A molecular imprinted SERS sensor based on a silver substrate for the selective capture and sensitive detection of crystal violet in textile wastewater

Key Points

• The aim is to develop a sensitive sensor using Ag-based molecularly imprinted polymers for detecting crystal violet in wastewater.
• Development of Ag@MIPs as a SERS substrate for crystal violet detection.
• Evaluation of the sensor's effectiveness in detecting unauthorized additives in textile wastewater.
• The sensor successfully detected crystal violet at low concentrations.
• Significant sensitivity and selectivity were achieved using the developed SERS substrate.
