One step synthesis of functionalized carbon dots for the ultrasensitive detection of Escherichia coli and iron (III)

In this paper, we report a single step solid phase synthesis strategy for colistin modified fluorescent carbon dots ([email protected]) for the selective detection of gram-negative bacteria like Escherichia coli. Colistin is a well known cyclic polypeptide antibiotic drug but here we have used as a binding ligand for E. coli. Here also, the synthesised [email protected] are used for selective Fe3+ metal ion detection. The detection limits are...
