Abstract: A mobile device for detecting pesticides in a sample such an agricultural product by a method of Surface-enhanced Raman spectroscopy (SERS) includes: a feeder for raw material, a container for processing the raw material into the required form, a feeder for nanomaterials in the liquid phase, a feeder for nanomaterials in solid phase—substrates with nanomaterials, a container for preparing a sample for measurement, a platform for moving samples in containers or vessels for measurement, Raman spectrometer and a measuring chamber. A related method detects pesticides in a sample of an agricultural product with a mobile device.

Abstract: A device for the production of nanoparticles in situ for Surface-enhanced Raman spectroscopy in a mobile measurement station includes a least a first block having a control system, an automatic titration and dosing system, containers for substances with a system supplying substances to a reactor, a chemical reactor with a substance stirring system, sensors for controlling the nanomaterial production process, a heating and process temperature control system, a system for conducting the produced material to the next block outside, a nanoparticle processing system to perform measurements. A related method produces nanoparticles in situ for Surface-enhanced Raman spectroscopy in a mobile measurement station.
