| Outline of Final Research Achievements |
In this study, to fabricate a biosensing substrate with ultra high sensitivity, active control of gold nanostructures on hydrogels was studied.
1. The method, by which gold nanostructures prepared on the silicon substrates was transferred onto the hydrogel, was improved. As a result, gold nanostructures were efficiently transferred onto the hydrogel and the transfer onto the thermoresponsive hydrogel was also succeeded.
2. Active gap control of gold nanostructures on the hydrogel was evaluated by the electron microscopy. It was observed that the gap distances were homogenously changed in a nanometer-scale. This result supports precise control of the gaps is possible using volume change of the hydrogels.
