Chemical agent registration method on the basis of surface optical sensitization and surface plasmon resonance

New chemical sensing method on the basis of surface optical sensitization was proposed. High grade sensitivity of approach presented is determined by applying of surface plasmon resonance excitation in attenuated total reflection geometry. It was demonstrated of method working with arsenazo III in gas phase. Atomic-force microscopy images of silver halide crystals under surface optical sensitization by arsenazo III were obtained.
