Electrically controlled release of insulin using polypyrrole nanoparticles

Hydroxypropyl Starch Nanoparticles as Controlled Release

Hydroxypropyl starch was synthesized by modified sago starch with hydroxypropylation reaction. Hydroxypropyl starch nanoparticles with mean particle sizes of 110 nm are obtained by controlled precipitation through the drop-wise addition of dissolved hydroxypropyl starch solution into excess absolute ethanol. Piperine was loaded onto hydroxypropyl starch nanoparticles and native starch nanoparti...

Controlled release of singlet oxygen using diphenylanthracene functionalized polymer nanoparticles.

Functionalized polymer nanoparticles react and store molecular oxygen for several weeks in the form of endoperoxides. On-demand controlled release of singlet oxygen by the particles is achieved by thermolysis.

Electrically Controlled Release of Dopamine from Nanoporous Conducting Polymers

Multifunctional conducting fibres with electrically controlled release of ciprofloxacin.

We hereby present a new method of producing coaxial conducting polymer fibres loaded with an antibiotic drug that can then be subsequently released (or sustained) in response to electrical stimulation. The method involves wet-spinning of poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) fibre, which served as the inner core to the electropolymerised outer shell layer of polypy...

Hydrogel Nanoparticles with Thermally Controlled Drug Release

Improving the therapeutic efficacy and reducing systemic side effects of drugs is an important aspect in chemotherapy. The strategy presented here is the use of cisplatin loaded, temperature-sensitive, hydrogel nanoparticles (CisPt-NPs) and their ability to deliver and release chemodrugs selectively, based on thermal stimuli. The specially synthesized CisPt-NPs show a temperature-dependent incr...
