Torsional Noise of a Colloidal Probe in Contact with Surface-Grafted PEG Layers

Surface coatings modify the interaction between microparticles and surfaces. To analyze the effect of a PLL-g-PEG surface coating on the sticktion of a microparticle, we analyzed the torsional Brownian fluctuations of a colloidal probe attached to an atomic force microscope (AFM) cantilever. Results...
