Woo Soo Kim and co-workers have developed eco-friendly, 3D-printed disposable sensor devices using biocompatible cellulose nano-fiber-based ink materials. These innovative devices feature a smart 3D form factor and incorporate highly sensitive wireless ion-selective sensors for the first time. This novel wireless chemical sensing platform is expected to revolutionize various applications, including biomedical and environmental detection.-Scientific Journal cover design by scapiens
