An Outlook towards Nanosponges: A Propitious Nanocarrier for Novel Drug Delivery

The nanotechnology sector is regarded as a developing technology due to its capacity to improve the already existing items and create new ones for a range of uses. The primary drivers of this expansion are cyclodextrin-based porous nanoparticles or distinctive nanosponges, which have lately been applied in the pharmaceutical, biomedical, and cosmetic industries. This superior technology can circumvent the defects of current techniques through its ability to attack and visualize tumor sites. The organization of this review article is such that we first looked at the distinctive characteristics of these nanosponges and the various synthesizing techniques, then about the drug loading and release principle and applications based on drug delivery, targeting, increasing the solubility of BCS Class II and IV drugs, other applications in biomedicine, and more. The most recent developments on the employment of biomimetic nanosponge as a pandemic tool because of the SARS-CoV-2 virus briefly align. Due to several significant limitations, effective targeted drug delivery systems have long been an aspiration. These issues might be resolved by the creation of new colloidal carriers termed Nanosponges.
