Plant extracted natural fluorescent protein C-phycocyanin doped in PVA nanofibers for advanced apparel application

Abstract Natural dyes are gaining a great deal of attention due to their eco-friendly and sustainable properties for advanced apparel applications. However, the reproducibility accessibility various colors using natural remain challenging. In this study, plant-extracted fluorescent protein C-phycocyanin (CP) is used as dye source doped in polyvinyl alcohol (PVA) nanofibers via electrospinning The prepared show smooth bead-free surface morphology. FTIR results confirmed formation PVA followed by major peak at 3304 cm −1 stretching hydroxyl groups. Subsequently, CP-doping observed N–H deformation peaks 1541 ; C–N vibrations 1250 1092 C=O carboxyl group 1722 , respectively. Thus, CP-doped exhibit good color strength (K/S) 0.2 having blue tune fastness properties. mechanical increased from 6 MPa 18 MPa, crystalline characteristics endowed dope dyeing technique. Further, homogeneous bright red fluorescence individual nanofibers. Therefore, proposed can be flexible biosensor
