      abstract     = {In this study, a scanning light-addressable potentiometric
                      sensor (LAPS) was applied for label-free and direct
                      electrical detection of DNA (deoxyribonucleic acid)
                      hybridization for the first time. The functioning principle
                      of the sensor is based on an electrostatic detection of the
                      intrinsic molecular charge of DNA molecules together with an
                      ion-concentration redistribution within intermolecular
                      spaces. The LAPS signal shows a distinct dependence on the
                      concentration of the complementary target DNA. The mechanism
                      of the shift of the photocurrent-voltage curve and the LAPS
                      signal generation induced by the DNA immobilization and
                      hybridization event is discussed.},
