Drug delivery for a long time has been a major problem in the pharmaceutical field. The development of a new Nano-carrier system called nanosponge has shown the potential to solve the problem. Nanosponge has a porous structure and can entrap the drug in it. It can carry both hydrophilic and hydrophobic drugs. They also provide controlled release of the drugs and can also protect various substances from degradation. Nanosponge can increase the solubility of drugs and can also be formulated into an oral, topical and parenteral dosage form. The current review explores different preparation techniques, characterization parameters, as well as various applications of nanosponge. Various patents related to nanosponge drug delivery system have been discussed in this study.

长期以来，药物递送一直是制药领域的一大难题。一种称为纳米海绵的新型纳米载体系统的开发已显示出解决该问题的潜力。纳米海绵具有多孔结构，可以将药物包裹在其中。它可以携带亲水性和疏水性药物。它们还提供药物的受控释放，还可以保护各种物质免于降解。纳米海绵可以增加药物的溶解度，也可以配制成口服、外用和肠胃外剂型。本综述探讨了纳米海绵的不同制备技术、表征参数以及各种应用。本研究讨论了与纳米海绵给药系统相关的各种专利。
