Enhanced Microbial Sensing via Resazurin Reduction Catalyzed by Graphene Oxide, A Versatile Approach for Diagnostics and Electrochemical Applications

Environmental Toxicology, Volume 41, Issue 4, Page 223-232, April 2026.
ABSTRACT Resazurin is a cell viability phenoxazine dye widely employed for bacterial monitoring, as its colorimetric and fluorometric conversion reflects microbial metabolic activity. In this work, we demonstrate that graphene oxide (GO), a two‐dimensional nanomaterial with high surface reactivity, markedly accelerates the reduction of resazurin in the

A One‐Step Workflow for Size‐Based Separation of Extracellular Vesicles With Integrated Surface Marker Detection

Journal of Extracellular Biology, Volume 5, Issue 3, March 2026.
ABSTRACT Extracellular vesicles (EVs) are released by diverse cell types in biofluids and are increasingly studied in liquid biopsies as diagnostic and prognostic biomarkers for various diseases, including cancer. Typically, the analysis of EV‐associated biomarker characteristics such as size and surface markers requires pre‐purification from large ...

Development of Functional Coatings from PCL‐PEG Tetra‐Arm Amphiphilic Polymer Co‐Networks with Enhanced Cell Adhesion

Macromolecular Chemistry and Physics, Volume 227, Issue 5, 13 March 2026.
PCL‐PEG based ACN thin films provide a highly tunable biointerface, where PEG content governs morphology, protein adsorption, and cellular responses. PEG‐lean films support fibroblast adhesion and proliferation, while PEG‐rich films are non‐cell‐adhesive with low protein adsorption, reversible by dECM coating.
