Microscopic smart sponges know where and when to deliver a dose, and could potentially be used to treat a wide range of diseases.
Medical science is always hard at work developing the next miraculous medication, but some of them will be of limited use without an equally miraculous delivery system. Advanced materials science may hold the key to delivering drugs with high precision when an injection simply won’t do. Biomedical scientists and engineers at the University of North Carolina at Chapel Hill have joined forces looking for a breakthrough. What they’ve come up with is a so-called “smart sponge” that can be loaded up with medication, then release it only when and where it’s needed.
