“…From Table 6 it is very clear that, the ZnO NPs showed excellent activity against a higher intitial dye cocncentration of MB as (Fig. 9) [53]. The radicals originate from the oxidation of absorbed water or absorbed OH − and the presence of oxygen prevents the re-combination of electron-hole pairs which are generated by light of suitable energy absorbed by the ZnO nanoaparticles [39].The plenty of radicals produced by the absorbing more electron by surface oxygen enhances the discoloration and degradation of methylene blue by mineralization of the various intermediates…”

In this study, zinc oxide (ZnO) nanoparticle was synthesized by a novel route of microwave assisted method using ascorbic acid and PVA as capping agent and stabilizing agent. A prominent peak at 378 nm by UV absorption ensured the synthesis of ZnO nanoparticles. The crystalline property revealed that synthesized ZnO nanoparticle is highly crystalline having wurtzite structure. A significant band at ~ 498 to 557 cm −1 in FTIR was assigned to the characteristic stretching mode of Zn-O bond. EDX spectrum showed that ZnO nano particles were composed only with Zinc and oxygen. SEM image disclosed that ZnO nanoparticles were spherical in shape with an average particle size of 70-90 nm for the combined effect. The antimicrobial and ant-biofilm application of synthesized ZnO nanoparticle was studied against Salmonella typhi, Klebsiella spp. SK4, E. coli RN89, E. coli (gram-negative) and S. aureus-8a (gram-positive) bacteria and exhibited excellent activity against the strains. Prepared nanoparticle also found to possess outstanding photocatalytic activity against methylene blue degradation under sunlight with a T 50 and T 80 value of 71.44 and 165.87 min respectively.

Particles with size in the range of 1-100 nm, considered in any dimension, are called nanoparticles (NPs). Among various nanoparticles, nickel oxide nanoparticles (NNPs) are important because of their physical, chemical, and biological properties. In the past two decades, significant research has been done on the synthesis of NNPs. Their applications range from energy storage to catalysis to antifungal and antibacterial activity. This review provides a brief overview of various methods used for synthesizing NNPs, their properties, and their applications. The synthesis methods are classified into physical synthesis, chemical synthesis, and green synthesis involving plants and microorganisms, especially fungi. Particular focus is given to the types of precursors used for their synthesis, morphology, particle size, and applications.

Silver nanoparticles (Ag NPs) were prepared using Cassia auriculata leaves extract as a reducing agent via green synthesis method. From the PXRD, UV-Visible, FTIR, studies the synthesized NPs were characterized. The morphologies of the prepared NPs were studied by SEM and TEM analysis. The synthesized NPs were tested for antibacterial and anticancer studies. The PXRD data indicated that the synthesized nanoparticles belong to cubic phase structure. Presence of strong silver peaks was confirmed by EDAX studies. The SEM and TEM data revealed that spherical like structure were obtained. Antibacterial (MIC from 75 to 150 μl) activities were noticed for green synthesized Ag NPs. Furthermore, in vitro studies revealed dose-dependent cytotoxic effects of Ag NPs treated PC-3 cell line. This is the first report on the green synthesis of Ag NPs using leaves extract of C. auriculata. Results of present study could contribute to synthesize new and costeffective drugs from C. auriculata by using green approach.
