| Research Abstract |
Our study reports a new method of in situ EB lithography in a non-vacuum liquid environment for a complete living cell; in the future, this research could lead to nano-surgery by molecular mechanics on a cell membrane. We expect this first demonstration of in situ nano processing and cellular nano stimulation can be utilized for real time analysis of changes in membrane protein dynamics. Our nano processing on a culturing living cell using an EB-induced reaction could directly manipulate the molecular physical dynamic function and chemical property of the environment. Moreover, theoretically, the EB had less than a nanometer scale wavelength, and the electron range in water was also 10s nm. Therefore this method can provide new approaches for in situ molecular level dynamics manipulation on membrane dynamics-related disorders, for example cancer metastasis, and repairing and regenerating neurons after injury; by combining it with single molecule imaging it can be used to understand how spatio-temporal dynamics affects their mechanisms.
