Seen here are microneedle-based skin patches for transdermal drug delivery and longitudinal sampling of cells and interstitial fluid, enabling minimally invasive parallel monitoring of immune responses. We took the image to assess the attachment of the bioactive coating on the microneedles surface. By having a well-attached coating, we will be able to deliver bioactive reagents in a more efficient way.
