Bringing Attomolar Detection to the Point‐of‐Care with Nanopatterned DNA Origami Nanoantennas

open access: yesAdvanced Materials, EarlyView.
Single DNA molecules are captured within the hotspots of DNA origami NanoAntennas arranged on a chip surface. Fluorescence is amplified, enabling direct detection on a point‐of‐care‐compatible imaging setup (visualized as bright signals against a dark background).
