Metal oxides based electrochemical pH sensors: Current progress and future perspectives

TL;DR: The relationship between the electrode structure and performance was investigated and discussed in this article , where the as-prepared iridium/iridium oxide electrodes were treated at 35 MPa and 400 °C for 3 h.

TL;DR: The motif of this review is to provide insight into trending tech-based systems employed in real-time or in-vivo pH-responsive monitoring, and prospective integration of various pH in vivo platforms with modern electronics that can open new avenues of cutting-edge techniques for disease diagnostics and prevention.

TL;DR: In this paper , the authors proposed to renew the antimony-based sensor by physical polishing and electrochemical cathode reduction, which improved the pH response sensitivity from 0.034 V/pH to 0.042 V/PH.

TL;DR: The development of an ion-sensitive solid-state device that combines the principles of an MOS transistor and a glass electrode and can be used for measurements of ion activities in electrochemical and biological environments is described.

TL;DR: In this paper, the development of ISFETs in an historical setting, but not limited to that, is described, based on the development regarding the theory, the technology, the instrumentation and the experience with many specific applications, also future projects are defined, such as concerning cell acidification, this paperET biasing and a complete new range of FET sensors based on local pressure induction by (bio)chemical interaction with immobilised charged molecules (hydrogels).

TL;DR: G graphene doped with gold and combined with a gold mesh has improved electrochemical activity over bare graphene, sufficient to form a wearable patch for sweat-based diabetes monitoring and feedback therapy and can be thermally actuated to deliver Metformin and reduce blood glucose levels in diabetic mice.

TL;DR: In this paper, the fundamental processes of diffusion and faradaic reaction at electrodes are discussed and a review of the applications of these processes can be found in a forthcoming volume in this series.
