Nanosponges: A Novel Approach of Drug Delivery System

Researchers often encounter a significant challenge when it comes to making sure that drugs reach their intended target without impacting other areas of the body. Fortunately, this issue can be tackled by creating innovative colloidal carriers known as nanosponges. These cutting-edge nanocarriers enable the precise and controlled delivery of both topical and systemic medications. Nanosponges are tiny, sponge-like particles, measuring less than 1 µm in diameter—roughly the size of a virus. Their small and highly porous structure allows them to encapsulate drugs that typically struggle with solubility, thereby boosting their bioavailability. Once they’re in the body, nanosponges circulate and specifically interact with target tissues, releasing the drug in a steady and controlled way. They can be produced using various methods, including sonication, ultrasound-assisted preparation, solvent diffusion, melt method, and solvent evaporation. All in all, nanosponges offer an effective, site-specific drug delivery system that minimizes side effects and improves solubility compared to traditional nanocarriers.
