Physical Methods for Controlling Microbial Growth: Radiation and Filtration01:26

Physical 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.

Chemical Agents for Microbial Control

1.4K
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...

Surface Membrane Barriers

3.3K
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, Sterilization, and Disinfection

12.8K
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...

Methods of Sterilization II: Chemical Methods

10.4K
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,...

Hand hygiene01:23

Hand hygiene

6.4K
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.

  • 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.
