Microspheres are often hygroscopic, unstable, and stable at the same time
Microspheres Market The microspheres are often hygroscopic, unstable, and stable. They are also prone to recrystallization, therefore caution should be taken when choosing the initial ratio of acetylated dextran to methylprednisolone. Drug-loaded polymer microspheres are made using a technique called droplet microfluidics. The end product is a microsphere with consistent particle sizes and drug nanoparticles on the cross-sections. The prepared microspheres had a drug loading degree of 21.8-63.1 wt%, which is 40 to 450 times more than that achieved using conventional techniques. Additionally, in-droplet precipitation dramatically increased the effectiveness of drug loading. However, when the drug loading level increased, the encapsulation effectiveness declined. Microspheres' spherical shape has...
