The strategy of chemical coprecipitation is implemented to synthesize nanoparticles of pristine CuSe, 5 and 10% Nidoped CuSe, and 5 and 10% Zn-doped CuSe. All of the nanoparticles are found to be near stoichiometric by the evaluation of X-ray energy using electron dispersion spectra, and the elemental mapping shows uniform distribution. By X-ray diffraction examination, all of the nanoparticles are identified as being single-phase and having a hexagonal lattice structure. Field emission microscopy with electrons in both scanning and transmission modes affirmed the spherical configuration of the nanoparticles. The crystalline nature of the nanoparticles is confirmed by the presence of spot patterns observed in the selected area electron diffraction patterns. The observed d value matches well with the d value of the CuSe hexagonal (102) plane. Findings from dynamic light scattering reveal the size distribution of nanoparticles. The nanoparticle's stability is investigated by ζ potential measurements. Pristine and Ni-doped CuSe nanoparticles exhibit ζ potential values in the preliminary stability band of ±10 to ±30 mV, while Zn-doped nanoparticles feature moderate stability levels of ±30 to ±40 mV. The potent antimicrobial effects of synthesized nanoparticles are studied against Staphylococcus aureus, Pseudomonas aeruginosa, Proteus vulgaris, Enterobacter aerogenes, and Escherichia coli bacteria. The 2,2-diphenyl-1-picrylhydrazyl scavenging test is used to investigate the nanoparticle's antioxidant activities. The results showed the highest activity for control (Vitamin C) with an IC 50 value of 43.6 μg/mL, while the lowest for Nidoped CuSe nanoparticles with an IC 50 value of 106.2 μg/mL. Brine shrimps are utilized for in vivo cytotoxicity evaluation of the synthesized nanoparticles, which demonstrates that 10% Ni-and 10% Zn-doped CuSe nanoparticles are more damaging on brine shrimp instead on other nanoparticles with a 100% mortality rate. The lung cancer cell line of human (A549) is used to investigate in vitro cytotoxicity. The results indicate that pristine CuSe nanoparticles are more effective in the context of cytotoxicity against the A549 cell lines, possessing an IC 50 of 488 μg/mL. The particulars of the outcomes are explained in depth.

“…The peak at 544 nm is because of the transition between impurity bands in ZnSe NSs as the samples are zinc-deficient. The donor bands of selenium and acceptor bands of zinc give impurity transitions (observed in the EDAX spectra) Figure b,c shows the 3D surface plot of the PL spectra and the enlarged portion of Figure a in the wavelength range of 450 to 500 nm.…”

Microorganisms create various health issues; semiconductor nanostructures have raised interest because of antimicrobial properties for suppressing microbial growth. Herein, we report the synthesis of ZnSe nanostructures (NSs) using a green coprecipitation method, and the assynthesized samples were annealed at 100, 150, and 200 °C temperatures. The synthesized samples were analyzed for structural, morphological, optical, and antibacterial properties. The growth of nanorods was confirmed by TEM micrographs and that of nanoparticles by FESEM and TEM micrographs. The cubic zinc blender phase of samples was confirmed by XRD. The high-intensity electron−phonon (e−ph) interactions and LO modes were confirmed by the Raman spectra. The UV−visible absorption spectra predicted the blue shift in optical band gaps of ZnSe NSs from their bulk counterparts. The PL spectra and associated CIE diagram indicated that the as-synthesized and annealed NSs produce blue color. The investigated antimicrobial activity against Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus implies the superior biological activity of the as-synthesized and annealed samples at 200 °C. The annealing enhances photoluminescence and antimicrobial activities of ZnSe NSs. The enhanced luminscence properties of ZnSe NSs make them suitable for preparing more efficient blue LEDs and lasers for medical applications. The as-synthesized and annealed ZnSe NSs are found effective against the growth of microorganisms, and sustaining this tendency for 1 week provides a strong basis for the development of new drugs against bacterial infections for supporting the pharmaceutical industry.
