This work reports the detection of natural amino acids with Ag nanoparticles as a matrix. We successfully detected all amino acids (as [analyte+Ag]+ ion), including in the mixtures of few amino acids. Moreover, a formation of other adducts, particularly [analyte+Ag3]+ and [analyte2+Ag]+ is reported. The differences in ion intensity ratios depending on amino acid types are discussed. The obtained results showed that laser ablation is more efficient for amino acids with hydrophobic, unique, and neutral side chains.
