Special Issue Information

Dear Colleagues,

Surface engineering studies, as well as surface chemical reactions, can be studied in various types of complex systems due to technological advances in materials characterization methods. Surface modification can be performed by exposure to ‘plasma’, which are ionized gaseous molecules that generate a glow discharge upon supply of electric field due to their excitation into energetic states. Studies suggest that since plasma is limited to a few tens of nanometers, the bulk properties of the surface remain intact. This is crucial for clinical applications, as further FDA approval would not be required. Additionally, plasma surface modification is a reliable, reproducible, and relatively inexpensive technique applicable to implants made from metals, polymers, textiles, ceramics, and composites providing a surface ‘coating’. This Special Issue welcomes contributions on ‘Plasma Surface Modification for Bio-Applications’, with the aim to highlight the current state-of-art of research in this area. The Special Issue will accept diverse forms of contributions, for example, papers focusing on the interface/surface engineering for nanotechnology, biomedical, agricultural, and other applications.

In particular, the topic of interest includes but is not limited to

  • Plasma;
  • Surface Modification;
  • Analytical Chemistry;
  • Bio/nano-materials;
  • Applications

Medical devices are often vulnerable to colonization by nosocomial pathogens (bacteria), leading to infections. Traditional sterilization methods may not always be effective, and as a result, alternative options are being explored to prevent microbial contamination. Recently, scientists are emphasizing using plant-derived essential oils that possess inherent antibacterial properties to produce antimicrobial coatings using plasma polymerization technology carried out at atmospheric pressure (AP). This approach shows promise compared to other coating strategies that need several processing steps, including a high-vacuum system, and are laborious, such as the immobilization of antimicrobial materials on precoated layers in the low-pressure plasma polymerization approach. The present study demonstrates the potential of AP plasma polymerization for producing thin films with excellent antibacterial properties and surface characteristics. The resulting coatings are stable, smooth, and have high wettability, making them ideal for repelling bacteria. The calculated zeta potential and deposition rate for the films are also favorable. These AP plasma-polymerized thin films created from carvone show a reduction rate of more than 90% for Escherichia coli and Staphylococcus aureus bacteria. Our computational docking studies also reveal strong binding interactions between the original carvone monomer and both bacteria. The study suggests that these AP plasma-produced coatings have great potential as antibacterial coatings for biomedical devices. Full article
