Scientists have developed a new technique called solid-state NMR that can examine fungal cell walls without damaging them, revealing how these structures are built and reorganized. This research shows that different fungi have different wall architectures made of sugar-like molecules including chitin and various glucans, and that fungi can quickly adapt their walls when exposed to antifungal drugs. These findings could help develop better antifungal treatments by targeting the specific structural features that different fungi rely on for survival.
