Summary
Nitrogen plasma treatment enhanced the antibacterial properties of turmeric-dyed cotton fabrics. Silver nitrate mordant achieved 100% antibacterial activity, showing a synergistic effect with plasma.
Area of Science:
- Materials Science
- Textile Chemistry
- Biotechnology
Background:
- Cotton fabrics are widely used but lack inherent antibacterial properties.
- Natural dyes like turmeric offer potential antimicrobial benefits.
- Plasma treatment and mordants can enhance fabric functionality.
Purpose of the Study:
- To investigate the antibacterial efficacy of turmeric dye on cotton fabrics.
- To evaluate the impact of nitrogen plasma treatment on antibacterial activity.
- To assess the role of silver nitrate as a mordant in conjunction with plasma treatment.
Main Methods:
- Cotton fabric samples were treated with nitrogen plasma.
- Samples were dyed with turmeric, with some pre-treated with silver nitrate (AgNO3).
- Antibacterial activity was tested, alongside SEM and spectrophotometry analysis.
Main Results:
- Turmeric dye exhibited inherent antibacterial efficiency.
- Nitrogen plasma treatment significantly improved the antibacterial activity of turmeric-dyed fabrics.
- Silver nitrate mordant treatment resulted in 100% antibacterial activity.
- Nitrogen plasma showed a synergistic effect with turmeric dye for enhanced antibacterial properties.
Conclusions:
- Nitrogen plasma and silver nitrate are effective in imparting antibacterial properties to cotton fabrics.
- Turmeric, as a natural dye, combined with these treatments, offers a promising eco-friendly antimicrobial solution.
- The synergistic effect highlights the potential for advanced textile finishing techniques.

01:26Physical Methods for Controlling Microbial Growth: Radiation and Filtration
1.5K
Radiation and filtration are essential tools for microbial control, targeting microorganisms through distinct mechanisms. Radiation eliminates microbes by damaging their DNA, either killing them or inhibiting their growth. Based on wavelength, radiation is classified into two types: nonionizing and ionizing radiation.Non-ionizing radiation, such as UV radiation (200–400 nm), is absorbed by DNA, causing defects that effectively disinfect surfaces, air, and water, including safety cabinets.

Chemicals play important roles in controlling microbial growth by targeting microbial structures and functions as sanitizers, antiseptics, disinfectants, and sterilants.Alcohols are commonly used sanitizers, effectively disrupting lipid membranes, which compromises cell integrity. They are also used as antiseptics and disinfectants due to their rapid action and versatility.Phenols and their derivatives phenolics , known for denaturing proteins and disrupting cell membranes, are particularly...

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...

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements.
Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...

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.
