Abstract

original image

Enter the dragon: An electrospun nanofiber mat is used to identify latent fingerprints on various surfaces within 30 seconds and produce inkjet-printed patterns. In contrast to classical approaches, the method is easy-to-operate, environmentally friendly, and has implications in other applied systems including chemical sensors, drug delivery, biological detection, and microreactors.
