Abstract |
Strongly motivated to open up a new era of optogenetics, our team has utilized an ultra-sensitive sensor which is engineered for sensing luminance – named by us Luminesensor, enabling highly efficient spatiotemporal control of biochemical process or cellular behavior. The whole job serves as a paradigm for sensor creating.
The Luminesensor is able to respond to very low light and meanwhile keep a wide dynamic range, which encouraged us to explore the possibility of cell-cell communication through light. We have successfully implemented, for the very first time, light-communication among cells without direct physical contact.
3D printing is a new technology that has been rising for many years. But in the realm of synthetic biology, it is far from developed. We exploited our Luminesensor to implement 3D printing that can be utilized in many medical or manufacturing applications.
"Phototatic" bacteria can be built by programming the chemotaxis system in E. coli through light. By controlling the expression level of the CheZ protein with the Luminesensor, the tumbling frequency is coupled to the intensity of light signals.
We have done a remarkable job in motivating high school students to study synthetic biology and guiding them towards future participation in the iGEM high school division. Besides, we collaborated with a lab and helped four other iGEM teams by sharing DNA materials, characterizing their parts and modeling. Furthermore, we presented all fresh iGEMers with a collection of praise for historic iGEM projects.
Excellent stochastic simulation was conducted to describe our ultrasensitive Luminesensor, combining protein kinetics and reaction thermodynamics. Molecular docking was also operated. What's more, while designing our photo-taxis model, we developed a hexagonal-coordinate environment for dynamic simulation of "on-plate" system. Those who focus on cell motility will find it useful and inspirational.
