Atomic Force Microscopy as a Tool for Biomedical and Biotechnological Studies

Abstract: This work presents different applications in progress with the aid of the atomic force microscopy (AFM) technique for biomedical and biotechnological applications, comprising both the acquisition of three-dimensional images and spectroscopic force measurements, in the following systems: first, low-density lipoprotein (LDL)-glycosaminoglycans; second, lectins-polysaccharides; third, mycobacterium leprae cellular wall and Vesicular Stomatites Virus (VSV) with fibronectin laminin, and lipidic membranes; fourth, D… Show more

“…Sections were blocked using a Sections were cut at 2 mm thickness and then immobilised on a glass slide. Sections were then incubated in a primary antibody solution (11) that was specific to the marker of interest, and a secondary (21) biotinylated antibody specific to the primary was added. A complex was then added consisting of an aggregation of avidin and biotin.…”
