  • Desorption/ionization of analytes from porous light-absorbing semiconductor
    Patent number: 6288390
    Abstract: A method for desorption and ionization of an analyte from a porous, light absorbing, semiconductor is disclosed that can be used to replace conventional mass-assisted laser desorption/ionization (MALDI) in the mass spectrometry of proteins and biomolecules. The process uses the semiconductor to trap an analyte on the semiconductor. The semiconductor is illuminated by a light source and absorbs the light energy. The semiconductor then uses the light energy is to desorbed and ionize the analyte. The analyte so desorbed and ionized is suitable for detection by mass analyzers.

  • Method for sleep induction
    Patent number: 5612380
    Abstract: Sleep may be induced by administration of fatty acid primary amides, including cis-9,10-octadecenoamide. Furthermore, sleep deprivation may be assayed by analyzing cerebrospinal fluid with respect to the presence of fatty acid primary amides, including cis-9,10-octadecenoamide. The presence of cis-9,10-octadecenoamide in cerebrospinal fluid is correlated with comparative sleep deprivation.
