Fabrication of Inverse Opal Hydrogel Sensor on Flexible Film Using Transfer Process |
| 초록 |
Photonic crystal is a periodic optical nanostructure which has photonic band gap. This structure can be made by using monodisperse polymer microsphere. Originally, we have used Polystyrene (PS) colloidal particles to make well-ordered opal structure by using the ‘Direct enhanced evaporation colloidal assembly (DEECA)’ process. I tried another process for transfer by applying the DEECA process. We could fabricate inverse opal structure composed of specific hydrogel by eliminating the polymer microsphere. This structure swells or shrinks as respond to a certain stimulus when it was exposed to solution with different condition due to ‘Gibbs-Donnan (equilibrium) effect’. The capability of this device can be enhanced by transferring to more flexible polymer substrates such as Polyethylene terephthalate(PET). This process is expected to be utilized for various applications like biosensor. |
