Bio-synthesized copper nanoparticle anchored ultrathin petal-shaped black phosphorous nanosheets and 3D graphene decorated nanocomposite for electrochemical sensing of methotrexate and paracetamol in diverse matrices

Creating a sensor that can concurrently monitor multiple therapeutic drugs in complex media is a challenging yet essential endeavor. This study presents a novel biomolecule-free electrochemical platform for simultaneous and highly selective detection of methotrexate (MTR) and paracetamol (PRC) in various matrices, including pharmaceutical formulations, simulated blood samples, and water samples. The platform utilizes a multi-layered …
