Due to the harmful effects of some biological and environmental hazard, many studies were directed to investigate advanced devices with high sensitive and fast detection. Biosensor is a device by which a readable information was produced at interaction of biological molecule with an electronic ingredient and has been highly developed to be used in a variety of applications using different bioreceptor, using transducers with different detection mechanisms and the most attractive use of nanomaterials in improving the performance of nanobiosensors. Nanomaterials have attracts great interest in improving and manufacture of biosensors. Where, the marked surface area of the nanosize particles enhances the immobilization of various biological molecules on its surface. These functionalized nanomaterials improve the detection and the strength of different signals. Moreover, this review discusses some types of biosensors that used in different biological and environmental applications and the effect of the nanomaterials on the enhancement of their performance.
