Abstract:
This study demonstrates the application feasibility of electrochemical impedance spectroscopy (EIS) in measuring estrogen (17 β -estradiol) in gas phase. The present biosensor gives a linear response ( R 2 = 0.999 ) for 17 β -estradiol vapor concentration from 3.7 ng/L to 3.7 × 10 −4 ng/L with a limit of detection (3.7 × 10 −4 ng/L). The results show that the fabricated biosensor demonstrates better detection limit of 17 β -estradiol in gas phase than the previous report with GC-MS method. This estrogen biosensor has many potential applications for on-site detection of a variety of endocrine disrupting compounds (EDCs) in the gas phase.
