Extended Data Fig. 4: Electron microscopy images of the microbe–semiconductor hybrids and controls.
From: Maximizing light-driven CO2 and N2 fixation efficiency in quantum dot–bacteria hybrids
a, HRTEM image of the microbe–semiconductor hybrid. b, The magnified image of the red box in a. c, The magnified image of the red box in b. d, The corresponding Fourier transform results of c indicating a lattice spacing of 0.22 nm for the QDs. e, TEM image of the microbe–semiconductor hybrid. f, The magnified image of the red box in e. g, HAADF-STEM image of sectioned microbe–semiconductor hybrid in the absence of cysteine. h, HAADF-STEM image of sectioned pure microbes. The experiment of electron microscopy has been repeated independently for more than 3 times with similar results. Scale bars are 1 μm in a, 20 nm in b, 500 nm in e, 50 nm in f, and 200 nm in g and h.
