FAQ

Frequently Asked Questions

No, it is a specialised technical term used primarily in scientific disciplines.

No, 'bilayer' is exclusively a noun (and derived adjective). The process is described as 'forming a bilayer' or 'self-assembling into a bilayer'.

The lipid bilayer that constitutes the core structure of all biological cell membranes.

In technical contexts, they are often synonymous. However, 'bilayer' strongly implies the two layers are intimately associated and form a unified structure (like a membrane), while 'double layer' can be more general.

A structure consisting of two molecular layers.

Bilayer is usually technical/scientific in register.
