Our Research at SMLKI 2026: Colourimetric Detection of Physiologically Relevant Biomarkers on Cellulose-Based Sensors

At the XVI Meeting of Young Chemical Engineers (SMLKI 2026), WearSense project member Iva Karneluti gave a short talk titled “Colourimetric Detection of Physiologically Relevant Biomarkers for Wearable Applications Using Covalently Immobilised Azo Dyes on Cellulose.” The presentation highlighted our work on cellulose-based optical sensors that use covalently immobilised pH-sensitive azo dyes for the detection of physiologically relevant biomarkers. In particular, a colourimetric sensing system for Mg²⁺ ions was demonstrated, along with ongoing work on a printed biosensing platform for urea detection. These results showcase the potential of simple, biocompatible, and low-cost cellulose materials for wearable biosensing applications.
