Huda's first "1+4" female doctor 3D printing technology to detect pesticide residues
Wuhan Evening News, Wuhan, Feb. 11 (correspondent Duan Mengyao reporter Hu Yihua) recently, Wang Yijia, a doctoral student and major in material preparation and testing technology, published an article on Analytical Chemistry (the highest journal in the field of analytical chemistry), using 3D printing technology to detect pesticide residues.
The concept map of the technical model
It is understood that under the guidance of professors Lin Yuehe and Dudan of Washington State University, Wang Yijia's team designed and printed a small optical detection platform with the help of 3D printing technology, using smartphones as information trappers. It can monitor and transmit optical information in real time, and realize real-time monitoring of pesticide 2myr4-dichlorophenoxyacetic acid residues in food, ecological water sources or human metabolic fluids at room temperature.
It is reported that pesticide residues in food and environment have a great impact on human health and environmental protection. Pesticide residues in the surface of grains and vegetables or drinking water, after ingestion of the human body, will have a great impact on health. High concentrations of pesticides can even cause acute poisoning, nausea, vomiting and other adverse reactions.
Most of the traditional pesticide detection methods are time-consuming and labor-consuming, and sometimes expensive large instruments are needed to detect pesticide residues effectively. Wang Yijia's team combined with the gradual development of smartphones, using the smartphone's own voice control system, high-definition parameters adjustable cameras and temperature sensors to use 3D printing technology to detect pesticide residues.
"the scheme fails before it succeeds, and 99% of our experiments are failed." Wang Yijia said, "every time we fail, we are constantly modifying the plan, slowly groping and optimizing the experimental conditions to get good results."
The top journal paper knowledge platform X-MOL spoke highly of the device: "the device is not only high sensitivity, but also low cost, small size, light weight, and can even realize real-time monitoring of pesticide residues in environmental samples. The device is compact and portable, which not only saves the detection cost, but also achieves accurate and reliable results, realizes the convenient application of smart phones in daily life, and is of great significance to promote the development and construction of smart phone detection devices.
