Epoxy graphite composites

Biocomposites can also be easily prepared by adding the bioreceptor (an enzyme [18] and antibody [23], or an affinity receptor such as Protein A [73] or avidin [74,75]). 

The GEC-based transducers present numerous advantages over more traditional carbon-based materials higher sensitivity, robustness, and rigidity. Additionally, the surface of GEC can be regenerated by a simple polishing procedure. 

An ideal material for electrochemical genosensing should allow an effective immobilization of the probe on its surface, a robust hybridization of the target with the probe, a negligible non-specific

Several experiments will now be described from which the foregoing basic stiffness and strength information can be obtained. For many, but not all, composite materials, the stress-strain behavior is linear from zero load to the ultimate or fracture load. Such linear behavior is typical for glass-epoxy composite materials and is quite reasonable for boron-epoxy and graphite-epoxy composite materials except for the shear behavior that is very nonlinear to fracture.
