Substrate research is a field of study that focuses on the various materials or surfaces on which biological organisms, chemical reactions, or physical processes occur. This includes examining the properties, characteristics, and interactions of different substrates with organisms or molecules. Substrate research is important in various areas of science, such as biology, chemistry, and materials science, and can help in developing new materials, understanding biological processes, and improving industrial processes. Researchers in this field study the physical, chemical, and biological properties of substrates to better understand how they influence the behavior of organisms or reactions taking place on them.
