electrode (GCE) usingelectrochemical technique. Electropolymerization of pyrrole (Py) for the fabrication of PPy nanofiberswas occurred on GCE by applying a fixed potential of about 0.85 V for 120 sec in a mild basic solutioncontaining sodium carbonate and sodium perchlorate. In the mild basic media, the monomer, Py, isoxidized ...
