Base-modified aptamer-DAPI probe for label-free detection of doxorubicin in dairy and serum samples

Doxorubicin is an important chemotherapeutic agent, making its sensitive detection essential for therapeutic monitoring and food safety assessment. Although DNA aptamers exhibit high affinity and specificity toward doxorubicin, the absence of well-defined structural motifs often...

Aptamer-Based Fluorescent Biosensors for Kanamycin Detection in Food Systems: Design Strategies, Sensing Mechanisms, and Practical Applications

Kanamycin (KANA), a widely used aminoglycoside antibiotic in animal husbandry, is associated with residue accumulation in foods due to improper use, threatening food safety. Detecting trace KANA in complex food systems such as dairy, meat, and apicutural products remains challeng...
