Extensive work on hybridization of nanocellulose and silver nanoparticles had impose a significant contribution to the demand for public health, environmental and biological protections. However, development from sustainable sources of nanocellulose and greener synthesis routes poses an impact to address the primary issues. This study exploited nanocrystalline cellulose (NCC) isolated from oil palm empty fruit bunches as a sustainable matrix for silver (Ag) nanoparticle synthesis via glucose as a green reduction agent. The absorption peaks from ultraviolet-visible (UV-Vis) analysis were centered around 410–430 nm, which validated the reduction of Ag ions to Ag nanoparticles within 3 min of synthesis duration. Morphological images showed that Ag nanoparticles were intermolecularly attached to the NCC matrix with particle sizes of between 33.6 and 62.3 nm. The antibacterial testing on S. aureus and E. coli confirmed the ability of Ag-NCC nanocomposite to act as an antibacterial agent with inhibition zone between 12 to 20 mm. In conclusion, the sustainable Ag-NCC nanocomposite synthesized via glucose as a sole reduction agent offered great potential for biomedical and food-related applications.
