- | ight has created innumerable wonders in nature. Equipped with tools and methods in optogenetic research, scientists have also achieved some truly fascinating goals in a synthetic way. This year, 2012 Peking-ECUST iGEM utilized an ultra-sensitive engineered sensor of luminescence -- the <b style="color:#ffee55;"> <i>Luminesensor</i></b>. Amazingly, the <i>Luminesensor</i> was proven to be so sensitive as to be able to detect <b style="color:#ffee55;">natural light</b> and even <b style="color:#ffee55;">bioluminescence</b>. With this sensor, spatiotemporal control of cellular behavior, such as <b style="color:#ffee55;">high-resolution 2D</b> and <b style="color:#ffee55;">3D bio-printing</b> using dim light and even the <b style="color:#ffee55;">luminescence of iPad</b> were shown to be very easy. What’s more, we successfully implemented <b style="color:#ffee55;">cell-cell signaling using light</b> for the very first time in synthetic biology, which will be of great importance for biotechnological use.

- | 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 <i>Luminesensor</i>, enabling highly efficient spatiotemporal control of biochemical process or cellular behavior. The whole job serves as a paradigm for sensor creating.

| |
- | The <i>Luminesensor</i> 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 <i>Luminesensor</i> 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 <i>E. coli</i> through light. By controlling the expression level of the CheZ protein with the <i>Luminesensor</i>, 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 <i>Luminesensor</i>, 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.
