Today marks a major milestone in optical biosensing – the successful development of a dual high-resolution surface plasmon resonance (SPR) system. This new system, developed by scientists from the University of New South Wales (UNSW) and the University of Technology Sydney (UTS), is capable of detecting two different biomolecules simultaneously, with a resolution of up to 0.01 nanometres. This opens up the potential for improved sensing capabilities in a range of areas such as medical diagnostics, food safety, environmental monitoring and drug development. The team’s work has been published in the journal Nature Photonics.
