In addition to sensitivity, selectivity, and portability, chemical sensing systems must generate reliable signals offer modular configurability address various small molecule targets, particularly in environmental applications. We present a versatile, strategy utilizing ratiometric molecularly imprinted particle probes based on BODIPY indicators dyes for recognition internal referencing. Our approach employs polystyrene core particles doped with red fluorescent as an standard, providing built-in reference influences. A polymer (MIP) shell, incorporating green-fluorescent indicator monomer thiourea binding site carboxylate-containing analytes, is grafted from the presence of analyte template. The dual-fluorescent MIP probe detects fexofenadine model change green emission signal referenced against stable signal, achieving detection limit 0.13 μM broad dynamic range 0.16 1.2 mM, good discrimination other antibiotics acetonitrile. By selecting versatile dye scaffold element, this can be extended analytes and/or wavelength combinations, potentially serving robust multiplexing platform.
