Abstract
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.
期刊介绍：
Environmental Nanotechnology, Monitoring and Management is a journal devoted to the publication of peer reviewed original research on environmental nanotechnologies, monitoring studies and management for water, soil , waste and human health samples. Critical review articles, short communications and scientific policy briefs are also welcome. The journal will include all environmental matrices except air. Nanomaterials were suggested as efficient cost-effective and environmental friendly alternative to existing treatment materials, from the standpoints of both resource conservation and environmental remediation. The journal aims to receive papers in the field of nanotechnology covering; Developments of new nanosorbents for: •Groundwater, drinking water and wastewater treatment •Remediation of contaminated sites •Assessment of novel nanotechnologies including sustainability and life cycle implications Monitoring and Management papers should cover the fields of: •Novel analytical methods applied to environmental and health samples •Fate and transport of pollutants in the environment •Case studies covering environmental monitoring and public health •Water and soil prevention and legislation •Industrial and hazardous waste- legislation, characterisation, management practices, minimization, treatment and disposal •Environmental management and remediation
