Hi David,
we have used voltage sensitive dyes for this (Di-8-ANEPPS).
Huser, J.; Lipp, P.; Niggli, E.. 1996. Confocal microscopic detection of
potential-sensitive dyes used to reveal loss of voltage control during
patch-clamp experiments. Pflugers Archiv - European Journal of
Physiology 433: 194-199
Good luck
