AI Technical Summary
Existing microrobots have difficulty effectively scraping airway epithelial tissue or cells from the lungs, and lack the ability to control the sampling depth, resulting in easy sample detachment and making it difficult to meet clinical diagnostic needs.
A multi-level biomimetic spiky microrobot is designed, combining micron-level microspiky and nano-level gold spike structures. It utilizes magnetically driven rotational motion to achieve mechanical scraping and micro/nano entanglement. By integrating a magnetically driven inner cylinder with a multifunctional sampling outer shell, it achieves multi-level interactive sampling of airway tissues and stable sample anchoring.
It achieves effective scraping of airway tissue and cells, and the sample remains stably attached during the robot's movement. It can adjust the sampling depth according to the depth of the lesion to obtain samples with histological diagnostic value.
