| Abstract | This study reports the biogenic synthesis of silver nanoparticles (AgNPs) using aqueous extractobtained from Anacardium occidentale stem bark and evaluation of their antibacterial activities aswell as their potential applications as antimicrobial additives for detergent and toothpaste. Thebiosynthesized AgNPs were analyzed using UV–Vis spectroscopy, Fourier-transform infraredspectroscopy (FTIR), and scanning electron microscopy (SEM). The particles were dark brown incolour with maximum absorbance at wavelength 419 nm. They were mainly spherical in shapewith size ranges from 20 to 60 nm. The peaks of FTIR spectrum revealed that their formation wasfacilitated by protein molecules present in the extract. The AgNPs exhibited strong antibacterialproperty against pathogenic strains of Staphylococcus aureus, Escherichia coli and Pseudomonasaeruginosa. Furthermore, the incorporation of the AgNPs into a locally-made liquid detergent andtoothpaste led to complete inhibition of bacterial and fungal contaminants such as S. aureus, E.coli, P. aeruginosa, Aspergillus niger, and Aspergillus flavus. The results obtained herein thereforesuggest potential applications of the AgNPs in biomedical area and as antimicrobial additives inthe production of consumer care products like detergents and toothpastes. To the best of ourknowledge, this is the first reference to the use of biosynthesized AgNPs as antimicrobial additivesfor detergents and toothpastes. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
