SUPPLEMENTARY NOTESApproved by 88ABW Public Affairs Office: Case number 88ABW-2013-0337 on 24 January 2013. Report contains color. ABSTRACTThis in-house effort processed deoxyribonucleic acid (DNA) and silk based bio polymer materials, aptamers and peptides into suitable electronic, photonic and chem/bio sensor materials. Blended nonlinear, metal, semiconductor, polymer, aptamer and peptide guests with biopolymers to enhance material properties taking advantage of self assembly/orientation and unique electromagnetic and optical properties. Fabricated and characterized test devices.

Optoelectronic studies on heterocyclic bases of deoxyribonucleic acid for DNA photonics

“…Two DNA strands organize a DNA double helix through hydrogen bonds between the bases and are stabilized by π-π interactions [39], which forms the foundation of DNA photonics [40,41]. Unsaturated molecules containing heterocyclic atoms can exhibit a characteristic absorption peak near 260 nm, which is due to π-π* transition of the electrons of C=C bond in DNA bases [42].…”

“…Unsaturated molecules containing heterocyclic atoms can exhibit a characteristic absorption peak near 260 nm, which is due to π-π* transition of the electrons of C=C bond in DNA bases [42]. The π orbital represents bonding orbitals while π* refers to anti-bonding orbitals.…”
