Determination of unbinding force and frequency of adhesion of functionalized AFM dendritips to their specific substrate coated on epoxy-activated glass slide coated. The frequency, the estimated unbinding force and force-curve distance are shown with AFM tip bearing in (A) monoclonal anti-β-1,3-glucan antibody versus laminarin, in (B) polyclonal anti-β-1,6-glucan antibody vs gentiobiose, in (C) WGA vs penta-N-acetylchitopentaose and in (D) conA vs mannan.
