The latest trend in nano-bio sensor signal analysis
Abstract
Purpose
This paper aims to discuss a nanoscale biosensor and its signal analysis algorithms.
Design/methodology/approach
In this work, five nanoscale biosensors are reviewed, namely, silicon nanowire field-effect-transistor biosensors, polysilicon nanogap capacitive biosensors, nanotube amperometric biosensors, gold nanoparticle-based electrochemical biosensors and quantum dot-based electrochemical biosensors.
Findings
Each biosensor produces a different output signal depending on its electrical characteristics. Five signal analysers are studied, with most of the existing signal analyser analyses based on the amplitude of the signal. Based on the analysis, auto-threshold peak detection is proposed for further work.
Originality/value
Suitability of the signal processing algorithm to be applied to nano-biosensors was reported.
