Genetically modified organisms, or GMOs, are subject to strict regulation. In a paper entitled “ An Additive Manufacturing Approach that Enables the Field Deployment of Synthetic Biosensors ,” a group of researchers explains that living biosensors, which can be deployed for disease diagnosis in the field, are considered GMOs and are therefore subject to that same regulation. Using 3D printing is one way in which these biosensors can be made secure and acceptable for deployment in the field. In rural and less-developed areas, the researchers explain, the pathogen P. aeruginosa can be acquired in local clinics. The organism is found in lung sputum samples upon infection, and the samples can be collected and placed in commercially available sample tubes. The researchers’ study focuses on creating a biosensor that could be used to immediately diagnose the disease in the field. They used E. coli as a biosensor, but needed a […]
