Flexible Graphene Biosensor for Lactate Analysis


Utah State University researchers have developed a graphene sensor for the analysis of lactic acid. Graphene is a single-atom-thick, sp2 carbon-based material used in developing sensors due to its remarkable electrical, optical, mechanical and thermal properties. This sensor, while bonded to a flexible substrate, provides several advantages within the analysis of lactic acid, a recognized biomarker for a variety of conditions.

  • Medical (surgery)
  • Clinical research involoving saliva, skin or blood
  • Biomarker for diagnostic purposes, e.g., heart failure, liver disease, metabolic disorders, drug toxicity, monitoring ventilated infants, microbial food contamination, etc.

  • Light-weight
  • Flexible
  • Sensitive

Lactic acid is an important analyte for clinical analysis in saliva, on skin or in blood. This technology includes a graphene nano-sensor adhered to a flexible, plastic substrate. The sensor is flexible and light-weight, making it capable of being used a wearable or fixed sensor.
