This tiny patch could replace biopsies—and revolutionize how we detect cancer

A new nanotechnology breakthrough may soon eliminate the need for painful biopsies. Scientists have developed a patch filled with nanoneedles thinner than a human hair that can painlessly extract molecular data from tissues without removing or damaging them. This enables real-time disease monitoring, particularly for conditions like brain cancer and Alzheimer s, and could radically change how doctors diagnose and track disease. The patch works quickly, integrates with common medical tools, and provides results using AI, opening doors to personalized medicine and better surgical decisions.
