An in-depth review on nanosensor technology and signal conditioning models among Nano sensors is discussed in this paper. First, the state of the art in nanosensor technology is surveyed from the device perspective, by explaining the details of the architecture and components of individual
nanosensors, as well as the existing manufacturing and integration techniques for nanosensor devices. Secondly, some of the signal conditioning methods with respect to modulation schemes is reviewed here. These discussion may leads to usage of the Nano-sensor in various application and especially
in medical application which is very much essential now-a-days. The signals can also be acquired, conditioned, processed and analyzed using Data Acquisition Card (DAC). Further, based on this information or data, medical supervisor can subscribe the required specific suggestions or treatment
to the people who are in need in this society.
