Microrobots Revolutionize Cell Navigation and Stimulation

Researchers at the Technical University of Munich have developed microrobots capable of navigating within groups of cells and stimulating individual cells. These round microbots, driven by laser light, are half as thick as a human hair and contain gold nanorods and fluorescent dye. The robots can heat up and indicate their temperature, allowing them to heat specific cells or cell groups. The technology has potential applications in studying cellular processes, wound healing, cancer treatment, and drug delivery. The microbots are produced using a microfluidic chip-based manufacturing process and can be mass-produced.
