High-throughput technologies have revolutionized biomarker discovery, significantly advancing molecular diagnostics by enabling the identification of novel markers at an unprecedented scale. These advancements are driven by sophisticated computational analysis and the integration of multi-omics data, shifting the paradigm from single-target approaches to comprehensive molecular profiling for enhanced disease detection and personalized medicine [1].
The application of single-cell multi-omics provides a powerful lens to dissect cellular heterogeneity in disease states, offering deeper insights into disease mechanisms and the promise of more precise diagnostic markers. By simultaneously analyzing genomics, transcriptomics, and epigenomics from individual cells, researchers can pinpoint rare cell populations or specific molecular signatures linked to disease onset and progression [2].
Liquid biopsies represent a significant leap forward in non-invasive biomarker discovery for various cancers, focusing on circulating tumor DNA (ctDNA), circulating tumor cells (CTCs), and extracellular vesicles (EVs).
