• form
  • On its own, however, this form of colorimetry, known as gold nanoparticle aggregation-based colorimetry (AuNP-ABC), can't be used to detect specific analytes in complex samples, because the gold nanoparticles will interact with any positively-charged analytes. (separationsnow.com)
  • Test
  • As a first test of this combination of CE and colorimetry, Qin and his colleagues tried using it to separate and detect three polyamidoamine (PAMAM) dendrimers, which are being developed as drug delivery vehicles, in diluted urine. (separationsnow.com)
  • Qin and his colleagues are now looking to test this combination of CE and colorimetry on other positively-charged analytes in complex samples. (separationsnow.com)
