The advent of the electron microscope, the findings of J. David Robertson, the proposal of Singer and Nicolson, and additional work of Unwin and Henderson all contributed to the development of the modern membrane model. However, understanding of past membrane models elucidates present-day perception of membrane characteristics.
Fluid mosaic model of a cell membrane. The fluid mosaic model explains various characteristics regarding the structure of functional cell membranes.According to this biological model, there is a lipid bilayer (two molecules thick layer consisting primarily of amphipathic phospholipids) in which protein molecules are embedded.
The actin-based membrane skeleton (MSK) meshwork is directly situated on the cytoplasmic surface of the plasma membrane. Membrane skeleton fence, or membrane skeleton corralling model, suggests that this meshwork is likely to partition the plasma membrane into many small compartments with regard to the lateral diffusion of membrane molecules.
The structure of the membrane is now known in great detail, including 3D models of many of the hundreds of different proteins that are bound to the membrane. These major developments in cell physiology placed the membrane theory in a position of dominance and stimulated the imagination of most physiologists, who now apparently accept the theory ...

The earliest model bilayer system developed was the “painted” bilayer, also known as a “black lipid membrane.” The term “painted” refers to the process by which these bilayers are made. First, a small aperture is created in a thin layer of a hydrophobic material such as Teflon .
The models of the homodimers were verified through comparison with available experimental data for nearly 600 proteins. [4] The database includes downloadable coordinate files of transmembrane helices and their homodimers with calculated membrane boundaries. Membranome 3.0 version incorporates models generated by AlphaFold 2. [5]
Membrane Theory may refer to: M-theory, a theory in physics that unifies all of the consistent versions of superstring theory; Membrane theory of shells, describes the mechanical properties of shells; Membrane potential, a theory that explained the resting potential of nerve and muscle as a diffusion potential
