Cellulose beads have attracted great attention of scientists due
to their abundance, biodegradability, renewability, and low cost.
Cellulose beads can be chemically modified to serve as potential
biomedical engineering materials [4,5], and are being widely used
as the stationary phase in chromatography systems for separation
due to their spherical shape which allow easy packing in column
and withstand very high flow rates [6]. Besides, cellulose beads
have been chemically modified with different types of anionic
groups for use as the absorbent material in water treatment, such
as the removal of heavy metals in water resources [7]. The drug
loading capacity and release kinetics of cellulose beads have also
been studied for pharmaceutical and biomedical applications [8
