electronifty jello concentrates body fluid making tests more accurate

thinking about pee tests I thought of a way to make them more effective, actually this could work with a variety of fluids.

Use polymethylmethacrylate gel to absorb all the pure water of a sample then the chemicals being measured could be concentrated 20 times.

One approach to making sure the preferrred protein stays at solution is to use the isoelectric point of the protein. Thats the place at gel electrophoresis where a particular band of protein likes to go. It has an electron affinity pH equivalent(link). Thus making the PMMA gel at a slightly different than isolectric pH would tend to keep the protein from adsorbing or absorbing Another approach is to make the PMMA get an electret that simply repels proteins of same charge to keep them at the solution.

Going further you could place a PTFE coating with water only micropores on the surface to make sure the PMMA just absorbed water molecules.

These approaches should work with other body fluids as well, making a variety of physical tests more accurate or faster.

Polymethylmethacrylate is pretty cheap its the superabsorber at diapers, thus a thing like the 2 or 3¢ birth defect screening test wetnap could actually have a coating or area of PMMA on rather cheaply. That could matter for a retest.
