A novel bioinspired carbon quantum dots based optical sensor for ciprofloxacin detection

Green route has been a centre of attraction for synthesizing carbon quantum dots from natural sources owing to its outstanding optical properties. In the current work, a novel bioinspired and fluorescent carbon quantum dots were prepared from Cinnamomum tamala (tejpata) leaves extract utilizing a simple one-step hydrothermal method for the first time. The current method delivers a high quantum yield of 31% having 340 nm excitation wavelength for detection of ciprofloxacin. The developed fluorescent sensor showed ciprofloxacin detection in the linear range of 1 to 100 μM, with a detection limit of 6.06 μM.
