| Outline of Final Research Achievements |
The temperature, humidity, oxygen density and pH are controlled comfortably for creatures in the living environment. However, we need expensive systems to keep this due to the complexity by which more than one factors should be measured for more than one points in real time. In this study, the reporter aimed to develop the nanosheet-type fluorescence sensors, adhesive on the target surface, and a device for practical measurements. The temperature and oxygen sensors were successfully prepared by introducing fluorescence molecules sensing temperature and oxygen into polymer nanosheets and combining with a standard fluorescence nanosheet insensitive to those factors. The reporter designed a pH sensor by considering time resolution influenced by membrane thickness. Then, the reporter successfully prepared a nanosheet-type fluorescence pH sensor by synthesizing fluorescence-conjugated polymers, using a layer-by-layer method, and combining with the standard fluorescence nanosheet.
