Expanded use of engineered nanoparticles in consumer products and drug delivery increases the potential for environmental release, overexposure or unintended biological exposure. As a result, extraction techniques with integrated measurement capabilities are needed to accurately and safely extract samples to quantify nanoparticle size, mass, and particle number distributions in biological matrices.  However, removing nanoparticle by-type from biological substrates has proven difficult, in that surface chemistry … Continue reading New technique can remove nanoparticles unaltered from blood with ease.
