A Fiber-Optic Voltage Sensor Based on Macrobending Structure [PDF]
We propose and demonstrate an optical voltage sensing scheme based on a macrobending optical fiber in a ratiometric power measurement system. This novel approach to sensing has not been utilized before and has the advantage that the sensor involves ...

NMDA Receptors as Voltage Sensors
2017The membrane potential is an essential parameter of a living cell. However, measurements of the membrane potential using conventional techniques are associated with a number of artifacts. Cell-attached recordings of the currents through NMDA receptor channels enable noninvasive measurements of the neuronal membrane potential.

The voltage-sensor structure in a voltage-gated channel
Trends in Biochemical Sciences, 2005A recent electron paramagnetic resonance study of KvAP, a prokaryotic voltage-gated channel, in its lipid native environment has revealed the location of the transmembrane segments, the connecting loops and the relative position of the voltage-sensing charges.

The voltage sensor for the depolarization-activated, Shaker K + channel (Kv) is well characterized as the transmembrane segment S4. In Kv channels, depolarization stimulates the outward movement (more residues of S4 exposed to the extracellular surface), and the channel opens. Männikkö et al.
