Advances in cellulose-based self-powered ammonia sensors.

Ammonia sensors are widely used across applications in food monitoring, environmental surveillance, and medical research, where high safety standards are essential. Cellulose-based materials are particularly well-suited to meet these stringent requirements, with significant potential for innovation due to their biodegradability and biocompatibility. Of the various cellulose-based ammonia sensors available, self-powered sensors, especially those based on triboelectric nanogenerators (TENGs), stand out for their unique advantages, including the absence of an external power supply, environmental sustainability, and ease of integration.

Development of cellulose-based self-healing hydrogel smart packaging for fish preservation and freshness indication.

Biomass-based composite packaging materials loaded with functional fillers have good application prospects in food preservation and freshness detection. Self-healing hydrogel packaging films based on nanocellulose (CNF), polyvinyl alcohol (PVA), and ZIF-8 embedded with curcumin (Cur@ZIF-8) were developed in this study. The synthesis of Cur@ZIF-8 was demonstrated by characterization experiments.

Advances in the enhancement of mechanical and hydrophobic properties of nanocellulose-based packaging materials: A review.

As environmental issues are hotly debated worldwide, finding suitable materials to replace petroleum-based materials as the next-generation packaging materials has become a research hotspot. Nanocellulose, as a biomass material widely available in nature, is favored for application in green packaging materials due to its environmentally friendly and bio-friendly characteristics. However, the unstable mechanical properties and strong hydrophilicity of nanocellulose limit its practical application in packaging materials.
