What is it about?

Our research focuses on modifying the surface properties of PUMA & OSTE with nitrogen and argon gas plasma treatment. Both plasma treated substrates possess the necessary chemical and physical properties to be further developed as a potential biochip.

Why is it important?

Native PUMA & OSTE are not biocompatible. Thus, plasma treatments insert nitrogen groups which are more hospitable for endothelial cells grows on the OSTE and PUMA.


PUMA was developed in-house by IMEN, Universiti Kebangsaan Malaysia while OSTE was introduced by KTH, Royal Institute of Technology, Sweden. The biocompatibilities of both polymeric substrates improved after the single-step plasma treatments. Plasma treated PUMA & OSTE has the potential to replace the current industry work-horse, i.e., PDMS in the lab-on-chip fabrication.​
