Another way of using cellulose beads is to place a magnetic particle
inside the structure and thus the new material could react as a
magnetic actuator. Moreover, the synthesis of the magnetic
cellulose [25] or polysaccharide like carboxymethyl-cellulose
[26] and carrageenan [27] has generated a great attention in
recent years due to their specific properties: non-toxic nature,
biocompatibility, variable ionic permeability, combined with a
high hydrophilicity and considerable mechanical strength.
