Core Insights - The research team from the Shenzhen Institute of Advanced Technology, Shenzhen University, and the Chinese University of Hong Kong has developed a 1mm diameter blood gel fiber micro-robot that mimics the morphology and movement of nematodes for precise drug delivery in animal brains [1][2] - This micro-robot utilizes a combination of the animal's own blood and magnetic particles, allowing it to avoid immune rejection and degrade naturally after completing its task [1] Group 1 - The micro-robot is made of ultra-flexible hydrogel, softer than the intestine and tougher than cartilage, enabling it to navigate through narrow spaces without damaging surrounding tissues [2] - Researchers have validated the performance of this micro-robot in the brains of live pigs, indicating its potential for non-invasive drug delivery in extremely narrow physiological environments [2] Group 2 - Future research will focus on optimizing the structure and improving the motion control precision of the micro-robot to enhance its adaptability in complex brain environments [2] - Despite the promising results, there are significant safety and ethical challenges that must be addressed before human application can be considered [2]
