Using Au-Ag alloy nanoplates with various shapes, it is found that the porous structures of the nanoplates affect their photothermal conversion efficiency more than their laser energy absorption capacity does. Based on these findings, the optimized Au-Ag alloy nanoplates can be applied to LDI-TOF-MS of small molecules. (C) 2018 The Korean Society of Industrial and Engineering Chemistry.
