Abstrakt: We have fabricated a twist nematic liquid crystal (TN) cell doped with guanine oligonucleotide (G10b) and measured its voltage-dependent transmittance (V–t) response. It is found that the operating voltage of a TN cell doped with G10b is higher than that of an undoped cell at 10 Hz. At a high frequency above 100 Hz, the V–t curve tends toward a saturated value equivalent to that of an undoped cell. The increase in the operating voltage depends on the concentration of G10b. This result suggests that G10b acts as an ion and produces an opposing electrical field between the electrodes. [ABSTRACT FROM AUTHOR]
