Interaction between TA_pink1 and colloidal gold in liquid media. a Cyclic voltammograms of TA_pink1 after 0 and 17 h of incubation in the presence and absence of colloidal gold. Control, TA_pink1 incubated without colloidal gold. b Scanning electron micrographs of colloidal gold (CG) with the fungal hyphae (FH) of TA_pink1in liquid PYG medium after 14 days of incubation at 10 °C. Scale bar, 5 µm. c Detailed view of nanometer gold particles and surrounding materials (yellow arrows) over the surface of fungal hyphae. Scale bar, 5 µm. The inset shows an EDS profile of the major components of the assemblage
