Most hormones, such as estrogen, testosterone, and cortisol, can be detected in the blood to diagnose disease. However, the blood draw process is invasive and makes the patient uncomfortable. Thus, there is an increasing interest in the detection for long-time analysis in a non-invasive manner. In this study, a composite of polyethylene glycol (PEG) and Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)-based conductive hydrogels was prepared as sensing base materials to enable non-invasive diagnosis. PEG is a biocompatible material that allows the patch-type sensor to absorb hormones, and conductive PEDOT:PSS enables the detection of hormones electrochemically. The flexibility, absorption capacity, conductivity, and biosafety of the conductive hydrogel were confirmed through hardness, swelling behavior, voltage application and cytotoxicity tests. This is expected to enable faster and simpler disease diagnosis by detecting various hormones. |
