We present fabrication methods of functional three-dimensional (3-D) micromesh structures coated with titanium dioxide (TiO2) microparticles and biocatalysts. The 3-D micromesh structures are useful for fabricating highly efficient microreactors because of their large surface area. In this study, TiO2-embedded SU-8 micromesh structures were formed by coating a TiO2/SU-8 mixture onto the surface of SU-8 micromesh structures. Biocatalyst- immobilized micromesh structures were also formed by coating a biocatalyst/photopolymer mixture onto SU-8 micromesh structures.
