With the advancement of technology and the evolution of modern healthcare systems, the focus is shifting from conventional drug delivery vehicles to novel, nanosized carriers. Nanogels are an example of such nanosized drug delivery systems that have been researched at length. They can be designed to be sensitive to a multitude of physical and chemical stimuli and this endows them with the capability to deliver the drugs they carry in a site-specific manner. These intelligent drug delivery systems are biocompatible and capable of loading copious quantities of the drug. pH is a major chemical property and temperature is a major physical property of a biological system. So nanogels responsive to either pH or temperature or a combination of both, possess immense biomedical potential. This review encompasses synthetic techniques and evaluation tests to confirm the responsiveness of single pH-responsive nanogels and thermoresponsive nanogels as well as dual pH/thermoresponsive nanogels. A closer look is also taken at their biomedical applications.
The emergence of nanotechnology paves the way for improving disease therapy strategies. An investigation into the progression of the release of the medication targeting the specified predetermined location is a significant factor to consider. Due to the ability to advance existing products and to develop new products in a variety of applications, the nanotechnology industry is considered an evolving technology. Cyclodextrin-based porous nanoparticles or unique nano-sponges (NSs) which have recently been used in the pharmaceutical, biomedical, and cosmetic industries are the main elements of this growth. This superior technology can circumvent the defects of current techniques by its ability to attack and visualize tumour sites. A biodegradable and biocompatible feature along with a built-in high surface area resulting in enormous amounts of drug loading and biomimetic design, and the ability to control nanoparticles size are just a handful of good attractive attributes that find this technique as an overwhelming advantage in the field of nanomedicine. This review article is organized such that we first explored the unique features of these nanosponges and the diverse methods for synthesizing, followed by the drug loading and release principle and application based on drug delivery, targeting, boosting solubility of BCS Class II and IV drugs, others in biomedicine and more. Finally, the recent progress on the use of biomimetic nanosponge as a pandemic tool due to the SARS-CoV-2 virus briefly comes into line.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
