Polymer processing and surface modification by extreme ultraviolet (EUV) photons for application in biomedical engineering
Recent advancements in organic materials as “Green Alternatives” in various applications dramatically increased the requirement of efficient surface modification techniques, which would be able to tune the surface properties without altering mechanical properties of the bulk material. The thickness of such materials (e.g biosensors, bio-mimetic artificial implants, artificial muscles, organic electrodes for biomedical engineering applications, and many more) is limited to few millimeters. The conventional chemical, ultraviolet (UV) and plasma based techniques produce undesirable effects such as alteration of bulk material properties and lacks long term sustainability. Such problems limit their applicability in biomedical engineering applications.
Extreme ultraviolet (EUV) photons with energies from 30 eV up to 250 eV (corresponding to wavelengths in vacuum from 40 nm to 5 nm respectively) have limited penetration depths (up to 100 nm) in to the polymer surface. Therefore the modification of physical and chemical properties will be limited to upper layer surface and the bulk properties will remain intact.
In this project, surface modification of various polymers will be performed by EUV photons. The EUV irradiated samples will be characterized through SEM, AFM, XPS and water contact angle measurements. Cell culture studies will be performed to evaluate degree of biocompatibility in EUV modified polymers.
Mr. Inam Ul Ahad has graduated from Sir Syed University of Engineering and Technology in Biomedical Engineering, in 2007. He earned his M.Sc. degree in Biomedical Engineering from Furtwangen University of Applied Sciences, Germany in 2009. He worked as visiting researcher in Gambro Dialysatoren GmbH, Germany for his master thesis on modeling and simulation of mass transfer and fluid dynamics in dialyzers. In 2010, Mr. Ahad joined Sir Syed University of Engineering and Technology as faculty member in Biomedical Engineering department.
During this tenure, he was involved in various academic activities in B.S. and M.Sc. Biomedical Engineering programs. Mr. Ahad joined EXTATIC Erasmus Mundus Joint Doctorate program in September 2012. His project title is “Polymer processing and surface modification by extreme ultraviolet (EUV) photons for application in biomedical engineering”. He is particularly interested in development and demonstration of nanotechnology tools for biomedical engineering applications.
