SERS Sensing of Pollutants and Pesticides

Ag NPs was the possibility of detecting the polyaromatic hydrocarbons mixtures or multicomplex system without any pretreatment (Guerrini et al. 2011). 

Some authors reported the combination of SERS with the separation methods (Hobro and Lendl 2011). For example, Carrillo-Carrion and co-workers reported a combination of liquid chromatography (LC) and SERS on Ag-quantum dots sponge shaped stmctores for pesticide identification (Carrillo-Carrion et al. 2012). A microdispenser was used as a method for the separation, identification and quantification of various pesticides, such as chlortoluron, atrazine, diuron and ter-buthylazine. SERS spectra were collected from spots at different amounts injected in the LC column. Very low LODs between 10 and 20 pg were achieved.
