新型传感器实现循环肿瘤细胞高灵敏度检测

Core Insights - The research team at Jiangnan University has developed a biosensor that combines nano-fluorescent probes with microfluidic droplet technology for the high-sensitivity detection of circulating tumor cells (CTCs) in whole blood [1][2] - CTCs are critical in cancer metastasis and are present in very low quantities, making their detection challenging [1] - The new droplet sensor shows a significant improvement in detection sensitivity, achieving stable detection down to 5 CTCs/mL [2] Group 1 - The biosensor can specifically identify CTCs and has been validated in clinical samples from colorectal cancer, cervical cancer, and liver cancer [2] - The research aims to provide reliable technological means for early cancer warning, dynamic efficacy assessment, and precise postoperative treatment [2] - The potential for industrial application of this technology is being actively pursued [2]
