Collagen fibrils act like nanoscale cables in the extracellular matrix of vertebrate tissues and provide a scaffold for cells to attach to. However, beyond this mechanical function, the surface charge of collagen fibrils is also likely to play an imp

Muscovite mica is a widely accepted substrate for scanning probe microscopy (SPM) investigations. However, mica has intrinsic properties that alter samples and obstruct their analysis due to free charges build-up, ionic exchange and water adsorption
