• silver nanoparticles are shown as an exemplary application for quantitative analysis. Keywords: EGNP; enzymatically grown silver nanoparticles; enzyme-induced deposition; nanoflower; SERS; Introduction The application of metal nanoparticles in the field of bioanalytics extends the possibilities of

• nanoparticles [19][20][21]. The characterization of such enzymatically grown silver nanoparticles by atomic force microscopy [6] revealed an unusual, but very characteristic morphology: the desert-rose-like structure. This rose-like structure appears soon after the reaction is started and can be observed even

• contaminations. Therefore, the enzymatically grown silver nanoparticles were investigated by employing different microscopic techniques, namely scanning electron microscopy (SEM) and transmission electron microscopy (TEM), together with analytical methods, namely Rutherford backscattering spectrometry (RBS) and
