A group of engineers from DL ADV-Tech and Washington State University (WSU) developed an economical device equipped with a sensor that uses nano-sized tubes to measure the amount of herbicide in the food items. Glyphosate, a commonly used herbicide, has been approved by many regulatory bodies for its use in various eatables. However, the herbicide exhibits hazardous effects on health and the environment. Moreover, the World Health Organization has enlisted this product as a potential carcinogen. The glyphosate sensing technology in the sensor is based on the principle of glucose tests used to measure sugar levels in the blood.

The research comprised of designing a glyphosate monitoring sensor in various eatables is published inthe renowned journal Biosensors and Bioelectronics. The engineers mentioned that this concept of developing such an innovative sensor surfaced as not only conventional methods of herbicide detection in eatables but also complex and expensive. Moreover, additional care of the traditional sophisticated equipment and reagents is required.

Yuehe Lin, who is a professor in the department of WSU, mentioned that the development and commercialization of novel glyphosate sensors would play a crucial role in food safety and environment monitoring. This handy sensor is built by incorporating 3D printing technology to make it compact. Being portable, it can be employed anywhere whether in the field or the lab. The research team explains that these synthetic antibody-based sensors were developed by using conductive polymer nanotubes having molecule-sized cavities to bind glyphosate molecules. Additionally, a 3D coating is provided on the sensor device. The sensor was tested on rice beverages and orange juice with known levels of glyphosate.

Further in the interview, Shichao Ding, a WSU postdoc candidate, mentioned that the team is hoping to use these sensors to detect glyphosate in samples such as blood, urine, or saliva. The engineers are optimistic and engaged in developing more superior nanomaterials to enhance the performance of the sensor.
