Synthesis and Application of Polymeric Hydrogels for Drug Delivery

magine a tiny, squishy sponge that can carry medicine and release it exactly where and when it’s needed in the body. That’s essentially what polymeric hydrogels do! These fascinating materials, made from networks of polymer chains, have the unique ability to absorb large amounts of water while maintaining their structure. This makes them perfect for delivering drugs in a slow, controlled way—much better than a pill that releases everything at once.
