We are delighted to highlight the latest covers of Analyst, showing new research on the development and application of a sensory system to detect glucose.
John Fossey from the University Birmingham, UK, and collaborators at the University of Bath, UK, and at the East China University of Science and Technology, China, present two papers describing a new glucose sensor based on the principle of self-assembly and surface plasmon resonance (SPR) optical technique.
The sensor is prepared modifying the surface of a gold electrode with a bis-boronic acid receptor. The receptor contains a glucose selective chemosensor unit and a surface anchoring unit, which allows selective detection of glucose. This system has the unique capacity to label-free and allows detection of molecular reactions in real time with highly sensitivity. According to this research, SPR could be an attractive sensing platform to monitor glucose and possibly other analytes.
