¹Department of Chemical Engineering, University of Utah, ²The Nano Institute of Utah, University of Utah, ³Center for Photonics and Quantum Materials, Skolkovo Institute of Science and Technology, ⁴Biopharmaceutical Cluster 'Northern', Moscow Institute of Physics and Technology

A step-by-step procedure is described for label-free immobilization of exosomes and extracellular vesicles from liquid samples and their imaging by atomic force microscopy (AFM). The AFM images are used to estimate the size of the vesicles in the solution and characterize other biophysical properties.
