Improper disposal of traditional plastics leads to the generation of microplastics, resulting in severe pollution of land and oceans and posing a threat to human health and marine ecosystems. Hence, adopting eco-friendly bioplastics, particularly in food packaging, is essential. In this study, Enset starch-based biocomposite films, reinforced with Ethiopian bentonite clay at various ratios (0, 2.

The incorporation of potato starch was successfully confirmed through XRD, FT-IR, and SEM analysis, while TGA highlighted the hydrogel's thermal stability. Batch adsorption experiments demonstrated excellent MB removal efficiency, with a maximum adsorption capacity of 116.

- - The study investigates how different types of lignin in biomass-derived carbon nanodots (CNDs) influence the formation of specific metal oxide phases and their efficiency in detecting dopamine electrochemically.
- - Findings indicate that syringyl-rich CNDs enhance the formation of a particular metal oxide phase (α-FeOOH/α-FeO@C) which offers better electrochemical performance and selectivity for dopamine detection compared to guaiacyl-rich CNDs.
- - The developed nanocomposites demonstrate rapid detection capabilities, high reproducibility, and stability, effectively working for real-time measurements of dopamine in human urine, showcasing their potential in biosensing applications.
