Bacterial Cellulose-Based Laser-Scribed Graphene Electrode for Hydrogen Peroxide Detection in Cancer Cells.

ABSTRACT: The development of sustainable and high-performance electrochemical sensors is crucial for advancing biomedical applications. In this work, we introduce a hydrogen peroxide (H₂O₂) sensor based on bacterial cellulose-derived laser-scribed graphene (BC-LSG), modified with MXene and platinum nanoparticles (PtNPs). Bacterial cellulose (BC), a biodegradable and renewable material, was cultivated and transformed into a highly conductive carbon network using CO₂ laser irradiation, producing a flexible, portable, and miniaturized electrochemical platform. The incorporation of MXene and PtNPs significantly enhanced the electrocatalytic response toward H₂O₂ oxidation, achieving a wide linear concentration range (15-95 μmol L^-1) and a
