With The Smartphone Against Poisons

A novel measuring system that fits to conventional phones, pesticides should sniffs are.

With The Smartphone Against Poisons
Plant protection products containing organic phosphorus compounds are efficient and cheap – but also health and environment. In Europe, they disappeared already from the market. In developing and emerging markets, they are still used in large quantities on the plantations.

It would be better to use alternatives. Until it is however so far, can a new process by Valeria Springer of the Universidad Nacional sur in Argentina prevent at least that the pesticides end up on the table, reports technology review. When exporting, the residues on fruit and cereal ingredients must not exceed a certain amount. To verify that quickly and cheaply, Valeria, Springer developed a system that can be used directly on the plantation.
The detection of the residues is so far quite costly. The samples must be sent to distant Labs and require chromatographic measurements with expensive equipment. In addition, larger quantities of sample are needed. The 27-year old chemist’s analysis kit consists of a tube with the capacity of 1 milliliter. In it are located 20 nanometer-sized Gold nano-particles. Adds a solution extracted from the foods bind the residues of plant protection products to the particles and thus increase their surface area. The result is a color change in the particles from red to violet.
To measure it, the solution with a Smartphone will be photographed, a software analyzes the images. “With my method, the control on the remnants of the syringe is very easy. It can be noted, whether a product complies with international directives”, Springer explained. Currently run first test trials in grain cultivation. So far, the kit of the chemist but only recognizes whether there are any residues. In the next step it to can read out individual pesticides and their quantity.
