Substrate

Substrate

A substrate is a foundational or base material on which another material is applied or mounted.

The term is widely used in various fields like biology, chemistry, printing, and materials science. In the realm of printing, a substrate might refer to the paper or canvas that receives the ink. In biology, it could refer to the surface where an organism grows. Substrates are crucial in chemical reactions as well, often serving as the starting material in catalytic processes. Different substrates have different properties, such as absorbency and rigidity, which can dramatically affect the outcome of the process they are involved in.
