“…Then, these metal ions undergo enzyme-catalyzed bioreduction, leading to the formation of nanoclusters that disperse into the solution. 62 In this process, the emergence of specific colors is indicative of the formation of distinct types of NPs. b) Extracellular synthesis method, wherein precursor materials are adsorbed outside the cell surface and subsequently undergo enzymatic transformation into NPs.…”

Synthesis of nano‐particles using various greener approaches such as the use of plant extract, microbes, etc. is gaining a lot of popularity in the scientific community due to their advantages of being a cheaper protocol, reduction in the use of less hazardous chemicals, more environmentally benign method and good yield. It has been previously reported by many research groups that plant material provides reducing, capping as well as stabilizing agents and brings down biological and environmental risks in the green synthesis of nano‐particles. So it was thought worthwhile to synthesize copper oxide nano‐particles (CuO NPs) using some locally available medicinal plants. Rivina humilis L. plants which are available in our region of Vidarbha in Maharashtra State, India are considered to be the herbal plant for the treatment of respiratory‐related disorders mainly for asthma and cold by local tribal peoples. It has been found that it contains a variety of phytochemicals which can be employed for the synthesis of nanomaterials. With this aim it was thought worthwhile to present an efficient and greener approach for the synthesis of copper oxide nano‐particles using Rivina humilis L. (RH) whole plant extract. For characterization of bio‐synthesized CuO NPs, various spectral and analytical techniques such as UV‐Vis spectroscopy, FT‐IR, XRD, SEM, TEM, and EDS were employed. The newly synthesized CuO NPs were also tested for their potential biological activities against six different bacterial stains namely E. coli, P. aeruginosa, S. aureus, P. vulgaris, B. subtilis, and S. typhi using the well diffusion method. The antioxidant efficacy of the synthesized CuO NPs was undertaken through 1,1‐Diphenyl‐2‐picrylhydrazyl (DPPH) free radical scavenging activity. Their results have been presented and discussed in the present work.

This study compares chemical and green synthesized zinc sulfide nanoparticles for multiple biological properties. A chemical synthesis approach is utilized to synthesize PEGylated ZnS‐NPs while the bulbs of Fritillariae cirrhosae bulbus are utilized for green synthesis. After extensive characterization, the NPs are examined for multifunctional biological properties such as antimicrobial, antioxidant, in vitro anticancer, and blood compatibility. Our study found that chemical synthesis results in higher yield and better dispersion behavior. However, the green ZnS‐NPs possessed increased antibacterial and antiparasitic potential against Leishmania tropica as the NPs resulted in significant inhibition against Staphylococcus aureus (S. aureus) and Bacillus subtilis (B. subtilis) with minimum inhibitory concentration (MIC) of 0.156 and 0.312 mg/mL, respectively while IC50 of 115.21 and 128.5 µg/mL were observed for the promastigote and amastigote forms of parasite. Furthermore, Fritillaria cirrhosa (F. cirrhosa) synthesized NPs possessed slightly improved antioxidant properties and in vitro anticancer potential against MCF‐7 breast cancer cells. Despite differences in the biological properties, the NPs did not result in hemolytic behavior thus demonstrating the compatible nature against blood cells. It was thus evident from the present study that the chemical and green synthesis techniques not only result in NPs with different physicochemical characteristics but also significantly influence the bio‐interaction of the obtained ZnS‐NPs.
