A ratio-metric fluorescent off-on method for quantitative analysis of methylene blue in water and shrimp meat

Puntos clave

• Methylene blue detection achieved high sensitivity with a linear range covering 0.1 to 10 µM in water samples.
• Using a fluorescent off-on technique increased detection efficiency, facilitating real-time analysis of water quality.
• Assessment involved comparative analysis of shrimp meat samples, exploring health implications for consumers.
• This method supports environmental monitoring efforts, particularly in marine biology contexts, enabling better management of water quality.
