Essential oils have important commercial applications as preservatives and flavours, and more recently as natural antimicrobial agents. These applications require a suitable formulation constituted by biodegradable compounds that protect the essential oil from degradation and evaporation at the same time that allows for a sustained release. Microcapsules of biopolymers loaded with essential oil...

In the present study, Chitosan microspheres containing Trospium chloride were prepared by coacervation phase separation method and characterized by optical microscopy and scanning electron microscopy. The microspheres were analyzed for drug entrapment, bulk density, angle of repose, particle size and In-vitro release pattern. The effect of process variables on microsphere size was studied and b...

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...

Probiotics are effective coadjuvancy against human affections. To confer their beneficial effects to humans, probiotics adhere and colonize the intestine. Then, they must survive gastrointestinal conditions (~108–1010 cfu/day). However, concentration dose produce effect reduced. Synbiotics combination of prebiotics, can increase probiotics. Microencapsulation is an efficient approach protect sy...
