The aim of this paper was to prepare chitosan microspheres characterised by a narrow dispersion of dimensions, suitable for application for drug delivery systems (DDS). The materials, unmodified as well as functionalised using polyethyleneimine were then used for encapsulation of drug-mimicking dyes. The polymeric beads were prepared by one stage process of membrane emulsification. The encapsulation...
Due to continued interest in biodegradable polymers, chitosan is one of the most commonly used polymers in the field of control release of active substances. Currently as carriers of drugs, among tablets, or micro spheres transdermal systems, called films, are used. The presented results apply to study a drug release in buffer of pH = 7.2 from chitosan film. To study the kinetics of controlled release...
