A protein fingerprint of a patient's blood sample can be created by adding the sample to a metal plate and striking it with a laser.This causes the sample to become ionized and the ions from the sample are guided into a machine that separates them and identifies them according to their mass-to-charge ratio. This process describes ________.

A protein fingerprint of a patient's blood sample can be created by adding the sample to a metal plate and striking it with a laser.This causes the sample to become ionized and the ions from the sample are guided into a machine that separates them and identifies them according to their mass-to-charge ratio.  This process describes ________.

This process describes MALDI-TOF (Matrix-Assisted Laser Desorption/Ionization Time-of-Flight), which is a technique commonly used for protein profiling and identification. "Lab on a chip" is a technology that integrates multiple laboratory functions on a single chip, PFGE (Pulsed-Field Gel Electrophoresis) is a technique used to separate large DNA molecules by size, PCR (Polymerase Chain Reaction) is a technique used to amplify DNA, and FISH (Fluorescence in situ hybridization) is a technique used to detect and locate specific DNA sequences in cells or tissue sections. None of these techniques match the description of creating a protein fingerprint with a laser.
