Fig. 6. (a) and (c) SEM view of samples. The black window shows the area analysed. (b) and (d): EDS spectra, dotted lines correspond to Au peaks (samples coated with
gold for SEM observations) and Os is the osmium labelling. (a, b) Analysis performed on a dense unorganized mesh of nanofibres (sample from coatings on a block). Note the
absence of an osmium peak on the spectrum in the grey box due to the purely mineral nature of nanofibres. (c, d) Analysis performed on a dense non-random mesh of nanofibres
(sample from a coating on a block associated with a decaying fungal strand). Note the presence of osmium peaks on the spectrum due to the organic nature of nanofibres.
