Silk fibroin microspheres with photothermal nanocarrier encapsulation for anticancer drug delivery.

Controlled drug release systems are pivotal in optimizing therapeutic outcomes and mitigating side effects in treatment protocols. While traditional delivery vectors such as liposomes, micro/nanoparticles, and microspheres are effective, they often struggle with consistency in drug release rates. This study addresses these issues by integrating stimuli-responsive elements specifically magnetic, thermal, and pH-responsive components into drug delivery systems for precise control.
