A novel electrochemical detection method utilizing a cost-effective hybrid-modified electrode has been established. A glassy carbon (GC) modified electrode was tested for its ability to measure electrochemical tTG antibody levels, which are essential for diagnosing and monitoring Celiac disease (CD). Tissue transglutaminase protein biomolecules are immobilized on a quantum dots-polypyrrole nanocomposite in the improved electrode.

Article Synopsis
  • A new glassy carbon electrode was created using a combination of polypyrrole and carbon quantum dots to detect anti-tissue transglutaminase (anti-tTG) antibodies.
  • Four types of carbon nanoparticles were tested for improving the conductivity and performance of the polypyrrole-based electrode before it was functionalized with a dendrimer and protein through cross-linking methods.
  • The modified electrode showed excellent stability and sensitivity, allowing detection of low levels of anti-tTG antibodies (as low as 0.79 U/mL) without needing a secondary labeling process.

The aim of the present research is to develop a novel hybrid coating for a Ti dental implant that combines nature-inspired biomimetic polymers and TiO nanostructures with an entrapped ZnO antimicrobial agent. ZnO was used in other studies to cover the surface of Ti or Ti-Zr to reduce the need of clinical antibiotics, prevent the onset of peri-implantitis, and increase the success rate of oral clinical implantation. We developed an original coating that represents a promising approach in clinical dentistry.

This study presents the impact on human health by consuming medicinal herbs with high melliferous potential (HMPs) from botanical areas with different pollution levels. First, the bioaccumulation of the plants' parts has been determined. The study assessed the potential health risks associated with the ingestion of various mineral species (macroelements-K, Ca, Mg, Na; microelements-Fe, Mn, Cu, Zn, and one trace element Cd) from three types of HMPs ( (), (), and ()).
