4-(2-(6-(Dibutylamino)-2-naphthalenyl)ethenyl)-1-(3-sulfopropyl)pyridinium hydroxide inner salt has been used as a voltage sensitive dye in cardiac cells.[1]
Biochem/physiol Actions
Membrane potential dye that responds to changes in membrane potential monitored by fluorescence excitation changes at 440 and 505 nm; correlated to changes in membrane potential of the cell.
Engineering a freestanding biomimetic cardiac patch using biodegradable poly(lactic-co-glycolic acid) (PLGA) and human embryonic stem cell-derived ventricular cardiomyocytes (hESC-VCMs).

The voltage sensitivity of fluorescence of an aminobenzstyryl-pyridinium dye (di4-ANEPPS) is characterized in Retzius cells dissociated from the leech. The modulation of the complete spectra of excitation and emission is determined. The spectral changes induced by depolarization are described by
Excitable media can support spiral waves rotating around an organizing centre. Spiral waves have been discovered in different types of autocatalytic chemical reactions and in biological systems. The so-called 're-entrant excitation' of myocardial cells, causing the most dangerous cardiac arrhythmias

Sarcomere length (SL) is an important determinant and indicator of cardiac mechanical function; however, techniques for measuring SL in living, intact tissue are limited. Here, we present a technique that uses two-photon microscopy to directly image striations of living cells
Long-term synaptic plasticity is thought to provide the substrate for adaptive computation in brain circuits but very little is known about its spatiotemporal organization. Here, we combined multi-spot two-photon laser microscopy in rat cerebellar slices with realistic modeling to map
