An important class of nanoparticles made of “upconversion” materials has found a central role in sensing. These nanoparticles are used to convert longer-wavelength photons into shorter-wavelength fluorescence to detect temperature, pH, gas molecules, ions, and trace biomolecules.

This study shows, for the first time, that limits of detection (LOD) can be improved for P, S and Ca nanoparticles by the addition of N2 to the plasma flow for single-particle inductively coupled plasma–mass spectrometry (spICP-MS). The work also examined the relative LOD differences using Ar-N2 and Ar-N2-H2 mixed-gas plasmas.
