Researchers at The Jackson Laboratory (JAX), in collaboration with the Massachusetts Institute of Technology (MIT), have developed the first bandage-like microneedle patch that can sample the body's immune responses painlessly from the skin. The device detects inflammatory signals within minutes and collects specialized immune cells within hours without the need for blood draws or surgical biopsies.
