I am looking forward to the day that the research gets into the
public domain (someone else does some looking and reports it to the
Internet),and a known source for the appropriate (clean) brush...

A simple experiment you could do at home is take a dusty surface and
lightly brush it once with a grounded nylon brush (ground it by touching
it to a bare metal source) from an art store, then visually ascertain
the amount of dust remaining after the stroke.

Then repeat the experiment with the same brush in another area, but this
time "charge" the brush electrostatically with a long blast of air from
a can of compressed air.

Theoretically, the "charged" brush should do a better job of lifting
dust by attracting dust particles.

Let us know the outcome ...
