“Nanotechnology” is an emerging as a significant development tool for the green synthesis of noble nanomaterial. Green synthesis is superior to conventional chemical methods as it is less expensive, reduced pollution, and enhances human health and the environment safety. Nanomaterial and their green synthesis from plants became an interesting aspect of nanotechnologies due to the many benefits they provide to living beings, as well as their low cost and minimal harm to humans and the environment. They also have a wide range of applications in biomedical research, diagnostics, and drug discovery and also in catalysis. The current review focuses on the synthesis of nanoparticle from plants using greener approach and their novel applications.
For field-like environmental
gas monitoring and noninvasive illness
diagnostics, effective sensing materials with exceptional sensing
capabilities of sensitive, quick detection of volatile organic compounds
(VOCs) are required. Carbon-based nanomaterials (CNMs), like CNTs,
graphene, carbon dots (Cdots), and others, have recently drawn a lot
of interest for their future application as an elevated-performance
sensor for the detection of VOCs. CNMs have a greater potential for
developing selective sensors that target VOCs due to their tunable
chemical and surface properties. Additionally, the mechanical versatility
of CNMs enables the development of novel gas sensors and places them
ahead of other sensing materials for wearable applications. An overview
of the latest advancements in the study of CNM-based sensors is given
in this comprehensive organized review.
The lightweight, low-density, and low-cost natural polymers like cellulose, chitosan, and silk have good chemical and biodegradable properties due to their individually unique structural and functional elements. However, the mechanical properties of these polymers differ from each other. In this scenario, chitosan lacks good mechanical properties than cellulose and silk. The synthesis of nano natural polymer and reinforcement with suitable chemical compounds as the development of nanocomposite gives them promising multidisciplinary applications. Many kinds of research are already published with innovative bio-derived polymeric functional materials (Bd-PFM) applications. Most research interest is carried out on health concerns. Lots of attention has been paid to biomedical applications of Bd-PFM as biosensors. This review aims to provide a glimpse of the nanostructures Bd-PFM biosensors.
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.
