Blood Test Without Needles: A Revolution in Diagnostics Begins

Scientists from the University of North Carolina have made a breakthrough, presenting an innovative patch for medical tests. Now, collecting biomaterials becomes painless and does not require visits to the laboratory.

How does it work?

The surface of the device is covered with microscopic needles that imperceptibly penetrate the upper layers of the skin without affecting nerve endings. Within 15 minutes, the patch absorbs the necessary amount of interstitial fluid through swelling microchannels.

For most biomarker tests, blood samples are needed. The patch allows for a "cleaner" sample — it doesn't need to be processed

— explains Professor Michael Daniele, one of the creators of the technology.

Key advantages: • Complete painlessness — ideal for patients with phobias

• Long-term monitoring — works up to 24 hours without replacement

• High accuracy — interstitial fluid requires minimal processing

The device is already undergoing clinical trials, and in the future it will have built-in biosensors for instant diagnostics without laboratories.

The medicine of the future is becoming reality — convenient, technological, and accessible.
