Ultrasensitive electrochemical immunosensors for multiplexed determination using mesoporous platinum nanoparticles as nonenzymatic labels

- Mesoporous platinum nanoparticles as a new kind of nanomaterial, has high conductivity and electrocatalytic activity.
- The immunosensor array was proposed for simultaneous detection of three kinds of tumor markers related breast cancer.
- This was a unique realization of a nonenzymatic, which did not use natural enzyme or electrochemical redox mediator.
