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.
Virus-Like Particles (VLP) mimics virions immunologically which induces high titers of neutralizing antibodies to conformational epitopes due to the high-density display of epitopes, present multiple proteins which are optimal for uptake by dendritic cells and are assembled in vivo. VLP triggers the immune response of the body against the diseases and is broadly two types like non enveloped VLP’s and Enveloped VLP’s. The present review discusses the production, analysis, and mechanism of action of virus-like particles. Various applications, the Indian Scenario of VLP, Limitations, and future scopes are briefly reviewed and discussed. VLPs imitate authentic viruses in antigenic morphology and offer a stable alternative to attenuated and inactivated viruses in the production of vaccines. It can effectively deliver foreign nucleic acids, proteins, or conjugated compounds to the system, or even to particular types of cells, due to their transducing properties. It retains the ability to infiltrate and render cells useful for a wide range of applications. Used as a tool to increase the immunogenicity of poorly immunogenic antigens, VLP therapeutics can be developed and manufactured in a way that would be sufficiently cheap to be seen globally in many countries. The ability to mass-produce them cost-effectively improves their possibility of being introduced to undeveloped countries.
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.
