Sensing in biological systems
… In Chapter 2, we took a unique approach to Ca²⁺ sensing with a rationally designed sensor which possess all the desirable characteristics (brightness, photostability and red fluorescence emission) of both the traditional and spiropyran-type sensor. This was accomplished by combining a traditional …
