N2 - Surface-assisted laser desorption/ionization (SALDI) mass spectrometry was performed using gold nanorods deposited on ITO plates. The degree of aggregation of the nanorods was controlled on the plates, and the relationship between the SALDI signals and the longitudinal surface plasmon (SP) bands of the gold nanorods were examined. Highly efficient SALDI processes were obtained when the bandwidth of the SP bands was about 300 nm. Optical dark field and SEM observations showed that fusion and ablation of nanorod-assemblies consisting of 4-10 gold nanorods contributed to the efficient SALDI processes.
