Turn-off/turn-on biosensing of tetracycline and ciprofloxacin antibiotics using fluorescent iron oxide quantum dots

Abstract

A fluorescence probe based on iron oxide quantum dots (IO-QDs) was synthesized using the hydrothermal method for the determination of tetracycline (TCy) and ciprofloxacin (CPx) in aqueous solution.

A novel N-CNDs/PAni modified molecular imprinted polymer for ultraselective and sensitive detection of ciprofloxacin in lentic ecosystems: a dual responsive optical sensor

“…These methods have shown excellent sensitivity, accuracy, and high-throughput screening capabilities. 4 However, the majority of them have inherent limitations that make them unsuitable for real-time field sample analysis, such as the need for expensive and complex instruments, issues with reproducibility, and time-consuming sample pretreatment. 5 The dual-sensing fluorometric/colorimetric technique is a vital choice over the other existing methods to detect POCs.…”

“…1,2 Tetracycline antibiotics (TCs), a type of broad-spectrum antibiotic, include oxytetracycline (OTC), demeclocycline (DMC), and tetracycline (TC), which are used in human therapy and as agricultural feed additives. 3,4 TCs are at the top of the list of antibiotics produced and used globally because they have few side effects and good bacteriostatic properties, and are inexpensive. 5 However, their residues in food of animal origin due to widespread use pose a serious threat to humans, 6–10 for example, severe damage to the central nervous system, damage to the liver and kidneys, allergy symptoms, etc.…”
