科研人员开发可用于癌症免疫治疗的“纳米标记机器人”

Core Insights - The research team led by Han Shuo at the Chinese Academy of Sciences has developed a "nano-marking robot" that can precisely identify cancer cells using a chemical biology technique known as proximity labeling [1] Group 1: Technology and Innovation - The proximity labeling technology is described as a powerful "molecular mapping" technique that catalytically marks the surrounding environment at specific locations within cells [1] - The "nano-marking robot" can carry antibodies or ligands that recognize cancer cells, enriching on the surface of these cells through blood circulation [1] - The robot can receive commands via deep red light or ultrasound to mark cancer cells clearly, effectively creating "artificial targets" [1] Group 2: Research Outcomes - The study has shown promising results in tumor models in experimental mice and in vitro clinical tumor samples [1] - This research is expected to pave the way for the development of smarter and more efficient next-generation immunotherapies [1]
