A drug-delivery system that may distribute medications or vaccinations over the course of weeks or months has been created by bioengineers. The associated work was released in the journal Advanced Materials.Despite breakthroughs in medicine that can extend and enhance quality of life, about 50% of people with chronic diseases don’t take their medicines as directed. Up to 25% of hospital admissions and over 100,000 fatalities each year in the US are caused by this issue. Hence, strategies to improve treatment regimen adherence are essential for enhancing health outcomes.In the present study, researchers designed a new drug delivery system that enables drug release over several weeks. To do so, researchers used high-resolution 3D printing and soft lithography to produce arrays of over 300 tiny, nontoxic.
