Abstract: We have detected second-order nonlinear optical response from an amphoteric mega-saccharides named sacran undera needle/ring electrode stimulus by using an optical second harmonic generation (SHG) microscope. SHG was observedfrom sacran in the neighborhood of the negatively biased needle electrode below -4.5 V with respect to the outer ringelectrode. From the incident light polarization dependence of SHG, this sacran was suggested to be oriented toward theelectrode needle. SHG of the sacran polymer was judged to be induced by sacran aggregates with net positive charge.
