Enhanced response and selective gold nanoparticles/carbon nanotubes biosensor for the early detection of HER2 biomarker
A screen-printed carbon electrode was used to develop a biosensor with an improved response and selectivity for detecting human epidermal growth factor receptor 2 (HER2). To investigate the performance of the biosensor, electrochemical characterizations such as impedance spectroscopy, differential pulse and cyclic voltammetry were used, in addition to Fourier transform infrared spectroscopy and atomic force microscopy. The biosensor responds in a quick manner, taking only 5 min to bind to the target protein. Furthermore, the results show that the nano-biosensor has a detection limit of 4.4 Pg/ml. The findings suggest that the biosensor can be used as a potential analytical tool for HER2 detection, particularly at low concentrations, which can be a tool used in the early detection of breast cancer.
期刊介绍：
Sensors and Actuators Reports is a peer-reviewed open access journal launched out from the Sensors and Actuators journal family. Sensors and Actuators Reports is dedicated to publishing new and original works in the field of all type of sensors and actuators, including bio-, chemical-, physical-, and nano- sensors and actuators, which demonstrates significant progress beyond the current state of the art. The journal regularly publishes original research papers, reviews, and short communications.
For research papers and short communications, the journal aims to publish the new and original work supported by experimental results and as such purely theoretical works are not accepted.
