                 In hope of ?? the value of our biological heating device, we strive to improving the sensitivity of our sensor - the cold shock promoter. This final goal can be break down on two parts: 1. tuning the temperature-responsive range of cold shock promoter 2. amplifying its signal under low temperature. In order to understand what kind of structure of a genetic circuit and what kinds of characteristics of activator and repressor are needed for our purpose, we create several mathematical models to explore the problem. In the end, we expect to get some useful information as a guidance to screen possible biological parts when we actually start to construct the genetic circuit.
