Biodegradable cellulose nanocrystal composites doped with carbon dots for packaging and anticounterfeiting applications

-based films have exhibited effective control over microbial load due to nitrogen doping. These films biodegrade within 29 days when buried in soil after use. This innovative approach presents multifunctional films that address critical needs in sensing, anti-counterfeiting, and intelligent packaging and opens new avenues for creating eco-friendly, multifunctional materials.
