Dual-responsive Zr(iv) MOF based fluorometric sensor for rapid and selective detection of anti-cancer drug dacarbazine and herbicide oryzalin in environmental and biological samples

for DCZ, indicating strong analyte interactions. The probe showed a rapid response time of 10 s for both analytes and exhibited excellent selectivity against potential interferents. Thus, this study presents the first fluorometric-based dual probe specifically designed for DCZ and ORZ detection. The sensor's high sensitivity, rapid response, and strong selectivity make it a promising tool for monitoring hazardous analytes in environmental and biological settings. The insights gained from experimental and computational analyses further support the practical utility of this Zr-based MOF sensor in real-world applications.
