Light from interior of bubbles and radicals reacting with luminol in a micro sonoreactor

What is it about?

We measured the light resulting from cavitation events (collapses of bubbles) and the luminescence of luminol reacting with radicals (as a result of water molecule breaking inside the bubbles when imploding).

Why is it important?

This is a method to extract information from the population of bubbles in a non-invasive way and without the need of fast imaging techniques. This was the first time that such sonochemical reactors were studied In microfluidic settings.
