Soap film is formed by blowing soap bubbles just like what kids do.
Weigh it? I don't know what precision do you need, but the simplest method that came into my mind is to weigh the frame than weigh the frame with film and divide the difference by water density and surface of the frame.
One word: Refraction
Polymer microparticles (such as PLGA) with different diameter in the range of several micrometers to tens of micrometers are mixed together. If we want to collect them in different size range, are...
