Surface Membrane Barriers01:18

Surface Membrane Barriers

1.1K
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Hand hygiene

3.2K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Antimicrobial Proteins01:23

Antimicrobial Proteins

992
Antimicrobial proteins are important components of the immune system. They aid the body in combating pathogens by either killing them directly or hindering their replication processes. Four main types of antimicrobial substances are interferons, the complement system, iron-binding proteins, and antimicrobial proteins.
Interferons
Interferons (IFNs) are proteins produced by lymphocytes, macrophages, and fibroblasts infected with viruses. While IFNs cannot prevent viruses from entering and...

Area of Science:

  • Materials Science
  • Textile Engineering
  • Antimicrobial Technologies

Background:

  • High-performance aramid fibers are crucial in protective gear and industrial applications.
  • Bacterial proliferation on textiles is a significant issue, especially when frequent washing is not feasible.
  • Existing aramid materials lack inherent antimicrobial properties, limiting their use in certain environments.

Purpose of the Study:

  • To develop a scalable method for imparting bactericidal activity to aramid-coated textiles and films.
  • To evaluate the impact of vanillin functionalization on the mechanical and thermal properties of aramids.
  • To assess the antibacterial efficacy, reusability, and biocompatibility of the novel bactericidal aramid materials.

Main Methods:

  • Aramid-coated textiles and films were prepared by reacting parent aramids with vanillin.
  • Mechanical properties were evaluated using tensile tests to determine Young's modulus.
  • Thermal performance was assessed, and antibacterial activity was quantified using A parameters against Staphylococcus aureus and Klebsiella pneumoniae. Skin irritation tests were conducted using reconstructed human epidermis.

Main Results:

  • Vanillin functionalization preserved high-performance characteristics and enhanced mechanical properties, increasing Young's modulus by up to 50% compared to commercial m-aramid.
  • The bactericidal aramid materials demonstrated significant antibacterial activity with A parameters of 4.31 for S. aureus and 3.44 for K. pneumoniae.
  • The coated textiles maintained their performance over at least 5 washing cycles and were found to be non-irritating to the skin.

Conclusions:

  • A straightforward and scalable method for creating intrinsically bactericidal aramid materials has been established.
  • These functionalized aramids offer a combination of high performance, improved mechanical strength, and robust antibacterial properties.
  • The metal-free, non-irritating bactericidal aramids are suitable for applications requiring both durability and antimicrobial function, such as first responder textiles and filters.
