Disclosed is a method of forming a conductive polymer thin film pattern, including (a) Coating substrate with solution including PEDOT:PSS (poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)) to form coating layer including solution on substrate, (b) irradiating a predetermined portion of the coating layer with light, thus manufacturing a pre-patterned substrate including PEDOT:PSS patterned on the predetermined portion and the coating layer other than the predetermined portion, and (c) removing the coating layer from the pre-patterned substrate, thus manufacturing a conductive polymer thin film having a PEDOT:PSS pattern. When the pattern formation method of the invention is applied, a pattern can be formed by directly irradiating a PEDOT:PSS solution with a laser, there is no need for additional drying, thus simplifying the processing and reducing the processing time, and a thin film for use in a transparent electrode can be manufactured, thereby improving the conductivity, transmittance, flatness and precision of the electrode.

Organometallic redox mediator compounds, such as substituted ferrocenes or other metallocenes, and redox polymers comprising the organometallic redox mediators are described. The organic groups of the organometallic redox mediators can be substituted with multiple (e.g., at least three or at least four) electron-donating substituents, which can reduce the redox potential of the redox mediator compared to the corresponding unsubstituted redox mediator. Electrodes coated with the redox polymers or blends comprising the redox polymers are described, as are related electrochemical sensors. In addition, methods of using the sensors to detect biological analytes of interest, such as glucose or ketones, are described.
