Much recent research has focused on electrochemical biosensors to meet the growing demands for rapid and accurate diagnostic tests for diseases, detecting toxic molecules present in the environment, and biomolecules used as in pharmaceuticals. Carbon nanotubes (CNTs) have been shown to be effective for electrochemical biosensors because of their favorable chemical, physical and electrical properties. Here we report the use of a two-dimensional entangled mat of CNTs, known as buckypaper, as electrodes for electrochemical biosensors.

Glucose oxidase was immobilized onto various buckypaper samples in order to oxidize glucose resulting in a measureable current/voltage signal output of the biosensor. Cyclic voltammetry (CV) and amperometry were utilized to determine the sensitivity of these buckypaper electrodes.

It is reported that an increase in tumor temperature decreases the tumor resistance to chemo- and radiation therapies. Self controlled heating at the tumor site to avoid spot heating is managed by controlling the Curie temperature of the magnetic particles.
