Abstract
This invention enables a sensitivity enhancement in the detection of molecular compounds. A mass spectrometry analyte support with nanotube anchors are used to concentrate MALDI samples, specifically samples prepared with water-insoluble matrix compounds, on the anchor spot. The surface structure is established through patterned carbon nanotube anchor growth, providing a nucleation center for analyte and reducing sample precipitation on the surrounding MALDI wafer. Also disclosed is a method of creating a mass spectrometry support using patterned metal catalyst to grow carbon nanotubes. The carbon nanotubes enhance nucleation on specific areas of a sample plate to concentrate analyte/matrix deposit during droplet evaporation.
