Abstract
The growth of efficient infrared photoluminescent quantum dots directly on a DNA template was studied. The synthesis began with heating the DNA solution for 20 min under nitrogen at temperatures ranging in experiments from 20 to 100°C. Dark-field transmission electron microscopy (TEM) was carried out on a sample synthesized with highly polymerized, calf-thymus DNA and subsequently dried onto a carbon grid. The results show that the materials have high photoluminescence quantum efficiencies in aqueous solution and are stable in plasma at body temperature for over one week.
