High quality fluorescent cellulose nanofibers from endemic rice husk: Isolation and characterization

- Isolation of high purity cellulose nanofibers (CNFs) from two rice husk varieties.
- Highly crystalline CNFs with small crystallite sizes (3.3-5.6 nm) isolated.
- Native fluorescence property of CNFs with high quantum yield (∼58%) exhibited.
- CNFs found to be thermostable and biocompatible.
