A study of an integrated OPECT biosensor gate and the EC color-changing region on the same chip was carried out, achieving sensitive detection through bioetching-induced signal changes. Enzymatic bioetching enables specific alkaline phosphatase (ALP) detection by catalyzing the production of CdS, which modulates the channel current and generates a visual signal.

The synergistic effect between surface metal vacancies and a Schottky junction on enhanced transconductance, and the gating effect of an organic photoelectrochemical transistor was reported. [ABSTRACT FROM AUTHOR]

A distance-based visual electrochromic biosensing device is proposed. With this device, the naked eye is capable of discerning the distance of discoloration, which exhibits a positive correlation with the concentration of the detected substance. [ABSTRACT FROM AUTHOR]

A novel strong solvent coordination leaching method was developed to prepare surface zinc vacancies in ZnO nanorod arrays. Remarkably, the surface-zinc-vacancy-rich ZnO nanorod arrays exhibit high electron – hole separation efficiency and excellent photoelectrochemical performance for use as a promising candidate for the next generation of organic photoelectrochemical transistor aptasensors.

We demonstrated that the activity gap between metal–organic frameworks (Fe) and horseradish peroxidase could be bridged by simulating the binding-pocket structure and adding active centers. This customized structure promoted the activation and enrichment of substrates, and addition of gold nanoparticles led to activity superposition and synergistic enhancement. [ABSTRACT FROM AUTHOR]
