Development of Novel Gold/PDMS Sensors for Medical Applications

Abstract

The paper presents the design and fabrication of novel gold/PDMS sensors using the sputtering method to use them for biomedical applications. The electrodes on the sensor patches were formed by placing a masked template containing the design over the PDMS. The sensor patches were flexible in nature with interdigitated electrodes formed on them. CTx-I, being one of the significant bone turnover biomarkers to determine the condition of the bones was tested at different concentrations to validate the functionality of the patches for this purpose. The results look promising to upgrade this idea into a fully-functionalized system for medical applications.
