Its safety for both human health and aquatic biomes is a subject of wide debate. There are limits to glyphosate\u2019s presence in bodies of water, and it is usually detected through complex analytical procedures. In this work, the presence of glyphosate is detected directly through optical interrogation of aqueous solution. For this purpose, silver nanoparticles were produced by pulsed laser ablation in liquids. Limits of detection of 0.9 mg\/L and 3.2 mg\/L were obtained with UV-Vis extinction and Surface Enhanced Raman spectroscopies, respectively. The sensing mechanism was evaluated in the presence of potential interferents as well as with commercial glyphosate-based herbicides.<\/jats:p>","DOI":"10.3390\/s17050954","type":"journal-article","created":{"date-parts":[[2017,4,26]],"date-time":"2017-04-26T13:42:06Z","timestamp":1493214126000},"page":"954","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Spectroscopic Detection of Glyphosate in Water Assisted by Laser-Ablated Silver Nanoparticles"],"prefix":"10.3390","volume":"17","author":[{"given":"Rafael","family":"De G\u00f3es","sequence":"first","affiliation":[{"name":"Graduate Program in Electrical and Computer Engineering (CPGEI), Federal University of Technology-Parana, Curitiba 80230-901, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4463-3526","authenticated-orcid":false,"given":"Marcia","family":"Muller","sequence":"additional","affiliation":[{"name":"Graduate Program in Electrical and Computer Engineering (CPGEI), Federal University of Technology-Parana, Curitiba 80230-901, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5630-1193","authenticated-orcid":false,"given":"Jos\u00e9","family":"Fabris","sequence":"additional","affiliation":[{"name":"Graduate Program in Electrical and Computer Engineering (CPGEI), Federal University of Technology-Parana, Curitiba 80230-901, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,4,26]]},"reference":[{"key":"ref_1","first-page":"17","article-title":"The herbicide glyphosate","volume":"2","author":"Malik","year":"1989","journal-title":"Biofactor"},{"key":"ref_2","first-page":"14","article-title":"Glyphosate, part 1: Toxicology","volume":"15","author":"Cox","year":"1995","journal-title":"J.
