SERS Substrate Fabrication via Rapid Triboelectrification‐Driven Self‐Assembly of Close‐Packed Colloidal Monolayers Triboelectrification-driven self-assembly of dry colloidal powder offers a promising dry approach to rapidly (<20$<20$ s) attain ordered monolayer colloidal particles for surface-enhanced Raman spect....

Our #OA article on #SERS substrates is online in #SmallMethods. These substrates are made using #tribocharged #colloidal #assembly of #ordered #monolayers. #sensing #particletechnology #contactelectrification #analyticalchemistry #granularcharging. Link: onlinelibrary.wiley.com/doi/10.1002/...

We also had a lot of fun testing these at the RMIT #FLAMME Lab - showing how these work for next-generation PPE for first responders.
