A Impact of buffer on the fluorescence intensity of Apt76-AgNCs and fluorescence quenching efficiency with TET. B Impact of the reaction time on the fluorescence quenching efficiency without TET. C Detection of TET using the developed biosensor. Fluorescence spectra with varied TET doses, as well as the biosensor’s response and analytical curves. D Selectivity of the sensor toward TET against other antibiotics (10 µg/mL). Three experiments resulted in error bars
