N2 - This work evaluates the photostability of non-doped carbon-based nanomaterials (CBNs) in aqueous dispersion and hydrogel matrices. Fluorescence was monitored under five storage conditions, revealing that unencapsulated CBNs were prone to degradation when exposed to light and oxygen. In contrast, encapsulation in hydrogel significantly improved stability. Hydration and rehydration tests confirmed that hydrogel matrices retained fluorescence and enhanced reproducibility, supporting their potential for developing stable sensing platforms.
