Painless Patch for Immune Cells: Microneedle Device Promises Non‑Invasive Immune Monitoring

A collaboration between The Jackson Laboratory and MIT has produced a microneedle patch that non‑invasively samples immune cells from humans, enabling painless, repeatable collection for laboratory analysis. Published in Nature Biomedical Engineering, the device could reshape immune monitoring in clinical trials, vaccine development and personalised medicine, though validation, regulatory approval and ethical safeguards are still required.
