(725a) Fabrication of Nanobiosensors

Different nanobiosensor fabrication methods are presented and reviewed. The examples of nanobiosensor fabrication presented are selected at random from the literature. These examples have appeared recently in the open literature. Though glucose nanobiosensor fabrication methods presented appear frequently in the literature, other examples of nanobiosensor fabrication are also presented. The nanobiosensor fabrication methods for glucose sensors include: biosensor using a nanocomposite electrode, Safavi et al., 2009; screen-printed water-based carbon-ink microband biosensor; Pemberton et al., 2009; zinc-oxide nanoparticle/glucose oxidase biosensor, Ren et al., 2009; and platinum nanowire array biosensor, Yang et al., 2006). Other fabrication techniques presented include: biosensor fabrication procedure based on processable polyanilione nanoparticles, Morrin et al., 2005; biosensor fabrication based on nanowire microelectrode array, Yang et al., 2006; and recrystallization technologies to fabricate a Si nanowire biosensor, Ashburn et al., 2009). The presentaton of different nanobiosensor fabrication techniques together quickly provides one with an overall perspective of the different fabrication techniques that have appeared in the recent literature, and what techniques exhibit potential, and which techniques are being explored further research wise. The nanofabrication techniques are application dependent, such as the determination of glucose, but as one might reasonably expect, biosensors for the detecton of other analyztes is slowly gaining importance, and thus nanofabrication techniques other than for glucose detection need to be explored further. In a sense, the nanobiosensor fabrication btechniques briefly mentioned here may be considerd loosely as a starting point in an iterative solution, which continually improves with each iteration.
