Food Supply Chain Analytics and Sensing Initiative

Sensor Development

In order to meet the pace and volume of food supply chain monitoring, we aim to develop an innovative, inexpensive, and portable multiplexed sensor platform capable of quantitative measurement of heavy metals, antibiotics, and drug residues on-site. The multiplexed nature of the platform will allow for detection of multiple contaminants in real-time.
Our approach involve using nanoparticles that can report analyte presence through changes in optical signal. These particles are cheap to produce and are stable under a wide range of storage conditions. Specific molecular recognition is being engineered in two ways: 1) non-covalent attachment of polymers to the particle, and 2) attachment of nanobodies, a biological recognition molecule, to the nanomaterial transducer.
