Summary
Comparing antifungal testing methods for textiles, this study found colony counting depends on fungal form, while luminescence does not. Accurate evaluation requires understanding each method
Area of Science:
- Textile science
- Mycology
- Analytical chemistry
Background:
- Textile materials are increasingly modified for antimicrobial properties.
- Quantitative assessment of antifungal activity is crucial for product development.
- Standardized testing methods are needed for reliable efficacy evaluation.
Purpose of the Study:
- To compare quantitative antifungal testing methods for textile fabrics.
- To investigate fungal growth on unmodified and silver nanoparticle-modified textiles.
- To evaluate the influence of fungal morphology on test results.
Main Methods:
- Colony counting method for fungal enumeration.
- Luminescence-based method for assessing metabolic activity.
- Microscopic observation for fungal morphology.
- Testing on unfinished and Ag nanoparticle-treated textile fabrics under growth-supportive conditions.
Main Results:
- Colony counting results were influenced by the morphological state of fungi on fabrics.
- Luminescence method results were independent of fungal morphology.
- Silver nanoparticle modification showed varying antifungal effects depending on the testing method.
Conclusions:
- The choice of antifungal testing method significantly impacts the evaluation of textile efficacy.
- Method-specific characteristics, such as sensitivity to fungal morphology, must be considered.
- Selecting appropriate quantitative methods is essential for accurate antifungal performance assessment of textiles.
