| Abstract(in English) | In recent years, biosensors not requiring labelling have been receiving much attention. We have been developing a biosensor based on optical properties of gold particles. To prepare particles, we first form a dense monolayer of uniform polystyrene spheres, diameter ranging from 55nm to 152nm, on a substrate. Evaporating 5nm to 40nm of gold on the above spheres results in gold particles exhibiting pronounced absorption in the visible range, with optical density of well over 2. We have shown that when octadecanethiol molecule forms a self-assembled monolayer or biothin/avidin binding takes place on the gold surface, the absorption peak wavelength shifts over 10nm. |
