  1. Albumin Analysis by Potentiometric Method

  2. #2 Process of preparing Au wire electrode Seal the electrode by epoxy adhesive excepts the sensing area(wait for a night) Wash by DI water for several times Polish the electrode surface by polishing paper (1500 mesh) Dry by N2(g) Clean the electrode by ultrasonic for 3 min. Dip into 1N HCl(aq)for 10min. Wash by DI water for several times wipe by delicate task wiper Dip into 1N NaOH(aq)for 10min.

  3. #2 Process of preparing Au wire electrode Dry by N2(g) Dip in 10ml DI water for 20sec. for five times Dip into 1N HNO3(aq)for 10min. Dry by N2(g) Wash by DI water for several times Dip into 0.1ml albumin(aq/0.5M KCl for a setting period. Dry by N2(g) Wash by DI water for several times Scan C-V (0ppm)

  4. #2 Process of preparing Au wire electrode Dry by N2(g) Wash by DI water for several times Scan C-V Dry by N2(g) Dip into 10ml DI water for 20sec. for five times Dip into 1N HCl(aq)for 10min. Dry by N2(g) Wash by DI water for several times Dip into 1N NaOH(aq)for 10min.

  5. #2 Process of preparing Au wire electrode Dry by N2(g) Dip into 1N HNO3(aq)for 10min. Wash by DI water for several times Dry by N2(g) Scan C-V
