Nanosilver-doped carbon quantum dots for industrialization of efficacious textiles with superior UV-resistance and antimicrobial performance

Abstract

Numerous researches were interestingly considered with investigation of unique strategies for industrialization of efficacious textiles to find wide-scaled applicability in different purposes. The demonstrated approach represents unique strategy for manufacturing of fluorescent/UV-resistant/microbicide cotton via exploitation of silver nanoparticles (AgNPs), carbon quantum dots (CQDs) and silver nanoparticles-doped carbon quantum dots (AgNPs-CQDs) to be applicable as efficacious textiles. Whereas, both CQDs and AgNPs were formerly clustered from alginate biopolymer. Topographical features and particle size of AgNPs (7.5 ± 2.6 nm), CQDs (4.9 ± 1.7 nm) & AgNPs-CQDs (4.0 ± 1.4 nm) were investigated via microscopic images and Zetasizer data. Spectral mapping data for the photoluminescent emission showed that, AgNPs, CQDs & AgNPs-CQDs were exhibited with two intense peaks at 370 nm & 490 nm. Cotton fabrics were sequentially treated with CQDs, Ag-CQDs & AgNPs-CQDs to prepare CQDs@Cotton, Ag-CQDs@Cotton and AgNPs-CQDs@Cotton, respectively. Thermal stability, colorimetric properties/color strength, UV-resistance and antimicrobial potentiality were studied for all the prepared samples. AgNPs-CQDs@Cotton exhibited excellent UV-resistance (UPF, 43.4) and antimicrobial activity, whereas the diameter of inhibition zone was estimated for its affinity against S. aureus, E. coli and C. albicans, to be 14 mm, 18 mm and 16 mm, respectively.
