| Abstract Scope |
Precise synthesis and integration of nanomaterials are key to advancing wearable biosensing technologies. This work introduces a unified material strategy using laser-induced graphene (LIG) and functional nanocomposites to develop a highly sensitive, skin-conformal, and long-term stable platform for real-time biomarker detection in sweat. By applying direct laser processing to polymeric and composite substrates, we create porous, conductive graphene-based structures with tunable surface properties. Functionalization of LIG with metallic nanocomposites enables excellent electrochemical sensitivity and specificity, even under varying physiological conditions. A multifunctional, intrinsically adhesive composite further simplifies integration of sensing and power components without additional adhesives or complex fabrication. This approach enables the scalable production of soft, stretchable devices capable of continuous, non-invasive monitoring of sweat biomarkers. Together, these innovations highlight how controlled nanomaterial synthesis and processing can drive practical applications in health diagnostics and personalized medicine, offering a promising path toward the next generation of intelligent, body-integrated sensing systems. |
