- Abstract
We present the results of research and development of photonic sensors based on nanoporous silicon (pSi), which are used for determination of low concentration of atrazine and alpha (α); beta (β) isomer endosulfan concentration in aquatic environment. The limit of detection (LOD) of sensors is of 1.4 pg.mL, 0.32 μg.mL and 0.21 μg.mL for atrazine and α- and β-endosulfan, respectively. Experiment shows that atrazine's half-life in the aqueous phase ranges from 60 to 150 days in the humic acid and/or water, respectively. These pSi-sensors can contribute to the detection of persistent pesticides in the aqueous medium with short measuring time and high sensitivity for improving agricultural and food productions with sustainable environmental protection.
