Cadmium sulfide is one of the most vital materials, and this research discusses the environmentally friendly synthesis of CdS nanoparticles using Bacillus subtilis. Bacterial synthesis was utilized to produce cadmium sulfide nanoparticles within Polyvinyl Alcohol (PVA) at four distinct concentrations. This study focused on generating CdS/ PVA films, where cadmium sulfide nanoparticles of varying sizes were dispersed within polyvinyl alcohol matrices. The PL (Photoluminescence) spectrum and UV–visible spectrum showed the CdS/PVA quantum confinement effect. TEM and XRD analyses demonstrate the formation of well-dispersed CdS nanoparticles and CdS films with a cubic phase embedded within the PVA matrix. The morphological changes between the nanocomposite clearly showed in the TEM images. Primarily spherical shaped CdS nanoparticles were formed as observed in the SEM analysis, and it was found that the CdS/PVA nanocomposite are different like shapeless. FTIR spectrums of CdS/PVA nanocomposites in different concentration shows the participation of biomolecules in the nanocomposite's formation. The prepared nanocomposite showed potential anti-inflammatory, antioxidant and antimicrobial activity against microbial pathogens. Thus CdS/PVA nanocomposites can be used in many potential biomedical applications. © 2024 Elsevier B.V.
