Bit shifting operations by electric field-induced DNA strand displacement. a Right shifting of 010 (SSB) to 001 (LSB) . b Right shifting of 100 (MSB) to 010 (SSB) . c Fluorescence readouts of bit shifting operations. The fluorescence images show the readout data before (top panel, Cy5 channel) and after the parallel bit shifting (100–010) operation (middle panel, Cy5 channel, and bottom panel, FAM channel) on five three-bit cells
