Nanomaterials and analytical chemistry

Nanomaterials play an important role in the area of sensor technology. In fact the sensitivity and the signal-to-noise ratio of many chemical sensors are significantly improved using nanomaterials. They have allowed the introduction of many strategies in sensors and biosensor technology. Recently, catalytic nanomotors were used for drug delivery, showing an oriented motion into the cells when they are assembled using magnetic nanowires. In this review, detailed bibliographic references are presented concerning the assembling of nanomaterial-based sensors, and a brief discussion about the potential health risk of nanoparticles will be also presented.
