A water-stable formamidinium lead bromide perovskite nanocrystals@molecularly imprinted polymers fluorescent sensor for ultrasensitive detection of sulfadiazine

Key Points

• Ultrasensitive detection of sulfadiazine is achieved through a novel fluorescent sensor.
• The formamidinium lead bromide perovskite nanocrystals yield detection limits significantly below current standards.
• Analysis employs molecularly imprinted polymers to enhance selectivity for sulfadiazine compared to other compounds.
• Potential environmental monitoring applications are highlighted, emphasizing the need for this sensitive detection method.
