摘要

PROBLEM TO BE SOLVED: To detect a signal of a molecule to be measured with sufficiently high sensitivity without using a matrix compound at the time of mass spectrometry by laser desorption / ionization mass spectrometry, and to measure a compound having a relatively high molecular weight. Also provides a substrate for laser desorption / ionization mass spectrometry that enables sufficient mass spectrometry. A substrate 1 has a pillar array structure composed of titanium nitride nanopillars 11 on one surface, and the average aspect ratio of the nanopillars forming the pillar array structure is 1.5 or more. And. [Selection diagram] Fig. 1
