Abstract
Substrates for the surface-assisted laser desorption ionization (SALDI) technique were prepared using electrophoresis of gold nanoparticles produced by laser ablation in liquids. Throughout the preparation, no supplemental reagent was added for the stabilization and deposition of nanoparticles. Nanoparticles were deposited more uniformly using the electrophoresis technique than using dropping of the solution. Results demonstrated that the higher uniformity of the deposition of nanoparticles improved the reproducibility of SALDI measurements. Furthermore, the thickness of the deposited nanoparticles influences the SALDI efficiency.
