MnO Tetrahedral with Carbonyldiimidazole Nanoflower Deposition on Laser-Scribed Graphene for Selective Bio-Capture.

Dengue fever, a mosquito-borne viral infection, poses a significant global health challenge, particularly in tropical and subtropical regions. The absence of non-effective vaccines and specific treatments underscores the need for advanced diagnostic tools for early detection and management. This study presents a novel biosensor for detecting dengue virus type 4 (DENV-4) by combining carbonyldiimidazole nanoflower (CDI-NF) with MnO on laser-scribed graphene (LSG).
