High throughput near infrared screening discovers DNA-templated silver clusters with peak fluorescence beyond 950 nm

We use high throughput near-infrared (NIR) screening technology to discover abundant new DNA-stabilized silver clusters, AgN-DNA, that fluoresce in the NIR. These include the longest wavelength AgN-DNA fluorophores identified to date, with peak emission beyond 950 nm that extends into the NIR II tissue transparency window, and the highest silver content.
