A new study has discovered the mystery behind ‘coffee rings’ and how it could advance research in blood diagnostics.
An international research team, led by Monash University, has discovered for the first time the mystery behind the formation of ‘coffee rings’ by examining the contact angle of droplets onto a surface, and how they dry.
The research collaboration involving Monash University and Cambridge University also developed a mathematical model that is capable of predicting when a coffee ring could be observed in hard spherical particle systems.
Professor Gil Garnier, Director of BioPRIA (Bioresource Processing Research Institute of Australia) in the Department of Chemical Engineering at Monash University, led an international team to explore how patterns formed from evaporating droplets – a phenomenon that has mystified physicists for years.
Professor Garnier said this discovery, created by Dr Michael Hertag from BioPRIA, could open up doors in the blood…
