  • Patent number: 11348776
    Abstract: A disease diagnostic system where a sample preparation unit and/or a matrix-assisted laser desorption/ionization time-of-flight mass spectrometer (MALDI-TOF MS) data generation unit may be integrated in one system or a set of a system to improve the user-friendliness of the system. The system may include a sample preparation unit with processing modules and/or a handler to move samples in an autonomous manner to enhance reproducibility of measurement data and/or user-friendliness. A different set of processing modules may be selected for a particular disease type (e.g. such as cancer) to be diagnosed. The system may be used to identify biomaterials such as bacteria, virus, and fungi from body fluids like blood, urine, and saliva and other cells.

  • Patent number: 10481086
    Abstract: A mass spectrometer using near infrared (NIR) fluorescence can comprise: a plate formed such that a sample, which includes a matrix for ionization and a fluorescent material having an excitation wavelength of an NIR wavelength band, is loaded thereon; a fluorescence detection unit formed so as to acquire a fluorescence image by using the fluorescent material from the sample on the plate; a light emission unit formed so as to emit a laser beam for ionization at the sample on the plate; and an ion detection unit formed so as to detect, by using the laser beam, ions generated from the sample. By using the NIR fluorescence, fluorescence interference due to a matrix used for MALDI imaging can be excluded even after coating the matrix, and since fluorescence interference due to auto-fluorescence inside tissue is low, fluorescence can be measured even for a thick sample.
