New unique optical and electric properties of intermediate filaments in Müller cells

Presently we report new unique optical and electric properties of Müller cell (MC) intermediate filaments (IFs). We inform that these IFs extracted from porcine retina are excellent conductors of light and electric current. Such IF properties may endow vertebrate eyes with high-contrast vision. The properties of the IFs allow a simple quantum-mechanical description that justifies the quantum mechanism (QM) for the light energy transfer between the inner and the outer limiting membranes. These properties also provide direct and unequivocal proof that QM works even in isolated IFs, while the classic theory admits no capacity for light transmission by objects that are so thin. Note that the length and diameter of the IFs were 117 ± 1.3 μm and 10.1 ± 0.07 nm, respectively. The QM avoids the light scattering effects, which could significantly reduce the visual contrast, by conducting light energy in the form of excitons (excited states). This scientific breakthrough may provide new insights for medical ophthalmology.
