“…Bacillus amyloliquifaciens strain KSU-109 produced surfactin, which helped in the synthesis of stable cadmium sulfide nanoparticles of average size of 3-4 nm (Singh et al, 2011). Escherichia coli E-30 and Klebsiella pneumoniae K-6 have been shown to synthesize cadmium sulfide nanoparticles with average size ranging from 3.2 to 44.9 nm and showed highest antimicrobial activity on A. fumigatus, G. candidum, B. subtilis, S. aureus, and E. coli strains (Abd Elsalam et al, 2018). Serratia marcescens mediated synthesized antimony sulfide nanoparticles were reported with size range <35 nm (Bahrami et al, 2012), while Pseudomonas aeruginosa ATCC 27853 mediated synthesis of selenium nanoparticles were reported with a size of 96 nm (Kora and Rastogi, 2016).…”

In the recent times, nanomaterials have emerged in the field of biology, medicine, electronics, and agriculture due to their immense applications. Owing to their nanoscale sizes, they present large surface/volume ratio, characteristic structures, and similar dimensions to biomolecules resulting in unique properties for biomedical applications. The chemical and physical methods to synthesize nanoparticles have their own limitations which can be overcome using biological methods for the synthesis. Moreover, through the biogenic synthesis route, the usage of microorganisms has offered a reliable, sustainable, safe, and environmental friendly technique for nanosynthesis. Bacterial, algal, fungal, and yeast cells are known to transport metals from their environment and convert them to elemental nanoparticle forms which are either accumulated or secreted. Additionally, robust nanocarriers have also been developed using viruses. In order to prevent aggregation and promote stabilization of the nanoparticles, capping agents are often secreted during biosynthesis. Microbial nanoparticles find biomedical applications in rapid diagnostics, imaging, biopharmaceuticals, drug delivery systems, antimicrobials, biomaterials for tissue regeneration as well as biosensors. The major challenges in therapeutic applications of microbial nanoparticles include biocompatibility, bioavailability, stability, degradation in the gastro-intestinal tract, and immune response. Thus, the current review article is focused on the microbe-mediated synthesis of various nanoparticles, the different microbial strains explored for such synthesis along with their current and future biomedical applications.

Nanotechnology is a developing branch of pharmaceutical sciences wherein the particles extend in nanosizes and turn out to be more responsive when contrasted with their unique counter parts. In the past numerous years, the utilization of synthetic concoctions and physical strategies were in mould; however, the acknowledgment of their toxic impacts on human well-being and condition influenced serious world view for the researchers. Presently, green synthesis is the watch word for the combination of nanoparticles (NPs) by plants or their metabolites. This innovation is particularly compensating as far as decreasing the poisonous quality caused by the conventionally integrated NPs. In this review, we cover the perspectives by which metal particles can be integrated from green methods in the perspective of green methods utilized in the NPs combination. In the green strategies, plant metabolites and natural substances are utilized to orchestrate the NPs for the pharmaceutical and other applications. Some characterization methods are also reviewed along with applications of NPs.

“…microemulsions, condensation and hydrothermal techniques, the use of ultrasonic radiation [13][14][15][16][17] as well as biological processes [18]are used in the preparation of CdSNPs.However, the use of these methods was limited because of low yields, excessive cost, tedious syntheticprocedures, andthe use of various toxic chemicals. In those methods, various chemicals such as dimethylformamide, thioglycerol, thiourea, sodium dodecyl sulphate, diethylenetriamine, cetyltrimethylammonium bromide, 3-mercaptopropionic acid and thiophenol have been used as capping agents which might cause health and environmental issues [13][14][15][16][17][18][19].…”

“…25 mg of CdSNPs was dissolved in 1 mLof dimethyl sulphonyloxide and screening, as well as evaluation of the antimicrobial activity, was performed [18]. For the antibacterial test, four bacterial species;S. aureus, E. coli, S. typhi and P. aeruginosawere cultured in Mueller Hinton Broth and 4 h after the culture, standard McFarland was matched.…”

Cadmium sulfidenanoparticles (CdSNPs) were prepared through the chemical precipitation process where sweet potato starch and glucose-functioned as capping agents. Ultraviolet-Visible (UV-Vis) spectroscopy, Fourier Transform Infrared (FTIR) spectroscopy and X-ray diffraction (XRD) techniques were applied for the analysis of prepared CdSNPs. The absorption peaks in the UV-Vis spectroscopy towards the lower wavelength region compared to the bulk CdS (512 nm) indicated the formation of CdS particles in the nanometer scale range. FTIR spectroscopy showed the characteristic absorption peaks of the CdSNPs along with the functional groups present in starch and glucose, suggesting the possible interaction between CdSNPs and capping agents. The XRD revealed crystallographic information such as the average crystallite size and shape of CdSNPs. Using the Scherrer equation, the average crystallite size of CdSNPs was determined to be 11.48 nm and 16.03 nm for starch-capped and glucose-capped CdSNPs (CdS-St andCdS-Gl)respectively. Antibacterial and antifungal activities of the prepared CdSNPs were found to be highly efficient for various pathogenic bacteria and fungi. Hence in the present study, the new synthetic route of CdSNPs was applied, and antimicrobial activities were performed
