New synthesis of silica nanoparticles

New synthesis of silica nanoparticles

Silica nanoparticles can now be easily developed and efficiently used in bioassays. This study just published in JAAS by Jung Aa Ko and H. B. Lim shows the design and optimisation of a new method for synthesis of core-shell nanoparticles doped with metal ions and dye together for particle tagging and monitoring.

Precise measurements of platinum stable isotopes

Measuring platinum stable isotopes

Researchers at the Victoria University of Wellington, New Zealand, present the precise measurement of platinum (Pt) stable isotopes by multiple collector inductively coupled plasma mass spectrometry (MC-ICPMS) using two diffrerent double spikes. The authors explain that the 196Pt-198Pt spike is preferable for application to both natural terrestrial and extraterrestrial samples.
