A bilayer typically refers to a structure composed of two layers of materials or molecules. In biological contexts, such as cell membranes, a phospholipid bilayer is formed when hydrophobic tails face inward, shielded from water, while hydrophilic heads face outward. This arrangement creates a semi-permeable barrier, essential for cellular function and integrity. In materials science, bilayers can involve two distinct materials stacked to leverage their combined properties for applications like coatings or electronic devices.
