Photo-thermal Effect of PEDOTs for the Detachment of Living Cell Sheets |
| 초록 |
The photo-thermal (PT) effect of conducting polymer is one of the important phenomena for the cell harvesting technology. The absorption of poly(3,4-ethylenedioxythiophene) (PEDOT) films in the near-infrared (NIR) region was effectively triggered cell harvesting upon exposure to an NIR laser. The heating of PEDOT surface by PT effect induced unfolding of absorbed collagen triple helices, yielding soluble collagen single-helical structures. Such local dissociation of collagen layer provided a non-invasive method for cell sheet harvesting at the NIR irradiated area. The correlation of cell sheet detachment and PT heating of PEDOT was established. |
