    tiny particles from crustacean shells used for targeted delivery

    Chitosan nanoparticles are tiny particles made from chitosan, a natural substance derived from the shells of crustaceans like shrimp and crabs. These nanoparticles are used in various fields, including medicine and cosmetics, because they can deliver drugs or other active ingredients directly to specific cells or tissues, enhancing their effectiveness and reducing side effects.
