Resumen:
We report an optofluidic technique for local and instantaneous determination of pore opening during dissolution of barrier oxide layer in nanoporous anodic alumina membrane. The reflected light from a focused laser on the sample can be used to monitor the capillary imbibition of the etching solution. Since the etching rate increase with the temperature, the same laser used to measure the pore opening process can be used to control the area of the sample were the pore opening occurs first.
