“…Electroscavenging has already been used by Suh et al to apply larger numbers of elementary charges to nanoparticles for use in nanoparticle pattern structures. 12 The way this process works is that solvent vapor is first condensed on the particles in a device known as a particle magnifier. The droplets containing the particles are then charged with a corona wire.…”

The Charging of Micellar Nanoparticles in Electrospray Ionization

et al. 2013

View full text Add to dashboard Cite

Charging of nanoparticles through electrospray has scarcely been explored. Spherical nanometer-sized amphiphilic block copolymer nanoparticles with diameters ranging from ∼65 to ∼150 nm were electrosprayed and analysed by charge detection spectrometry. Herein, we explore the charging of these micellar nano-objects by conducting a thorough study in different solvents, including pure water, and upon the addition of "supercharging" agents. The charge (z) of micellar nanoparticles electrosprayed from water solution is compared to the Rayleigh's limiting charge (z(R)) of a charged water droplet of the same dimensions. An average ratio (z/z(R)) of 0.6-0.65 is observed for the micellar macro-ions, supporting the charge residue mechanism, where the number of charges available to the micellar macro-ion is limited by the number of charges on the nanodroplet, which is a function of the surface tension of the solvent. Also we show the possibility of increasing the charging of micellar nanoparticles in the negative mode by adding organic bases (in particular piperidine) to water/methanol solutions.
