• 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

• obtained from Virginia Semiconductor (n-type; undoped, <100>, >1000 Ω·cm). Quartz substrates were obtained from Quarzschmelze Ilmenau. Analytical Methods Unless otherwise indicated, NMR spectra were obtained on a Bruker DPX 300 spectrometer (1H NMR at 300 MHz; 13C NMR at 75 MHz). Some were performed on a
