Paragraph starter

The research by Latko‐Durałek et al. (2023) demonstrates that incorporating silver and metal oxide nanoparticles into Polyamide 12 can achieve significant antifungal activity (up to 86% reduction). However, this enhancement may come at the cost of slightly reduced thermal stability and mechanical properties, particularly due to nanoparticle dispersion issues. This highlights the need for careful material selection and processing optimization when designing for antimicrobial functions.
