A red-emitting carborhodamine for monitoring and measuring membrane potential

This paper introduces a new red-emitting fluorescent indicator, CRhOMe, capable of both monitoring and measuring membrane potentials with improved signal-to-noise and quantification using fluorescence lifetime imaging microscopy.

Topological action potentials in engineered tissues

The paper demonstrates that gap junction-coupled interfaces between non-excitable tissues can exhibit electrical excitability, a topologically protected phenomenon with broader ion channel expression tolerance than bulk excitability.

Feasibility analysis of semiconductor voltage nanosensors for neuronal membrane potential sensing

This study develops semiconductor voltage-sensitive nanorods for neuronal membrane potential sensing and demonstrates their feasibility for single-particle detection.

Bioelectrical signaling via domain wall migration

The paper demonstrates bioelectrical domain wall migration as a novel form of long-range signaling in tissues.

Multimodal on-axis platform for all-optical electrophysiology with near-infrared probes in human stem-cell-derived cardiomyocytes

The paper introduces an all-optical platform for high-throughput electrophysiology in human stem-cell-derived cardiomyocytes using optogenetic stimulation and optical imaging.
