Biomarker research involves the identification and study of specific biological markers that indicate the presence of a disease, condition, or physiological processes in the body. These biomarkers can be proteins, genes, metabolites, or other molecules that can be measured and analyzed to diagnose, predict, or monitor disease progression. This research area is important in advancing personalized medicine, early detection of diseases, monitoring treatment response, and developing new diagnostic tools and therapies. Biomarker research is multidisciplinary and involves fields such as biochemistry, genetics, molecular biology, and bioinformatics.
