Biopolymers are usually used in encapsulation techniques to protect natural products from degradation. The essential oil of Hedychium coronarium presents a floral scent, which justifies its use perfumes, addition, antimicrobial activity may contribute stability as protectant. Thus, this work aims investigate the extraction by steam distillation and enhance physicochemical through polycaprolacto...

These methods describe how to formulate injectable, supramolecular polymer-nanoparticle (PNP) hydrogels for use as biomaterials. PNP are composed of two components: hydrophobically modified cellulose the network polymer and self-assembled core-shell nanoparticles that act non-covalent cross linkers through dynamic, multivalent interactions. both formation these nanoprecipitation well formulatio...

A review of the state of knowledge on nanocapsules prepared from preformed polymers as active substances carriers is presented. This entails a general review of the different preparation methods: nanoprecipitation, emulsion-diffusion, double emulsification, emulsion-coacervation, polymer-coating and layer-by-layer, from the point of view of the methodological and mechanistic aspects involved, e...

Sorafenib-incoporated nanoparticles were prepared using a block copolymer that is composed of dextran and poly(DL-lactide-co-glycolide) [DexbLG] for antitumor drug delivery. Sorafenib-incorporated nanoparticles were prepared by a nanoprecipitation-dialysis method. Sorafenib-incorporated DexbLG nanoparticles were uniformly distributed in an aqueous solution regardless of the content of sorafenib...
