This work is focused on molecular dynamics simulations of artificial photosensitive ion channel and AFM probe. To assemble this ion channel, DFT methods were employed for reparametrization of the GAFF force field describing the bridged azobenzene, which was used as a light controlled molecular switch. We proved by molecular dynamics simulations that newly developed parameters correctly describe behavior of assembled model of ion channel in a lipid bilayer. We also constructed a model of AFM probe and observed formation of water meniscus between the AFM probe and surface, both made of α-quartz, by employing molecular dynamics simulations. A contribution of this work is the set of new parameters extending GAFF force field for description of the bridged azobenzene. We also verified functionality of ion channel model and model of AFM probe, which can be used for the further water meniscus studies.
