Development and validation of matlab models for nanowire sensors

Abstract

In this paper, mathematical models required to describe the functionality of nanodevices are reviewed, and based on the mathematical models sensor equivalent circuit is developed. An experimental setup is developed to analyze the characteristics of ISFET, nanowire and nanosphere devices. Impact of geometrical properties on device performance is estimated based on the experimental setup. Settling time and surface analyte concentration graphs obtained using the experimental setup is used in designing a nanobio sensor (DNA) for disease detection. Based on the test results a mathematical model is develop in Matlab to model nanodevices. The DNA sensors modeled can be used for automated drug detection and delivery unit. © 2011 Springer-Verlag.
