(a) Schematic representation of the cytobot construct and circuitry showing the mechanism for electron-tunneling-modulation in pLGQD-network atop spore. Image is not to scale. (b) n-doping with poly-L-lysine and partially compensated p-doping by spore attachment in pLGQDs results in red-shift and blue-shift in Raman G-band spectra of parent EfGQDs, pLGQDs, and pLGQD-spore.
