Estimating the mechanical properties of retinal tissue using contact angle measurements of a spreading droplet

Recently published in arguably the premier journal in the field of interfaces, colloids and physical chemistry, this Medical Research Council funded (Project G0802583) multidisciplinary collaboration of physicists, engineers and a consultant vitreo-retinal surgeon establishes a new technique for determining the mechanical properties of soft biological materials such as retinas. Characterising such tissue is vital for research into developing less invasive treatments for retinal problems, but is extremely difficult using e.g. atomic force microscopy. The work led to further funding from the Yorkshire branch of the National Eye Research Centre as pump-priming for a larger MRC application.
