title: Data from: modifying cellulose fibers with carbon dots: a promising approach for development of antimicrobial fibers

description: This study focuses on the development of antimicrobial fibers for use in
 medical and healthcare textile industries. Carbon dots (CDs) were designed
 with boronic acid groups to attach to cellulose fibers found in cotton
 textiles and enhance their attachment to glycogens on bacterial surfaces.
 Boronic acid- (BACD) and curcumin-based CDs (PBA-CCMCD) were prepared and
 characterized using various techniques, showing a nanoscale size and zeta
 potential values. The CDs inhibited the growth of both Staphylococcus
 epidermidis and Escherichia coli bacteria, with UV-activated CDs
 demonstrating improved antibacterial activity. The antimicrobial activity
 of the CDs was then tested, revealing strong adherence to the cellulose
 paper fibers with no CD diffusion and potent inhibition of bacterial
 growth. Cytotoxicity assays on human cell lines showed no toxicity towards
 cells at concentrations up to 100 µg/mL, but exhibited increased toxicity
 at concentrations exceeding 1000 µg/mL. However, CD-modified cellulose
 paper fibers showed no toxicity against human cell lines, highlighting the
 antimicrobial properties of the CD-modified cellulose fibers as safe for
 human use. The findings show promising potential for applications in both
 industrial and clinical settings.
