Nanotechnology in Biodevices

Abstract

Nanotechnology is the creation and utilization ofmaterials, devices, and systems through the control of materon the nanometer. The technology has been applied tobiodevices such as bioelectronics and biochips to improve theirare the most widely used of the various other nanotechnologiesfor manipulation at the nanoscale as wel as nanobiosensors.The immobilization of biomolecules is playing an increasinglyimportant role in the development of biodevices with highperformance. Nanopatterning technology, which is able toincrease the density of chip arrays, offers several advantages,including cost lowering, simultaneous multicomponent detection,and the efficiency increase of biochemical reactions. Afluids is also one of the main applications of nanotechnologies.This can be widely utilized in the various fields because it canreduce detection time due to tiny amounts of fluids, increasesignal-to-noise ratio by nanoparticles in chanel, and detectmulti-targets simultaneously in one chamber. This article reviewsnanotechnologies such as the application of nanoparticles for thedetection of biomolecules, the immobilization of biomoleculesat nanoscale, nanopatterning technologies, and the microfluidicsystem for molecular diagnosis.
