Lowering the size detection limits of Ag and TiO2 nanoparticles by Single Particle ICP-MS.

Analytical Chemistry, 2019
As the production and use of engineered nanomaterials increases, there is an urgent need to develop analytical techniques that are sufficiently sensitive to be able to measure the very small nanoparticles (NP) at very low concentrations. Although, Single

ICP-MS

Alzheimer Disease & Associated Disorders, 1988
It has been known for over 100 years that trace elements play an essential role in metabolism. Some 24 elements are now acknowledged as being essential to life. Many conditions have been examined in recent years from a trace element viewpoint. Alzheimer's disease and the part played by aluminium has received much attention, particularly since Crapper's
