Ferric ions show high affinity to the kinase-generated phosphorylated sites of peptides. Thus, the high electrocatalytic activity of the coordinated ferric ions toward the reduction of hydrogen peroxide can be used for sensitive label-free monitoring of protein kinase activity and inhibition.

This research presents a simple procedure for chemically modifying yeast () cells with nickel hexacyanoferrate (NiHCF) and ferric hexacyanoferrate, also known as Prussian blue (PB), to increase the conductivity of the yeast cell wall. Using linear sweep voltammetry, NiHCF-modified yeast and PB-modified yeast (NiHCF/yeast and PB/yeast, respectively) were found to have better cell wall conductivity in [Fe(CN)] and glucose-containing phosphate-buffered solution than unmodified yeast. Spectrophotometric analysis showed that the modification of yeast cells with NiHCF had a less harmful effect on yeast cell viability than the modification of yeast cells with PB.

The detection of biomarkers is crucial for assessing disease status and progression. Uric acid (UA), a common biomarker in body fluids, plays an important role in the diagnosis and monitoring of conditions such as hyperuricemia, chronic kidney disease, and cardiovascular disease. However, the low concentration of UA in non-invasive body fluids, combined with numerous interfering substances, makes its detection challenging.

The aim of this study is to investigate the effect of the adhesive, conductive hydrogel on wound healing when used as a therapeutic dressing. Herein, a dressing of PVA/QCS/TP@Fe (PQTF) was designed and prepared integrating polyvinyl alcohol (PVA), chitosan quaternary ammonium salt (QCS), tea polyphenol (TP), and ferric ions (Fe) by a simple one-pot and freeze-thaw method. In view of the comprehensive properties of PQTF hydrogel, including adhesion, electrical conductivity, and swelling performance, PQTF was selected for subsequent in vitro and in vivo healing promotion studies.
