Determination of ciprofloxacin using the Ziziphus mauritania derived fluorescent carbon dots based optical sensor

Abstract

The rapid determination and sensitive monitoring of antibiotics residues are critical challenges and highly essential for the protection of human and environment. Hence, in the present work, facile green synthesis of fluorescent carbon quantum dots (CDs) has been done using one step hydrothermal treatment of fruit exact of Ziziphus mauritiana for the first time, acting as natural source of carbon for optical determination of ciprofloxacin (CIP). These prepared CDs was used to selectively detect CIP, exhibiting high quantum yield of 30% at excitation wavelength of 340 nm. After the optimal parameters, the sensor gave the linear detection range from 20 to 100 µM along with limit of detection of 9.20 µM. The current work depicts the potential to effectively and rapidly determine other forthcoming environmental pollutants.
