MALDI/TOF is mainly used for what purpose?

MALDI/TOF, which stands for Matrix-Assisted Laser Desorption/Ionization Time-of-Flight, is primarily used for the identification of molecular structures, particularly in the field of mass spectrometry. This technique allows for the analysis of biomolecules such as proteins, carbohydrates, and nucleic acids by converting them into ions and measuring their mass-to-charge ratios. The high sensitivity and speed of MALDI/TOF make it invaluable for identifying compounds present in complex mixtures, such as clinical samples, where rapid and accurate identification can assist in diagnosing infections or providing information on other conditions.

While measuring chemical reactions, conducting genetic analyses, and testing pharmaceutical effects are significant aspects of laboratory work, they do not primarily involve the specific capabilities of MALDI/TOF technology. This technique's focus on molecular identification sets it apart as a tool primarily for analyzing and characterizing various substances rather than for general chemical analysis or the study of genetic material. Thus, the choice reflecting its main purpose accurately highlights its role in identifying molecular structures.
