Recently, ultrasensitive, selective, and recyclable sensor frame has attracted an interest due to the emergence of new toxic chemicals, horrible weapons, and formidable diseases. In this presentation, non-toxic and environmentally friendly hydrogel based on agarose was employed as a sensor framework to prepare a solid and reusable sensor. Hydrogel matrix was produced by a simple reaction and a convenient heat treatment process. In order to enhance signal transduction process, conductive nanomaterials were incorporated along with hydrogel. Owing to the constructed sensor, an important brain hormone, dopamine was monitored with ultrahigh sensitivity and selectivity. It was revealed remarkably that hydrogel was eligible for sensors showing both biocompatibility and reusability. In addition, this study also demonstrated that the sensing medium could be recycled after simple removal of hydrogel without significant sacrifice of sensor performance. |
