Journal 
of Materials Chemistry A, B and C were delighted to sponsor a poster prize at the Materials Chemistry Poster Symposium on the 29th November. Oliver Hagger from University College London won the prize for his poster titled: Rapid single step multi-metal plasma deposition and regeneration of SERS active substrates.
Oliver Hagger is a PhD researcher in the Department of Chemistry at University College London (UCL) in collaboration with the Defence Science and Technology Laboratory (Dstl). He completed his MChem at the University of Southampton in 2020, which included a secondment at Brown University. His research focuses on utilising atmospheric pressure plasma jets (APPJs) to selectively deposit zero-valent metals on a variety of solid substrates. He has demonstrated the ability to use these metal deposits to analyse atmospheric and liquid-borne analytes through surface-enhanced Raman scattering (SERS). Notably, he has shown how plasma can be employed to selectively ‘clean’ SERS substrates to restore baseline, enabling their reusability and potential for continuous monitoring applications. This innovative work is highlighted in a recent publication in the RSC journal Materials Advances.
