To investigate fluorescence lifetime spectroscopy in tissue-like scattering, measurements of phase modulation as a function of modulation frequency were made using two fluorescent dyes exhibiting single exponential decay kinetics in a 2% intralipid solution. To experimentally simulate fluorescence multiexponential decay

The accumulation of [3H]triphenylmethylphosphonium cation in neuroblastoma N1E 115 cells in the presence of tetraphenylboron is reduced by 3,3'-diethylthiadicarbocyanine iodide and by 3,3'-dipropylthiadicarbocyanine iodide. This reduction in uptake of the lipophilic cation is not due to the carbocyanine dyes depolarizing
