Biomarker Network

Biomarkers are substances used as indicators of a biologic state Biomarkers divided genetic and molecular biology methods into three different types. 1) Natural history markers 2) Drug activity markers 3) Surrogate markers. A biological molecule found in blood, other body fluids, or tissues that is a sign of a normal or abnormal process, or of a condition or disease. A biomarker is used to test how well the body responds to the treatment for different diseases in different conditions. Biomarker is also called as Molecular Marker and Signature Molecule.

A Biomarker can be any kind of molecule indicating the existence, past or present, of living organisms. In the fields of geology and astrobiology, biomarkers are also known as bio signatures. The term is also used to describe biological involvement in the generation of petroleum. Many new biomarkers are being developed that involve imaging technology. Imaging Biomarkers have many advantages. They are usually noninvasive, and they produce intuitive, multidimensional results.

In medicine, a Biomarker can be a substance that is introduced into an organism as a means to examine organ function or other aspects of health. For example, rubidium chloride is used as a radioactive isotope to evaluate perfusion of heart muscle. Biomarkers are gaining prominence in social science research, in particular in the field of consumer behaviors.
