Chitosan microspheres
WebMar 29, 2000 · The chitosan microspheres were obtained with a “suspension crosslinking technique” in the size range of 30–700 μm. The stirring rate of the suspension medium and the chitosan/acetic acid ratio, emulsifier, and crosslinker, that is, the glutaraldehyde concentration in the suspension medium, were evaluated as the effective parameters on ... WebMethotrexate (MTX) loaded chitosan and chitin microspheres were prepared. The physicochemical characteristics were affected by various parameters, e.g. stirring speed, concentration of chitosan and chitin. The t(1/2) for in vitro release varied depending on the concentration of chitosan and chitin and the amount of glutaraldehyde used.
