Processing techniques for deoxyribonucleic acid: Biopolymer for photonics applications

Abstract

Marine-based deoxyribonucleic acid (DNA), purified from waste products of the Japanese fishing industry, has recently become a material of interest in photonics applications. Using highly purified DNA, unique processing techniques developed specifically to transform the purified DNA into a biopolymer suitable for optical device fabrication are reported.

Chirality of sulforhodamine dye molecules incorporated in DNA thin films

“…To improve its film forming characteristics, the as-received high molecular weight ͑MW͒ DNA was sonicated 10 to reduce the average MW to approximately 200 kDa. Next, the DNA-Na is reacted with the cationic surfactant CTMA-Cl in water.…”

Enhanced emission efficiency in organic light-emitting diodes using deoxyribonucleic acid complex as an electron blocking layer

“…10,11 DNA-CTMA molecular weight reduction is performed by sonication to aid thin film formation and reduce electrical resistivity. 12 For devices reported here, the final DNA-CTMA molecular weight is ϳ145 000 Da, which is equivalent to 220 base pairs and an average molecular length of 75 nm. The electrical resistivity of separately fabricated DNA-CTMA thin films is ϳ10 7 ⍀ cm.…”

Biotronics

“…However, the process required to transform raw, genomic DNA from a natural, biological source into an optical quality material is non-trivial. This chapter will focus on the processing that has been developed in the past several years to form the optical-quality DNA biopolymer from genomic salmon DNA, the various dopants integrated into the DNA biopolymer, and the relevant optical, electronic and material characterization of the biopolymer for electronic and photonic devices (44,43,41,40,55,53,54,50,51,52,27,30,48,65,83,82,81) .…”
