TEM micrographs recorded on a drop-coated film with yeast biomass/AuNPs aqueous suspension, after 24 h (a and b). EDX spectra (c) and particle size distribution histogram determined from the TEM micrographs (d). XRD pattern recorded from the thin film prepared by drop coating the biomass/AuNPs aqueous suspension after 24 h on a Si wafer; the principal Bragg reflections are identified (e).
