Cell-Surface-to-Solution Signal Transduction via a CRISPR/Cas12a-Based Dual-Target Aptamer Sensor for Detecting Urothelial Carcinoma Cells in Urine
Urothelial carcinoma (UC) is a common malignancy of the genitourinary system with high recurrence rates, requiring non-invasive postoperative monitoring. Direct detection of exfoliated UC cells in urine can provide tumor-origin evidence but remains challenging because of low target-cell abundance, complex urine inter...
