Synthesis of uniformly dispersed FeTiO nanodisks: a sensitive photoelectrochemical sensor for glucose monitoring in human blood serum.

A novel photoelectrochemical (PEC) sensor was constructed, using FeTiO nanodisks under visible-light irradiation, for the determination of glucose in human blood serum. The uniformly dispersed FeTiO nanodisks were synthesized for the first time by an ion exchange method and subsequent heat treatment. As excellent catalysts, the FeTiO nanodisks can directly catalyze the oxidation of glucose to produce current in the absence of glucose oxidase.

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which emerged as a novel pathogen in 2019. The virus is responsible for a severe acute respiratory syndrome outbreak, affecting the respiratory system of infected individuals. COVID-19 is a super amplifier of basic diseases, and the disease with basic diseases is often more serious.
