Nanosponges: A Novel Class of Drug Delivery System

Nanosponges are a novel class of materials consisting of microscopic sponge-like structures with narrow cavities that are a few nanometers in diameter.Nanosponges are solid porous particles that can load drugs and other active chemicals into their nanocavity.They can be topical, parenteral, oral, or inhaled.Nanosponges, which are about the size of viruses, can hold many drugs.These tiny sponges can move through the body until they reach the target, stick to the surface, and release the medication in a controlled and predictable manner.Recent interest in these materials stems from their potential in medication delivery, cancer therapy, and other biomedical sectors.Polymers, copolymers, and cross-linkers can be used to manufacture nanosponges with therapeutically tuned characteristics.They improve bioavailability, solubility, and sustained release of weakly water-soluble medicines.Nanosponges can also target cancer cells and deliver medications selectively.Nanosponges are diverse platforms for drug delivery and other biomedical applications, as shown in this review.
