(a,b) TEM images of L. casei cells in (a) Au(−) and (b) Au(+). (c,d) SEM micrographs of L. casei cells in (c) Au(−) and (d) Au(+). The white square in (d) indicates the area for EDS analysis in (e). (e) EDS from the squared area in (d). The arrows showed the characteristic X-ray spectra of Au. (f) XRD pattern from the dried L. casei cells in Au(+).
