HIGH-RESOLUTION IMAGING MASS SPECTROMETRY USING POLYMER-COATED FINE PARTICLE

PROBLEM TO BE SOLVED: To provide a high-resolution imaging mass spectrometry capable of analyzing two-dimensionally an analyte contained in a sample such as a living cell and a tissue, with spatial resolution higher than a crystal grain diameter of an existing matrix. SOLUTION: A polymer-coated fine...

Summary:PROBLEM TO BE SOLVED: To provide a high-resolution imaging mass spectrometry capable of analyzing two-dimensionally an analyte contained in a sample such as a living cell and a tissue, with spatial resolution higher than a crystal grain diameter of an existing matrix. SOLUTION: A polymer-coated fine particle is deposited onto a core comprising a metal oxide, in a biological specimen containing the cell or the tissue. COPYRIGHT: (C)2009,JPO&INPIT
