Characterization of spray dried chitosan-TPP microparticles formed by two- and three-fluid nozzles
Original language description
Chitosan microparticles cross-linked by tri-polyphosphate (TPP) anions have been prepared by spray drying. Two different cross-linking methods have been employed ? ex-situ cross-linking whereby aqueous solution of cross-linked chitosan nanoparticles hasbeen spray-dried by a two-fluid nozzle, and a novel in-situ cross-linking method, whereby solutions of chitosan and TPP have been fed to a three-fluid nozzle and cross-linking occurred within individual droplets. The size and morphology of the resultingmicroparticles have been characterised and their dependence on the cross-linking ratio and the initial chitosan concentration determined. Particles produced by the three-fluid nozzle were found to have favourable properties in terms of stability in aqueous media and they allow the use of higher chitosan concentrations, which makes them suitable for microencapsulation applications.
