| Outline of Final Research Achievements |
Novel thermo-responsive magnetic conjugates composed of iron oxide particles, streptavidin and thermos-responsive polymer were developed to achieve high-efficiency enrichment and purification of circulating tumor cells (CTCs) with no stress. Controlling an amount of streptavidin on a surface of the conjugates, capture efficiency of CTCs increased from 25 to 60%. Observing the conjugates motion on lung cancer cells under microscope, the thermo-responsive conjugates captured and released cancer cells by changing temperature from body temperature (37°C) to lower temperatures. According to these results, the novel thermos-responsive conjugates has an advantageous for the high-efficiency enrichment and the purification.
