A successful identification of DNA–DNA recognition, based on the waveguide effect of a 1D hybrid prismatic hexagon crystal interfacing of DNA with an organic semiconductor is achieved. This bio-hybrid 1D crystal simultaneously discerns the complementary case at its one end against a 1-mer mismatch in 27-mer nucleic acid sequence at the other end. The loss coefficient value of this waveguide is estimated to be 0.159 µm−1 for the perfect match, which is a stark discrepancy compared to 0.244 µm−1 for the 1-mer mismatch, implying waveguide performance with a higher efficiency. These results demonstrate successfully that multiple biological interactions can be realized by the optical waveguide of the single 1D bio-hybrid-crystal and will push this class of materials into bio-related applications.
