Abstract

Growing cells on microcarriers may have overcome the limitation of conventional cell culture system. However, the main challenge remains at ensuring the surface biocompatibility with cells. Polycaprolactone (PCL), a biodegradable polymer, has received considerable attention because of its excellent mechanical properties and degradation kinetics that suit various applications, but its non-polar hydrocarbon moiety renders it sub-optimal for cell attachment. In this present study, oxygen functional group was introduced via ultraviolet irradiation and ozone aeration (UV/O3) system to allow covalent immobilization of gelatin on the PCL microcarrier surface using zero-length crosslinker reagent 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride and N-hydroxysuccinimide (EDAC/NHS). The optimum conditions for maximizing the amount of gelatin on the surface of PCL were as follows: 1.5 of COOH:EDAC ratio, 10mM NHS concentration and, 80 mg/ml gelatin.
