The demand for higher computing performance exists since the first computing systems were built. According to Moore’s law the number of components on an integrated circuit roughly doubles in every two years. Silicon based computing systems are heading towards their limitations, therefore the need for alternative solutions increased. The use of proteins in computing systems seems to be a promising option to give an alternative. Previous researches were made on Coulomb coupled protein systems, where the key was the dipole moment of the molecules.

In the past few years continuous engineering on proteins enabled the utilization of a new range of molecules with several features. Reversibly switchable fluorescent proteins are promising candidates to be a base of computing systems. This thesis aims to present the operation of fluorescent proteins and their applications in data storage and computing systems. An equivalent circuit model of a reversibly switchable fluorescent protein is implemented to demonstrate the dipole moment change of a molecule in case of irradiation on different wavelengths. Simulation was set up in MATLAB Simulink and the results were discussed.
