Synthetic wood composite beads containing cellulose, hemicelluloses, and lignin, the three major components of natural wood, were prepared in a room temperature ionic liquid, 1-ethyl-3-methylimidazolium acetate, [Emim][Ac]. Protein-entrapped synthetic wood composites were obtained by dissolution of individual wood components together with proteins, including green fluorescent protein (GFP), red fluorescent protein (RFP), and lipase, in [Emim][Ac] followed by reconstitution with distilled water. GFP and RFP-entrapped composite beads exhibited their characteristic colors under blue and green light irradiation, respectively. Synthetic wood beads containing lipase showed higher protein loading and operational stability, compared with lipase-entrapped cellulose beads.1 Various characteristics of synthetic wood composite beads such as bead size, hydrophobicity, surface morphology, and swelling ability can be easily controlled by changing the ratio of three major components.2,3
