What's Happening?
A new self-powered microneedle patch has been developed to monitor biomarkers without the need for blood samples. The patch collects dermal interstitial fluid (ISF) from beneath the skin's surface, which contains similar biomarkers to those found in blood. This innovation streamlines the biomarker testing process by providing cleaner samples and reducing the need for unpleasant blood draws. The patch consists of multiple layers, including microneedles that swell upon contact with ISF, facilitating fluid collection and storage.

Why It's Important?
This development represents a significant advancement in non-invasive medical diagnostics, potentially transforming how health monitoring and disease diagnosis are conducted. By eliminating the need for blood samples, the microneedle patch could improve patient comfort and accessibility to regular health checks. It also offers a more efficient and cleaner method for biomarker testing, which could enhance the accuracy and speed of medical diagnostics. The technology may benefit healthcare providers by reducing the complexity and cost of sample collection and processing.
