Nano Sponges

The convenient and recent drug delivery system always likely to have some ideal and unique characters, particularly for safety, desired actions, accurate delivery, enrich with a therapeutic index with minimal adverse occurrence. In this regard, Nano sponges serve as a recent advance new drug delivery. Many researchers are attracted and concerned on Nano sponges presently. The present twofold objective of the review clarifies why Nano sponges are recent and advanced delivery system along with challenges related to solubility, stability and controlled release of Nano sponge and proven techniques to overcome. Since the nano-sized drug free carriers are recently formulated and suggested for drug delivery, which can be loaded with the numerous drugs, hence dealing with an appropriate technique for drug release is the need of the present time. This article states the most convenient method for drug release, and at concluding part gives awareness on recent work done and result obtained on Nano sponge worldwide along with the unique summary on the US granted patents for Nano sponges. Thus, a complete scenario on recent work, methods for evaluations, unique and multiple characters of Nano sponge has been discussed and summarized.
