Article Synopsis
- Hematite is a catalyst used in photoelectrochemical water-splitting cells, but understanding its interaction with water and the underlying mechanisms for oxygen production is limited.
- The study uses Fe-terminated hematite surfaces to propose a detailed mechanism for oxygen evolution, highlighting key reactive intermediates identified through advanced molecular dynamics simulations.
- The research suggests that how water interacts with these intermediates impacts the reaction process, and it notes that the desorption of oxygen is crucial since its adsorption can hinder further reactions by blocking active sites.

Background: In the process of food production, ciprofloxacin (CIP), a highly prescribed fluoroquinolone antibiotic, is often excessively used to reduce the risk of bacterial infection. However, this overuse can cause severe harm to human health, including allergic responses, gastrointestinal complications, and potential renal dysfunction. The development of a robust and precise detection method for CIP is crucial, given the interconnection between food security and human health.

The use of amorphous TiO (a-TiO), deposited by atomic layer deposition, is a common strategy to protect semiconductors from degradation when used in water-splitting photoelectrochemical (PEC) cells. Electrochemical impedance spectroscopy (EIS) is a suitable technique to study these PEC cells because it is capable of deconvoluting multiple processes occurring during operation, therefore providing information about mechanisms leading to the overall device performance. When biased under hydrogen evolution conditions, EIS shows that two simultaneous processes occur in a-TiO-protected photocathodes, which introduces an ambiguity in choosing the correct equivalent circuit to describe the operating device.

Immunoassays have been widely used for the determination of various analytes in the fields of disease diagnosis, food safety, and environmental monitoring. Dual-signal immunoassays are now advanced and integrated detection technologies with excellent self-correction and self-validation capabilities. In this work, we summarize the recent advances in the development of optical and electrochemical dual-signal immunoassays, including colorimetric, fluorescence, surface-enhanced Raman spectroscopy (SERS), electrochemical, electrochemiluminescence, and photoelectrochemical methods.
