摘要 |
Research at the interface between nanotechnology and life science has the potential to produce breakthroughs in fundamental science and lead to revolutionary technologies. Herein, I will show how we use chemically enabled design and processes to fabricate functional nanoelectronic devices based protein and to map the cellular behaviors in a nanomechanical way. On one hand, the natural biomaterials like proteins can be used for the fabrication of solid-state memory devices for the first time, where a controllable and reproducible bipolar memristive nanodevice based on ferritin can be fabricated by chemical immobilization of ferritin molecules within on-wire lithography-generated nanogaps. Such ferritin-based nanodevices with reversible resistance can be used for nonvolatile memory based on write-read-erase cycle tests. Furthermore, sericin, one of silk proteins, can be used to fabricate nonvolatile memory device for the first time. On the other hand, we can use cellular nanomechanical forces to fundamentally study the cellular behaviors associated with dynamic physicochemical interactions, where the dynamic forces and molecular components that shape these interactions. An example on nanomechanically probing the interaction between nanoparticles and epithelial cells will be given. We found that nanoparticles induction of massive disruption to the intracellular microtubule assembly, thus triggering a positive feedback that promotes stronger adhesions with the substrates, limiting cell motility. |
