Carbon nanosensor could improve testing for histamines in food

Histamines detected in food

Researchers from Northwestern University (IL, USA) and Iowa State University (IA, USA), have developed a carbon nanomaterial-based electrochemical sensor capable of detecting histamines and other toxins in food at a significantly faster rate than existing tests. This has implications for human health as it could reduce the likelihood of foodborne diseases.  The researchers developed an aerosol-jet printable graphene ink to create their sensor. This allowed for fast changes to the pattern geometry on demand through the software that enabled rapid prototyping and efficient optimization of the device design. Carmen Gomes, senior author from Iowa State University, described: “Aerosol-jet printing was...
