![]() ![]() They turned to SERS spectroscopy, an analytical technique which provides information about chemical composition by analyzing the light that molecules scattered when adsorbed on the sensor’s surface. However, these methods can be expensive and sometimes time-consuming, requiring trained staff to carry out the analysis.īut the collaborative team based in Scotland, Portugal, and Germany, took an alternative approach. “We have been working for several years and, of late, on novel -enabled surface-enhanced Raman scattering (SERS) sensors to detect pollutants such as pesticides, antibiotics, and biomolecules in water,” he continued.Ĭurrently, conventional analytical techniques, such as high-performance liquid chromatography, gas chromatography, and mass spectrometry, are used for detecting pollutants in samples collected from the field. “In the last decade, efforts have been made to develop novel nanomaterials, techniques, and cheaper systems for monitoring and decontaminating water,” said Shanmugam Kumar, a professor of composite materials and advanced manufacturing in the James Watt School of Engineering at the University of Glasgow, and one of the study’s lead authors. In it, researchers report developing a cost-effective, and portable 3D-printed sensor with unprecedented sensitivity that allows it to detect exceedingly low concentrations of pesticides in water samples. However, to do this effectively requires advanced, portable sensor technologies that are capable of detecting even the tiniest traces of contaminants.Īddressing this critical need, a study published in Macromolecular Materials and Engineering introduces a remarkable advancement in water pollution sensing. Monitoring water pollution is of the utmost importance to maintaining ecosystems, safeguarding human health, and ensuring the sustainable use of water resources.
