Add Tag | Summary: | Diatoms are an abundant living being along the planet, from which their outer structures are quasi symmetrical and thus represent an ideal template for further functionalization and plasmonic decoration. This study performs an extensive analysis where light wavelength is tested as reductor agent during the in-situ synthesis process of both Gold and Silver nanoparticles. Different exposure times and an additional reductor agent are used to compare the efficiency and effects of nanoparticles sizes and shapes. Finally, comparative analysis were developed before and after DNA attachment, with fluorescence and raman spectroscopy techniques, to decorated frustules in order to test viability as biosensors. From here, Silver decoration seems to work the best for sensing under raman signals, while Gold decoration under fluorescence microscopy. |
