Biodegradable poly(lactic acid) scaffold for tissue engineering: a brief review
Revati, R1, Abdul Majid, M. S2, M. Normahira3.
Biodegradable polymers have been recorganized as alternative materials for tissue engineering
applications, due to their ability to degrade through simple hydrolysis to products which can be
accomplished through enzymatic activities in human body. Among various biomaterials used in
the synthesis of biodegradable polymer scaffold, poly(lactic acid) (PLA) has recently received
significant attention among researchers. PLA is at present one of the most preferred
biodegradable polymers for this purpose and has convincingly demonstrated the proof of concept
as biodegradable materials used in polymeric scaffold. This is due to their mechanical properties
and biological properties such as biocompatibility and biodegradability. Most importantly
incorporation of PLA with natural polymers such as gelatin and collagen enhanced the
mechanical properties with controllable degradation time. In particular, PLA has been
extensively studied for the development of scaffold for tissues such as bone tissue, drug delivery,
stent and artificial organ in commercial use and in research. In this review paper, an overview of
the scaffold design requirement and the effect of fabrication techniques on the pore size and
physical properties were discussed in detailed.
