Chemical Agents for Microbial Control

Chemical Agents for Microbial Control

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...

Waterproofing and Anti-Bacterial Admixtures in Concrete

Waterproofing and Anti-Bacterial Admixtures in Concrete

Concrete's susceptibility to water absorption is due to the capillary action within the pores of its hydrated cement paste. This action draws water in, creating the need for waterproofing admixtures to prevent such penetration. The efficacy of these admixtures is contingent upon the water pressure, with variations arising from different conditions such as rain, capillary rise, or hydrostatic pressure in structures intended to hold water.
Waterproofing admixtures render concrete hydrophobic,...

Antimicrobial Proteins

Antimicrobial Proteins

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...

Methods of Sterilization II: Chemical Methods

Methods of Sterilization II: Chemical Methods

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,...

Antimicrobial Effectiveness

Antimicrobial Effectiveness

The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...

Surface Membrane Barriers

Surface Membrane Barriers

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...

Materials Science
Textile Chemistry
Antimicrobial Agents

Background:

Cotton fabrics are widely used but lack inherent antimicrobial properties.
Developing durable antimicrobial textiles is crucial for healthcare and consumer goods.
Traditional antimicrobial treatments can be harsh or disrupt manufacturing.

Purpose of the Study:

To develop a novel method for imparting antimicrobial properties to cotton fabrics.
To investigate the efficacy of organoselenium compounds as antimicrobial agents for textiles.
To assess the durability and compatibility of the treatment with existing textile processes.

Main Methods:

Cotton fabrics (bleached and cationized) were chemically modified using reactive organoselenium compounds via nucleophilic aromatic substitution (S_NAr).
Organoselenium attachment was achieved through covalent bonds and ionic interactions (for cationized cotton).
Antimicrobial efficacy was tested against *Staphylococcus aureus*, *Escherichia coli*, and *Candida albicans*.

Main Results:

Treated fabrics demonstrated potent bactericidal activity against *S. aureus* (99.99% reduction).
Moderate activity was observed against *E. coli*, and significant fungicidal activity against *C. albicans*.
Antifungal activity was higher on cationized cotton, and the antimicrobial effect was durable to washing.

Conclusions:

A novel, durable method for creating antimicrobial cotton fabrics using organoselenium compounds has been developed.
This approach offers effective bacterial and fungal resistance without disrupting industrial textile production.
The findings present a promising strategy for functionalizing textiles with antimicrobial properties.
