A) Electrode array of the wave-like interdigitated electrode sensor, Low magnification at 100× and the high magnification shows 30 μm finger and spacing in detail B) DTSP is functionalized upon the e IDWμE modified wave shaped electrode, which allows for the immobilization of the anti-CRP antibody C) EGOFET sensor submerged in PBS where 1) anti CRP immobilized by P3HT surface 2) pTHMMAA absorbed by surface where anti-CRP is not present to prevent nonspecific binding 3) CRP binds to anti-CRP, producing an electrical current. D) The functionalization of DTSP, anti-CRP immobilization, and attachment between CRP and anti-CRP, respectively. A) B) C) and D) Reprinted and adapted with permission from Ref. [89].
