The main difference between nano-object cellulose (10–100 µm) and nanostructured cellulose (1–50 nm) is the size of the

• recommended that nanocellulose be categorized into two main groups: CNC and CNF [20]. Overall, there are no fixed definitions for each group, since many nanocellulose sources coexist in the extensive and overlapping material space [29].

• cellulose pulp is required to produce CNF/CNC. In general, most CNCs and CNFs are produced through breaking down the cellulose fibres into nanosize fragments (top-down process), except for BC and electrospun cellulose nanofiber (ECNF) which utilize bacteria and an electrospinning technique (bottom-up
