Figure 2

Scanning electron micrographs of (b) a spore on silica and (a) a spore-pLGQD ensemble between electrodes is shown along with a TEM micrograph of pLGQDs. (c) Raman spectra of parent EfGQDs, spore, and the hybrid shows the presence of a luminescent background (from spore) and the characteristic D, G, and 2D bands of pLGQDs establishing the formation of the bio-hybrid.
