Label-free imaging of membrane potential using membrane electromotility.
Electrical activity may cause observable changes in a cell's structure in the absence of exogenous reporter molecules. In this work, we report a low-coherence interferometric microscopy technique that can detect an optical signal correlated with the membrane potential changes in individual mammalian cells without exogenous labels. By measuring milliradian-scale phase shifts in the transmitted l...
متن کاملLabel-Free Vibrational Spectroscopic Imaging of Neuronal Membrane Potential.
Detecting membrane potentials is critical for understanding how neuronal networks process information. We report a vibrational spectroscopic signature of neuronal membrane potentials identified through hyperspectral stimulated Raman scattering (SRS) imaging of patched primary neurons. High-speed SRS imaging allowed direct visualization of puff-induced depolarization of multiple neurons in mouse...
متن کاملA membrane bending model of outer hair cell electromotility.
We propose a new mechanism for outer hair cell electromotility based on electrically induced localized changes in the curvature of the plasma membrane (flexoelectricity). Electromechanical coupling in the cell's lateral wall is modeled in terms of linear constitutive equations for a flexoelectric membrane and then extended to nonlinear coupling based on the Langevin function. The Langevin funct...
متن کاملLabel-free detection of clustering of membrane-bound proteins.
We report a new and label-free method to detect and characterize the clustering of membrane-bound proteins and, by extension, the lateral segregation of nanosized particles adsorbed to planar surfaces in liquid environment. The method exploits the contrast between two different mass and surface sensitive detection methods, quartz crystal microbalance with dissipation monitoring and ellipsometry...
متن کاملLabel-free optical imaging of membrane patches for atomic force microscopy
In atomic force microscopy (AFM), finding sparsely distributed regions of interest can be difficult and time-consuming. Typically, the tip is scanned until the desired object is located. This process can mechanically or chemically degrade the tip, as well as damage fragile biological samples. Protein assemblies can be detected using the back-scattered light from a focused laser beam. We previou...
