"Revolutionary Nanoscale 'Cell Tattoos' Offer Early Health Problem Alerts"

Engineers have developed nanoscale tattoos that adhere to live cells, allowing for the placement of optical elements or electronics on individual cells. The tattoos, made of gold nanodots and wires, can flex and conform to the cells' structure. This breakthrough technology could enable the remote monitoring and control of cell health in real time, potentially leading to early disease diagnosis and treatment. The tattoos were successfully attached to cells for 16 hours without causing harm, and the researchers plan to explore more complex nanocircuits and different cell types in future experiments.
