In this study, we propose innovative deoxyribonucleic acid (DNA)-based gels and their applications in diverse optoelectronics. We prepared the optoelectronic DNA-based gels (OpDNA Gel) through molecular complexation, that is, groove binding and ionic interactions of DNA and DHV. This process is feasible even with sequence-nonspecific DNA extracted from nature, resulting in the expansion of the application scope of DNA-based gels. OpDNA Gel possessed good mechanical characteristics that have not been observed in typical DNA hydrogels. We successfully demonstrated its applicability in a variety of functional electrochemical systems, including on-demand information coding systems, user-customized EC displays, and microorganism monitoring systems. The OpDNA Gel is a promising platform for the application of DNA-based biomaterials in electrochemical optoelectronics. |
