Preparation and Influencing Factors of Inner Asymmetric Structure Composite Microspheres

In situ preparation and protein delivery of silicate-alginate composite microspheres with core-shell structure.

The efficient loading and sustained release of proteins from bioactive microspheres remain a significant challenge. In this study, we have developed bioactive microspheres which can be loaded with protein and then have a controlled rate of protein release into a surrounding medium. This was achieved by preparing a bioactive microsphere system with core-shell structure, combining a calcium silic...

Preparation and Evaluation of Diphtheria Toxoid-Containing Microspheres

Preparation of chitosan (CS) microspheres as a novel drug delivery vehicle for intranasal immunization using high, medium and low CS molecular weight (MW) was investigated in this study. Diphtheria toxoid (DT) was used as a model antigen. The emulsion-solidification method was adopted for microencapsulation of DT.  In the first step, following the purification of semi-crude DT by the ion-exchan...
