A simple and rapid immunochemical procedure is developed for estimation of the LDH1 activity which involved separation of LDH1 from other LDH isoenzymes using immunosorbent. The immunosorbent consisted of killed Staphylococcus aureus cells, membrane of which contained protein A with absorbed antibodies towards M-subunits of porcine LDH.

A colloidal gold immunochromatographic assay (ICA) based on a dual-antibody sandwich method was developed for the rapid and convenient detection of () antigens in the early stages of infection. Monoclonal antibodies designed as 5B3 targeting the conserved region of 56 kDa outer membrane protein in various strains of were generated through cell fusion and screening techniques and combined with previously prepared polyclonal antibodies as detection antibodies to establish the ICA. Colloidal gold and polyclonal antibody-colloidal gold complexes were synthesized under optimized conditions.

The main objective of this study is to prepare sodium alginate (SA)-based biofilms incorporated with watercress oil (WCO) as an antimicrobial material for sustainable food packaging. The physicochemical, antioxidant, and antibacterial properties of the prepared bio-based films were investigated. The antioxidant activity showed a remarkable increase, with DPPH inhibition increasing from 13.

This study introduces a novel approach to enhance the antibacterial properties of UIO-66 by incorporating both Thymol and ZnO nanoparticles within its framework which represents a significant advancement like exhibiting a synergistic antibacterial effect, providing a prolonged and controlled release, and mitigating cytotoxicity associated with the release of free ZnO nanoparticles by combining these two antimicrobial agents within a single, well-defined metal-organic framework. UIO-66 frameworks are investigated as carriers for the natural antimicrobial agent, Thymol, and ZnONPs offering a novel drug delivery system for antibacterial applications. Results demonstrated 132, 90, 184, and 223 nm sizes for UIO-66, ZnONPs, UIO-66 encapsulated Thymol, and UIO-66 encapsulated both Thymol and ZnONPs, respectively.

Rib fracture-related infection is a challenging complication of thoracic trauma due to the difficulty of treating it with antibiotics alone and the need for a second operation to remove the infected fixator and sterilize the surrounding infected tissue. In this study, inspired by the photocatalytic performance of and ion release from silver-based materials, including AgPO and AgS, a hybrid AgPO-AgS heterojunction was prepared based on anion exchange and a one-step calcination process to design a nonantibiotic coating aimed at preventing and treating rib fracture-related infection with short-term 808 nm near-infrared irradiation. Calcination at 250 °C enhanced the inductive effect of the phosphate radical and led to the formation of a tight nanoheterogeneous interface between AgPO and AgS, thereby promoting interfacial electron transfer and reducing the recombination of photogenerated carriers.
