1. A method for the detection and screening of plastic microparticles, the method comprising the steps of:
delivering a sample through a nanoporous silicon nitride membrane;
entrapping on the nanoporous silicon nitride membrane microparticles contained in the sample;
providing an increasing temperature profile to the silicon nitride membrane;
observing a phase change of the entrapped microparticles; and
recording the temperature at which the entrapped microparticles change phase.
