چکیده
|
This study demonstrates the application feasibility of electrochemical impedance spectroscopy (eis) in measuring estrogen (17β-estradiol) in gas phase. the present biosensor gives a linear response (r 2 = 0.999) for 17β-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 17β-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. © 2016 jing li et al.
