Advanced Chromatographic and Spectroscopic Method Development for Biomarker Identification and Validation in Clinical Biochemistry

Abstract

The application of advanced chromatographic and spectroscopic methods has revolutionized the process
of biomarker identification and validation in clinical biochemistry, thus enhancing analytical sensitivity,
specificity and reproducibility. Several analytical techniques like liquid chromatography–mass spectrometry
(LC-MS/MS), gas chromatography–mass spectrometry (GC-MS), high-performance liquid chromatography
(HPLC), Raman spectroscopy, Fourier-transform infrared spectroscopy (FTIR), and nuclear magnetic
resonance (NMR), offer strong bases for the identification of complex biological molecules involved in
various diseases. The present study discusses recent advances in method development, optimization
and validation in the field of biomarker discovery in clinical diagnostics and personalized medicine. The
combination of multi-omics, automation and advanced mass spectrometry technologies has improved
clinical biomarker reliability and applicability for translation. In addition, analytical validation parameters
such as sensitivity, specificity, precision and accuracy are still key for clinical acceptance and regulatory
compliance. The study highlights the growing importance of advanced analytical technologies in improving
early disease detection, therapeutic monitoring, and precision healthcare.
