Here, we report a facile and rapid approach for the synthesis of multiband fluorescent graphitic carbon nanoparticles (CNPs) from queen of oils exhibiting multifarious applications. The as-prepared and calcined CNPs exhibited excitation dependent multiband emission that has been explored for detection of deoxyribonucleic acid (DNA) and removal of water pollutant cationic dye. We report here selective detection of Escherichia coli (E. coli-DNA) using fluorescent graphitic carbon nanoparticles through fluorescence enhancement of the nanoparticle. On the basis of thermal melting, CD and calorimetric studies, we could conclude that the interaction of CNPs are stronger with E. coli-DNA resulting in preferential selectivity for E. coli-DNA. The as-derived CNPs could be an emerging cost-effective material for the selective detection of E. coli-DNA and a sorbent for removal of basic pollutant dyes from water.
