  • Biomolecular synthesis of quantum dot composites
    Patent number: 5985353
    Abstract: A biomimetic approach utilizing biomolecular self-assembly is described to form nanometer particle size composites for uses, such as, nonlinear optical media. Yeast tRNA was utilized as an ion-exchange/nucleation site within a polymeric matrix (polyacrylamide). Cadmium ion-exchange and subsequent sulfide precipitation resulted in formation of nanometer particle size composites. Illumination of samples with an Argon laster (514 nm) utilizing the Z-scan measurement method resulted in third order nonlinearity .chi..sup.3 values of +2.7.times.10.sup.-6 esu.
