“…They are used in microbiology to detect, correctly identify, and even quantify different types of bacteria. -(Photo)electrochemical biosensors (PEC) [174][175][176][177] use photoelectrical materials as electrodes. These are able to convert light into electrical current that, when processed, is used for the detection and quantification of biomolecules.…”

For many years, TiO2-based materials and improving their properties in order to expand their application areas have been the focus of numerous research groups. Various innovative approaches have been proposed to improve the photocatalytic and gas-sensing properties of TiO2 nanostructures. In this review, we aim to synthesize the available information in the literature, paying special attention to the sol–gel technology, which is one of the most frequently used methods for TiO2 synthesis. The influence of dopants on the structural, morphological, optical, and electrical properties of TiO2 and the way to modify them in a controlled manner are briefly discussed. The role of shallow and/or deep energy levels within the TiO2 bandgap in the electron transport behavior of doped TiO2 is emphasized. Selected research on photocatalytic applications in water disinfection, wastewater treatment, and self-sterilizing coatings that contribute to improving the quality of human life and environmental preservation is highlighted. A survey of biosensors that are closely related to medical applications such as cancer detection, implantology, and osteogenesis is also provided. Finally, the pressing problems that need to be solved in view of the future development of TiO2-based nanostructures are listed.

The α-Fe2O3 nanoparticles were prepared via the alcohol solution combustion process of ferric nitrate. The scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS). X-ray diffraction (XRD), and vibrating sample magnetometer (VSM) were taken to characterize the prepared α-Fe2O3 nanoparticles. The average particle sizes of the as-prepared α-Fe2O3 nanoparticles were approximately 180 nm, and their magnetic property was approximately 0.42 emu·g-1 after the measurement. The different concentrations of BSA solutions and the adsorption times were investigated to investigate the adsorption characteristics of bovine serum albumin (BSA) onto α-Fe2O3 nanoparticles. For larger adsorption capacity and higher removal rate, the dose of α-Fe2O3 nanoparticles in aqueous solution was selected at 2.5 mg·mL-1. The adsorption process of BSA onto α-Fe2O3 nanoparticles conformed to the pseudo-first-order kinetic model. While, the correlation coefficient (R2) of the Temkin isothermal model was higher than Langmuir model and Freundlich isothermal model, suggesting that the isothermal model of BSA onto α-Fe2O3 nanoparticles was more in line with Temkin isotherm model. Which suggested that the adsorption behavior of magnetic α-Fe2O3 nanoparticles for BSA belonged to multi-molecular layer chemisorption. When BSA concentration was 600 mg·L-1 and the pH of solution was 5, the adsorption capacity of BSA onto magnetic α-Fe2O3 nanoparticles achieved 114.2 mg·g-1, and the adsorption rate could still reach 70.3% of the first time after 7 cycles.
