New developments in biosensor design are appearing at a high rate as these devices play increasingly important roles in daily life. This review aims to highlight recent developments in materials and techniques for electrochemical biosensor design and construction. Rapid growth in biomaterials, especially the availability and application of a vast range of polymers and copolymers associated with new sensing techniques have led to remarkable innovation in the design and construction of biosensors, significant improvements in sensor function and the emergence of new types of biosensor. Nevertheless, in vivo applications remain limited by functional deterioration due to surface fouling by biological components. However, new copolymers based upon biomembrane mimicry have been extensively investigated during the last two decades, raising hopes that the problems related to interactions between foreign surfaces and biological fluids and tissues may soon be solved.
