Green fluorescent proteins as optically-controllable elements in bioelectronics


A single-biomolecule optical toggle-switch is demonstrated based on a mutated green fluorescent protein (GFP). We have exploited molecular biology techniques to tailor GFP molecular structure and photophysical properties and give it optically-controlled bistability between two distinct states. We present optical control of the fluorescence dynamics with two… (More)
