We demonstrate continuous-wave laser-based ambient mass spectrometry imaging with the use of a gold-nanoparticle layer substrate. When a fresh tissue slice is placed on a gold-nanoparticle layer substrate and irradiated with a 532-nm continuous-wave laser, the transmission-mode laser configuration provides precise desorption performance to facilitate mass spectrometry imaging. The subsequent ionization process with nonthermal atmospheric pressure plasma jets generates sufficient amounts of molecular ions. By using this method, micrometer-spatial-resolution mass spectrometry imaging of humid tissues can be obtained. The gold-nanoparticle layer substrates can be prepared and stored in advance of the experiment, resulting in simplified specimen preparation and an advantage in faster preparing of fresh tissue specimen for analysis.
