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.

“…XRD is a powerful tool to study crystal materials to obtain information on structure, phases, and other structural parameters (Kohli, 2012; Rajeshkumar, Bharath, & Geetha, 2019). In studies on zein/polysaccharide nanoparticles, XRD has been used to investigate the state of the encapsulated compounds, such as resveratrol (Khan et al., 2019; Wei, Yu et al., 2019), quercetagetin (Sun et al., 2016), quercetin (Li et al., 2019), curcumin (Chen et al., 2020), PTX (Ngo, Tran, Lee, & Tran, 2019), and CoQ10 (Wei, Zhang et al., 2019), which were proved to be in the amorphous form after encapsulation into nanoparticles.…”

Zein, an alcohol-soluble protein in corn, can self-assemble into spherical nanoparticles, which makes it an ideal carrier material for the encapsulation of hydrophobic bioactive molecules. However, zein nanoparticles easily aggregate in water and are sensitive to enzymatic degradation in the digestive system. A strategy to overcome their limitations is the incorporation of polysaccharides as a second polymer layer that provides stability to zein nanoparticles. This review introduces the characteristics of zein as they relate to understanding the formation of zein/polysaccharide nanoparticles. Particular attention is paid to the preparation methods for the zein/polysaccharide nanoparticles, as well as to the morphological observation methods and detection mechanism. Moreover, the properties and applications of zein/polysaccharide nanoparticles are highlighted.

“…Another significant contribution to enhanced AgNPs antibacterial activity is their size, as smaller nanoparticles provide for larger contact area for interaction with the bacterial cells [41]. Inside the bacterial cell, AgNPs interact with cellular structures and proteins, lipids, enzymes, ribosomes and DNA, inevitably leading to bacterial dysfunction and finally apoptosis [43][44][45]. AgNPs could also cause increased production of high amounts of reactive oxygen and free radical species and reduce the ability of bacteria to produce antioxidant enzymes [45].…”

<p class="PaperAbstract">Polymer-based hydrogel materials are excellent candidates for new-generation wound dressings with improved properties, such as high sorption ability, good mechanical properties and low adhesiveness. Cross-linked hydrogel matrices also serve as excellent carriers for controlled release of antibacterial agents, such as silver nanoparticles (AgNPs), which are preferred over conventional antibiotics due to low propensity to induce bacterial resistance. In this work, we aim to produce novel silver/poly(vinyl alcohol)/chitosan (Ag/PVA/CHI) hydrogels for wound dressing applications. The electrochemical AgNPs synthesis provided facile and green method for the reduction of Ag<sup>+</sup> ions inside the hydrogel matrices, without the need to use toxic chemical reducing agents. The formation of AgNPs was confirmed using UV-visible spectroscopy, scanning and transmission electron microscopy. Release kinetics was investigated in modified phosphate buffer solution at 37 °C to mimic physiological conditions. Release profiles indicated “burst release” behavior, which is beneficial for wound dressing applications. The antibacterial activity was evaluated against Staphylococcus aureus and Escherichia coli strains using disc-diffusion test, and non-toxicity of hydrogels was proved by dye-exclusion test. The obtained results confirmed strong potential of Ag/PVA/CHI hydrogels for biomedical applications.</p>
