Microwave Assisted in situ Coating of Silver Nanoparticles on Cotton Fabric using Kalanchoe delagoensis Leaf Extract and Screening of Biological Activity

The application of nanoparticle coatings on cotton through microwave heating is a well-established technique that has garnered considerable interest as an innovative and promising approach. Silver nanoparticles (AgNPs) get significant attention owing to their remarkable physical and chemical characteristics. The nanoparticles on cotton capping with phytochemicals has enhanced their applicability in the medicinal field. This study focuses on the green synthesis of silver nanoparticles on cotton using Kalanchoe delagoensis (AgNPs@KD) under microwave. UV-visible, XRD and EDX spectral reports shown the formation of AgNPs. SEM studies revealed spherical shape of nanoparticles with average particle size of 45 ± 5 nm and polydispersity index (PDI) below 0.5. AgNPs@KD and AgNPs coated cotton were meritoriously inhibited bacteria Klebsiella pneumonia, Escherichia coli, Staphylococcus, Bacillus and Fungi Candida, Aspergillus.
