Low-cost glucose sensor component matches pricier option at a tenth of the cost

Researchers at Texas A&M University have found a much cheaper material for an experimental injectable glucose sensor that performs about as well as a far pricier alternative. The team used beta-mannopentaose instead of the alpha-mannopentaose used in earlier versions, in a nonenzymatic sensor that tracks glucose through fluorescent signals. The sensing chemistry was placed in a small hydrogel designed to sit under the skin, and in testing it kept more than 94 percent of its sensing assay over seven days. The work is still at the proof-of-concept stage and is not yet ready for clinical use.
