Outline of Final Research Achievements

In this study, the printed nanofilm was constructed through integration of printing technology and molecular assembly into the preparation of free-standing polymer nanosheets. Introduction of conductive polymers or nanoinks to the building blocks of nanosheets realized skin-contact electrodes and electronics. Then, phase separation led to preparation of porous nanosheets, allowing for permeation of several substances from molecules to cells, on which stem cells were cultured in the application of cell delivery. Furthermore, nanosheet-based thermosensor embedded with thermo-sensitive dyes realized real-time imaging of thermogenesis on the muscle tissue from cells to tissues.
