Abstract
The present study investigated the development of biocompatible and micro-thin hybrid film by using alginate, α-tricalcium phosphate nano/micro-particle and calcium chloride through ionic crosslinking as a biomaterial for bone tissue engineering. Control of its diverse properties was developed by using micro-environments such as Screeding processing, pHs, compositions of the hybrid films. Physicochemical and biological properties of the films were evaluated by SEM, UV-VIS, NMR, swelling properties as well as drug delivery from the films. The hybrid films showed excellent biocompatibility as judged by in vitro bone cell tests at different pHs and cytotoxicity over time. Currently, applications of thin/flexible hybrid films to micro-fluidics and tissue engineering are under processing. Microfluidic tubing system has been fabricated by 3D bioprinting system and biodegradable polymers in our lab.
