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...

Microbial Corrosion

Microbial Corrosion

Microbiologically Influenced Corrosion (MIC) is a significant form of material degradation caused by the metabolic activities of microorganisms. This phenomenon poses substantial challenges across various industries, including oil and gas, maritime, and water treatment sectors.MIC occurs when microorganisms, such as bacteria, archaea, and fungi, colonize metal surfaces, forming biofilms that alter the local electrochemical environment. These biofilms can lead to the production of corrosive...

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...

Production of Antibiotics

Production of Antibiotics

Penicillin, one of the earliest and most widely used antibiotics, is produced industrially by the filamentous fungus Penicillium chrysogenum. Large stirred-tank bioreactors ranging from tens to hundreds of thousands of liters maintain tightly controlled temperature, pH, and dissolved oxygen conditions to support fungal metabolism and maximize antibiotic yield. Penicillin is a secondary metabolite, synthesized primarily during the stationary growth phase, which requires a carefully managed...

Treating Helicobacter pylori in Peptic Ulcers: Antimicrobial Therapy

Treating Helicobacter pylori in Peptic Ulcers: Antimicrobial Therapy

Helicobacter pylori, a resilient gram-negative bacterium, can thrive in the stomach's harsh, acidic environment. Infection with H. pylori leads to a cascade of events within the stomach lining. One of the critical disruptions caused by this bacterium is the interference with somatostatin production, a hormone responsible for regulating acid secretion. This interference tips the balance, escalating acid secretion and diminishing bicarbonate levels. This imbalance compromises the defensive...

Area of Science:

Materials Science
Textile Chemistry
Nanotechnology

Background:

Cotton fabrics require advanced finishing treatments to impart desirable properties like antimicrobial activity and improved physical performance.
Core-shell nanoparticles offer unique functionalities for textile applications due to their distinct core and shell components.

Purpose of the Study:

To develop a multifinishing treatment for cotton fabrics using silver core-shell nanoparticles.
To evaluate the antibacterial efficacy and physical property enhancements of the treated cotton fabrics.
To optimize the treatment parameters, including nanoparticle concentration, citric acid levels, and curing conditions.

Main Methods:

Synthesis of silver (Ag(0)) core and chitosan-O-methoxy polyethylene glycol (CTS-O-MPEG) shell nanoparticles.
Application of the synthesized nanoparticles onto cotton fabrics via the pad-dry-cure method.
Characterization of nanoparticle dispersion using Scanning Electron Microscopy with Energy Dispersive X-ray spectroscopy (SEM-EDX).

Main Results:

Well-dispersed core-shell nanoparticles were observed on the cotton fabric surface.
Optimized treatment (1% nanoparticles, 5% citric acid, 80°C drying, 160°C curing for 2 min) yielded excellent antibacterial activity against Escherichia coli and Staphylococcus aureus.
Treated fabrics maintained significant antibacterial efficacy even after 20 washing cycles.
Enhancements in crease recovery angles (CRA) and a slight improvement in tensile strength (TS) were noted.

Conclusions:

The developed Ag(0)-CTS-O-MPEG core-shell nanoparticle treatment provides durable antibacterial properties to cotton fabrics.
The treatment also improves the physical performance of cotton textiles, specifically crease recovery and tensile strength.
This nanotechnology-based approach offers a promising solution for advanced textile finishing with multifunctional benefits.
