Achieving controlled drug release is one of the most significant challenges in pharmaceutical development. Utilizing polymer fibers allows for precise control over the rate and duration of drug release. By altering the fiber composition, porosity, and degradation rate, scientists can create systems that deliver drugs over days, weeks, or even months. Core-shell fibers, for example, can encapsulate a drug within a protective shell, releasing it only when the shell degrades or responds to a specific trigger, such as pH or temperature. This targeted delivery minimizes side effects and maximizes therapeutic efficacy. Further research into stimuli-responsive polymers is paving the way for even more sophisticated drug delivery systems.
