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