posted on 2016-02-20, 18:02 authored by Oscar Filevich, Guillermo Carrone, Victoria Andino Pavlovsky, Roberto EtcheniqueWe describe a complete system for optical pH manipulation
and imaging.
The system consists of a photoactive Ruthenium complex capable of
inducing a change of more than 5 pH units at the nanosecond time scale.
A compatible imaging system acquires microscopic pH images at 1200
fps using a nonexpensive commercial digital camera and an LED illumination
system. We use the system as a superb tool to investigate flow in
Flow Injection Analysis (FIA) models.
