Injectable material for targeted drug delivery

Nanotechnology "Pill Bot"

Texas A&M University reports (with a video) on developing a carrier system that can deliver medicines and biosensors to targeted areas of the body. It is made off a hydrogel (a biocompatible material that doesn’t trigger the immune response) embedded with porous microparticles made from clusters of calcium carbonate nanoparticles that are formed around a specific material to trap it inside. Once a drug or biosensor is trapped within such microsphere, multiple layers of polymers are wrapped around the particles, thus allowing for a precise and customizable control over how the microcapsule will release its contents when it interacts with its surrounding environment.
