Abstract: DNA‐stabilized silver nanoclusters (DNA‐AgNCs) are a class of emitters that have primarily been studied for their molecular‐like photophysical properties with ns‐lived fluorescence. However, µs‐lived luminescence has recently been reported for an increasing number of DNA‐AgNCs,… read more here.

DOI: 10.1021/acsnano.4c09640
Abstract: DNA-stabilized silver nanoclusters (AgN-DNAs) have sequence-tuned compositions and fluorescence colors. High-throughput experiments together with supervised machine learning models have recently enabled design of DNA templates that select for AgN-DNA properties, including near-infrared (NIR) emission that… read more here.
