Summary: TiO2-decorated magnetic biochar was used for the photocatalytic degradation of tetracycline antibiotic, showing highest removal efficiency at neutral pH and a dosage of 0.35 g L-1. However, an increase in initial tetracycline concentration led to a decrease in removal efficiency. The process could effectively remove antibiotics from aqueous solutions while forming intermediate products with lower toxicity to the environment.

Summary: In this study, tetracycline hydrochloride (TCH) was encapsulated in carboxymethyl chitosan (CMCS) microcapsules (MCs). CMCS was synthesized to improve its pH sensitivity. The MCs were prepared and characterized using various techniques. The drug release behavior of TCH-loaded MCs was studied in different pH buffer solutions. The MCs/TCH showed promising antibacterial effects and could be used as drug delivery systems, especially in wound dressing applications.

Summary: The antimicrobial effect of chitosan and its derivatives has been confirmed on various bacteria and fungi. The tests conducted on pathogenic microorganisms revealed the inhibitory effect mechanism and concentration dependence of chitosan. By adding commercially available chitosan derivatives to a probiotic strain, it was determined that chitosan has a viabilty decreasing effect at concentrations above the minimum inhibitory concentration (MIC). The study also identified increased cell membrane permeability and irreversible interaction between low molecular weight chitosan and bacterial cells.

Summary: In this study, tetracycline hydrochloride (TC) was assembled with ferric ion and polyvinylpyrrolidone (PVP) into TC multifunctional nanoparticles (TCFNPs) to improve stability and antibacterial ability. Optimized conditions resulted in TCFNPs with a size of 9.95 nm and high storage stability. Additionally, TCFNPs exhibited photothermal effects that synergistically enhanced antibacterial performance. This study provides a new approach to enhance the stability and antibacterial ability of traditional antibiotics for agriculture.

Summary: The overuse or abuse of antibacterial drugs has resulted in serious health issues. Among various antimicrobial materials, especially ZnO, inorganic antimicrobial materials have gained wide attention. However, agglomeration is an important factor that affects the function of nanoparticles and compromises the antibacterial properties of ZnO. This study utilizes talc as a substrate to control the size and dispersion of ZnO, creating composite minerals with excellent antibacterial properties against Escherichia coli and Staphylococcus aureus.

Summary: In this work, a method for fabricating rutile-TiO2 films with different submicron thicknesses on SiO2 was proposed. The correlation between the generation of a positively charged TiO2 surface and E. coli attraction was investigated. Results showed that the formation of a positively charged TiO2 surface enhanced the photocatalytic antibacterial activity, facilitating the adsorption and degradation of negatively charged substances and pathogenic microorganisms.

Summary: Titanium dioxide (TiO2) nanoparticles interact with organic-inorganic pollutants in the environment, affecting their behavior. The study found that the adsorption of Cd2+ and tetracycline (TC) decreased in the presence of TiO2 nanoparticles. The competitive interactions between Cd2+ and TiO2, as well as TC and TiO2, led to reduced adsorption. TiO2 increased the mobility of pollutants on clay surfaces, particularly for organic pollutant TC.

Summary: API-ILs can increase the solubility and bioavailability of drugs without changing the drug molecule structure, overcoming the defects of solid drugs. In this study, tetracycline was used as the active drug and ethanoic acid and salicylic acid were selected as the anion to prepare tetracycline ionic liquids ([Tet][Gly] and [Tet][Sa]). The physical properties of [Tet][Gly] and [Tet][Sa], such as crystallinity, thermal stability, and solubility, were investigated. Tetracycline-resistant Escherichia coli was selected as a bacterial model to study the changes in bioavailability of tetracycline ionic liquids.
