Summary
Surface-active ionic liquids (SAILs) with longer alkyl chains exhibit enhanced antimicrobial properties due to increased hydrophobicity. Their micellization, antimicrobial action, and cytotoxicity were investigated using experimental and theoretical methods.
Area of Science:
- Materials Science
- Physical Chemistry
- Biochemistry
Background:
- Surface-active ionic liquids (SAILs) are versatile compounds with tunable properties.
- Understanding the relationship between SAIL structure and function is crucial for their application.
- Imidazolium-based SAILs are of particular interest due to their unique characteristics.
Purpose of the Study:
- To investigate the influence of alkyl chain length and counter-ion type on SAIL properties.
- To examine the micellization behavior, antimicrobial activity, and cytotoxicity of various SAILs.
- To correlate experimental findings with theoretical calculations for structural insights.
Main Methods:
- Tensiometry and steady-state fluorescence spectrophotometry for micellization studies.
- Gaussian software for theoretical geometric optimization of SAIL structures.
- Antimicrobial screening against bacteria and fungi, and cytotoxicity assessment on HeLa cells using MTT assay.
Main Results:
- SAILs with alkyl chains longer than C8 demonstrated effective antimicrobial activity, linked to increased hydrophobicity.
- Micellization parameters (CMC, Гmax, Amin) were evaluated and correlated with hydrophobicity.
- Theoretical simulations provided insights into the structural aspects influencing micellization.
Conclusions:
- Hydrophobicity is a key factor driving the antimicrobial efficacy of SAILs.
- SAILs with longer alkyl chains show promise as antimicrobial agents.
- Combined experimental and theoretical approaches enhance understanding of SAIL behavior and potential applications.

760
Interfacial electrochemical methods focus on the phenomena occurring at the boundary between an electrode and a solution, as opposed to bulk methods that concentrate on the solution's overall properties. These interfacial methods are classified as either static or dynamic based on the presence of a nonzero current in the electrochemical cell and the consistency of analyte concentrations. Static methods, such as potentiometry, measure the cell's potential without any significant current...

2.5K
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...
