black membrane (medicine)


black membrane
<chemistry> An artificial phospholipid membrane formed by painting a solution of phospholipid in organic solvent over a hole in a hydrophobic support immersed in water. Drainage of the solvent from the film produces diffraction colours until the thickness falls below the wavelength of light it then appears to be black.
