A fiber-based optrode modified with a double-layer platinum black-poly (3,4ethylenedioxythiophene) PEDOT/poly (4-styrenesulfonate) PSS (Pt-PP) coating has been developed for improvement of neural recording quality and mitigation of photoelectric artifact simultaneously.
A poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) hydrogel is prepared by thermal treatment of a commercial PEDOT:PSS (PH1000) suspension in 0.1 mol L<sup>-1</sup> sulfuric acid followed by partially removing its PSS component with concentrated sulfuric acid.
Scleroderma (progressive systemic sclerosis; PSS) is a connective tissue disorder in which excessive collagen is deposited in the skin and internal organs.
