Biomarker detection

Definition

Biomarker detection refers to the identification and measurement of biological markers, which are measurable indicators of a biological condition or process, often used in disease diagnosis, prognosis, and treatment monitoring. This concept is crucial in understanding how optical properties of tissues can reveal information about cellular changes and disease states, leading to better diagnostic tools. Furthermore, it plays a pivotal role in the development of precision medicine and theranostics, where specific biomarkers guide tailored therapies for individual patients.
