    摘要: The present invention relates to a method for high-sensitivity and high-specificity detection of biomolecules by using mass spectrometry and, more specifically, to a method for high-sensitivity and high-specificity detection of proteins such as miRNA or antigens by using time-of-flight secondary ion mass spectrometry (ToF-SIMS), matrix-assisted laser desorption/ionization (MALDI), or laser desorption/ionization (LDI) mass spectrometry. The method for high-sensitivity and high-specificity detection of biomolecules by using mass spectrometry, according to the present invention, enables high-sensitivity and high-specificity detection of biomolecules by using surface mass spectrometry, and the method is expected to be used for the diagnosis and prediction of diseases by quantifying, from a biosample, a target probe such as miRNA which is known as a disease marker.
