Previously, our group demonstrated using interference confocal reflectance microscopy (I-CRM) to measure collagen fibril diameters when suspended. An equally popular but optically unique challenge is presented when imaging collagen on glass, which is used for studying early stage fibril development. In this short manuscript, we present interference confocal reflectance microscopy as an alternative to atomic force microscopy for quantifying collagen fibrils below 50nm.
