Paper Abstract

We present the growth of efficient infrared light-emitting quantum dots directly on DNA. The nanoparticles emit in the second biological window 1050-1200 nm with photoluminescence quantum efficiencies of 11% in aqueous solution. The infrared fluorophores are stable for over a week in blood plasma at 37°C.
