Based on the inherent gain amplification ability of field-effect transistors (FETs), weak biological signals can be amplified. The present study unveils a pH sensor based on a carbon nanotube (CNT)-FET, which exhibits remarkable environmental stability. Moreover, we have successfully validated the feasibility of utilizing this CNT FET device for pH sensing, showcasing a remarkable sensitivity of Vth at 82 mV pH−1 and 87 mV pH−1 for pH ranges of 1–7 and 7–13, respectively, an extensive pH range spanning from 1 to 13, as well as minimal hysteresis measuring at 0.726 mA with pH switching loops ranging from 4.85–9.12. This research not only realizes high-performance pH sensors, but also lays the foundation for the development of FET biosensors with excellent environmental stability. This is essential to ensure that FET biosensors function properly in complex systems.

New Journal of Chemistry

NJC (New Journal of Chemistry) is a broad-based primary journal encompassing all branches of chemistry and its sub-disciplines. It contains full research articles, communications, perspectives and focus articles. This well-established journal, owned by the Centre National de la Recherche Scientifique (CNRS) of France, has been co-published with the Royal Society of Chemistry since January 1998. NJC is the forum for the publication of high-quality, original and significant work that opens new directions in chemistry or other scientific disciplines. In addition to having a significant chemical component, work published in NJC must demonstrate that it will have an impact on areas of research other than that of the reported work.
