      abstract     = {Sensitivity enhancement is an important aspect of the
                      development of ultrasensitive biosensors. Single-trap
                      phenomena observed in liquid-gated nanostructures provide a
                      new opportunity to enhance the sensitivity of nanoscale
                      biosensors. The impact of light excitation on properties of
                      a unique nanowire (NW) field-effect transistor (FET)
                      structures utilizing single trap phenomena are studied. We
                      revealed that parameters of single trap and interface
                      phenomena in NW FET can be effectively tuned in a controlled
                      way using optical excitation. Under the influence of optical
                      radiation, the population of discrete levels is
                      redistributed, which allows to control of their energy
                      characteristics and, as a result, establishes the optimal
                      sensitive regimes. A model of the potential profile
                      description for carriers in NW structure is discussed to
                      describe the mechanisms of capture dynamics in fabricated NW
                      FETs and to control sensitivity in advanced biosensors.},
