Detection at the nanoscale: A phosphate-detecting electrochemical sensor
A research team led by Suprem Das at Kansas State University has developed a novel electrochemical sensor that can detect phosphate molecules in water using printed graphene. The sensor is the first of its kind and has the potential to advance sensing technologies. The team's work has earned Das his fourth patent and further advances graphene's potential in various applications.
- ▪The sensor uses printed graphene to detect phosphate molecules in water.
- ▪The technology works by applying a small electrical voltage to the sensor surface, enabling the detection and quantification of phosphate molecules.
- ▪The research team has tested samples over several months and received consistent results.
