Adsorption behaviour of pollutants: Heavy metals, radionuclides, organic pollutants, on clays and their minerals (raw, modified and treated): A review.

Graphene-based nanomaterial for desalination of water: A systematic review and meta-analysis.

The importance and need for eco-oriented technologies has increased worldwide, which leads to an enhanced development of methods for the synthesis of nanoparticles using biological agents. This review de-scribes the current approaches to the preparation of biogenic silver nanoparticles, using plant extracts and filtrates of fungi and microorganisms. The peculiarities of the synthesis of particles depending on the source of biocomponents are considered as well as physico-morphological, antibacterial and antifungal properties of the resulting nanoparticles which are compared with such properties of silver nanoparticles obtained by chemical synthesis. Special attention is paid to the process of self-assembly of biogenic silver nanoparticles.

Biogenic Silver Nanoparticles: Synthesis and Application as Antibacterial and Antifungal Agents

The development of novel nanoscale vehicles for drug delivery promotes the growth of interest in investigations of interaction between nanomaterials. In this paper, we report the in vitro studies of eukaryotic cell physiological response to incubation with graphene oxide and planar kaolin nanoclay. Graphene family materials, including graphene oxide (GO), hold promise for numerous applications due to their unique electronic properties. However, graphene oxide reveals toxicity to some cell lines through an unidentified mechanism. Thus, methods and agents reducing the toxicity of graphene oxide can widen its practical application. We used a colorimetric test, flow cytometry and cell index assay methods to evaluate the effects of separate and combined application of graphene oxide and kaolin on mammalian cells. We have shown that the joint application of graphene oxide and kaolin reduced the negative effects of graphene by almost 20%, most likely because of coagulation of the nanoparticles with each other, which was detected by atomic force microscopy.

Kaolin alleviates the toxicity of graphene oxide for mammalian cells

—The antibacterial nanocomposites creation is a current trend against microbial contamination and microorganism’s biofilm formation Existing methods for producing nanocomposites based on silver nanoparticles are difficult, expensive, and not environment friendly; therefore it has become necessary to develop a new method for their synthesis that didn’t have these minus The paper discusses the possibility of silver nanoparticles synthesizing and obtains a new nanocomposite using halloysite nanotubes and ultrasound Transmission electron microscopy revealed the silver nanoparticles presence on the inner and outer surface of halloysite nanotubes, and sample mapping showed a uniform distribution of silver nanoparticles in the nanocomposite The antibacterial activity of the obtained nanocomposite against the strain Serratia marcescens (S marcescens) was more than twice higher than that of the control The swarming motility method showed that the diameter of migration of S marcescens was 205 ± 005 cm, and in the presence of the nanocomposite, it was 163 ± 004 cm, indicating the ability of the nanocomposite to inhibit biofilm formation in these bacteria In the future, the obtained nanocomposite can be used as an additive to various materials or as a coating protecting against bacterial contamination of various surfaces and materials
