Biogenic Green Synthesis of Nanoparticles from Living sources with Special Emphasis on Their Biomedical Applications

Abstract

Nanobiotechnology has been achieved great significance in terms of nanomedicine & many others. But the first challenge in nanobiotechnology science is the preparation of stable nanoparticles. Presently, many preparation methods have been developed like different chemical & physical processes, but the main drawbacks of these processes are required hazardous chemicals, environmental impact, and ultimately expenses a lot. To overcome these challenges another advanced technology has been developed, which is termed green or biogenic synthesis. This review is discussing the modern approaches of the eco-friendly and cost-effective methodology of green synthesis of nanoparticles by using different eukaryotic & prokaryotic agents like plants, human cell lines, diatoms, algae, fungi, bacteria, viruses, and other organisms. Also, this review gives a clear idea of the different applications of those nanoparticles in drug delivery, dentistry, labeling, diagnostics & sensors.

Water - Based Polyurethanes for Antibacterial Coatings: an Overview

“…By modifying the surface of silver nanoparticles, their cytotoxicity can be reduced by reducing the contact surface with cells. Also, in subsequent studies, researchers found that silver nanostructures can enter cells and affect DNA by releasing silver cations (Rather et al, 2021). In this regard, it has been determined that the antibacterial activity of silver nanostructures depends on the amount of silver cations released (Rather et al, 2021).…”

In general, by reducing the size of silver nanostructure, its antibacterial effect increases due to the increase in the concentration of released Ag + ions (Rather et al, 2021).…”

In general, by reducing the size of silver nanostructure, its antibacterial effect increases due to the increase in the concentration of released Ag + ions (Rather et al, 2021). Silver ions can stop the growth and reproduction of bacteria by binding to compounds containing phosphorus and sulfur in the membranes and DNA of bacteria (Tsou et al, 2016).…”
