Microfluidic desorption-free magnetic solid phase extraction of Hg2+ from biological samples using cysteine-coated gold-magnetite core-shell nanoparticles prior to its …
The authors describe a microfluidic method for desorption-free magnetic solid phase
extraction (MSPE) of Hg 2+ ions prior to their determination through ICP-MS. Nanoparticles
comprising a gold core and an iron oxide (Fe 3 O 4) shell were functionalized with l-cysteine
and then used to extract trace amounts of Hg 2+. In contrast to typical solid phase extraction
processes, this approach is rapid and does not require a desorption step. The working pH,
amount of adsorbent, sample volume, adsorption selectivity, adsorption capacity, and …
