Ruby Muscovite Mica Surfaces for Electron Microscopy Sample Preparation

Agar Scientific offers freshly cleaved ruby muscovite mica surfaces that are flat, uniform, transparent and free from scratches and imputers. Ruby muscovite is a hard material and has superior cleaving properties. It simply separates into thin films along natural cleavage planes, and does not crack easily.

Cleaved mica is normally employed in electron microscopy for cell growing, thin film coating research, and for producing carbon support films. Additionally, ruby muscovite mica surfaces are ideal as substrates for high resolution atomic force microscopy analysis of DNA and DNA-protein complexes.

The process of mica cleaving involves insertion of a sharp point within a corner or edge of the mica sheet and gently separating the mica’s natural layers. For this purpose, a thin double edged razor blade can be used.

The freshly cleaved surface must be used quickly so as to use the clean and uniform surface. The initial thickness of the mica sheets differs between 0.10 and 0.25mm, and the minimum thickness depends on the skill of the person performing the cleaving process.

The range of mica sheets supplied by Agar Scientific is detailed in the table below.
