Mass spectrometry (MS) has profoundly transformed modern biomedical analysis, offering unparalleled sensitivity, specificity, and speed across a wide spectrum of applications, including disease diagnostics, drug discovery, proteomics, and metabolomics [1].
Key advancements in ionization techniques, such as electrospray ionization (ESI) and matrix-assisted laser desorption/ionization (MALDI), alongside sophisticated mass analyzers like time-of-flight (TOF) and Orbitrap, have empowered researchers to identify and quantify a vast array of biomolecules, ranging from proteins and peptides to metabolites and lipids, even at trace levels [1].
This remarkable capability is indispensable for unraveling the complexities of biological systems, identifying crucial biomarkers for early disease detection, and facilitating the development of highly targeted therapeutic strategies [1].
Proteomics, the large-scale study of proteins, heavily relies on mass spectrometry for protein identification, quantification, and the detailed characterization of post-translational modifications (PTMs) [2].
Advanced MS techniques, particularly tandem MS (MS/MS), are essential for sequencing peptides and identifying proteins within intricate biological samples, providing vital insights into cellular functions, signaling pathways, and disease mechanisms [2].
Metabolomics, which involves the comprehensive study of small molecules or metabolites within biological systems, has experienced significant propulsion due to the widespread adoption of mass spectrometry [3].
LC-MS and GC-MS platforms are routinely utilized to profile and quantify hundreds to thousands of metabolites, offering a dynamic snapshot of cellular function and physiological state, which in turn aids in identifying metabolic biomarkers for various diseases [3].
In the realm of drug discovery and development, mass spectrometry plays a pivotal role in identifying potential drug candidates, characterizing their pharmacokinetic and pharmacodynamic properties, and monitoring drug metabolism with high sensitivity and specificity [4].
The application of mass spectrometry in clinical diagnostics is rapidly expanding, with MS-based assays offering substantial advantages over traditional methods, including increased throughput, enhanced sensitivity, and multiplexing capabilities for applications like newborn screening and cancer biomarker discovery [5].
The integration of ion mobility spectrometry-mass spectrometry (IMS-MS) introduces an additional dimension of separation based on ion size, shape, and charge, providing enhanced resolution and enabling the separation of isobaric species, proving valuable for biomarker discovery and analysis in complex biological mixtures [6].
