Biomarker detection is a research area focused on identifying specific biomolecules or biological markers that can indicate the presence of a certain disease, condition, or physiological state in an individual. These biomarkers can be found in various bodily fluids such as blood, saliva, urine, or tissue samples. Detection of biomarkers plays a crucial role in early diagnosis, monitoring disease progression, and assessing treatment efficacy. Various techniques such as immunoassays, mass spectrometry, and molecular biology methods are used to detect and measure biomarkers in biological samples. Biomarker detection is an important area of research in personalized medicine and plays a significant role in improving patient outcomes.
