Use of Functional Nanomaterials in Biosensors

Rukan Genc

Resumen


The subject of the proposed chapter is to discuss aspects of the implementation of nanomaterials in biosensors. The integration of nanomaterials into biosensing systems represents one of the hottest topics of the todays research and wide range of nanoscale materials of different sizes, shapes and compositions are now available.  Unique properties possesed by nanoscale materials as a result of their tailored nano size and structure which offer excellent prospects for designing novel sensing systems and enhancing the performance of the biorecognition system with proved electronic signal transduction.

The immobilization of nanomaterials onto sensing devices and/or building sensor platforms using buttom-up approaches generates novel interfaces that enable optical or electrochemical detection of the biomolecule of whim with enhanced sensivity.  Moreover,  nanomaterials are being used as effective labels which role as signal amplifier to increase the sensor sensivity and add  controlled functions with interest for several applications.

State of the art related to functional biosensor platforms formed of nanoparticles, nanotubes, nanowires and nanochannels explaining the afore mentioned futures will also be given.  Moreover, many other aspects asscociated to the advantages offered by nanomaterials, the challenges and drawbacks, and real world applications of these kinds of biosensors , current status and future prospects will be discussed in detail.
