title: Nondestructive analysis of dielectric properties: application to ion beam irradiated tissue response microfibre.
abstract: The aim of this work was to investigate the effect of 2.4 MeV proton irradiation on the dielectric property of polyethylene terephthalate (PET) microfibre nondestructively. The dielectric constant εd of single-microfibre has been measured as-such applying laser diffraction technique. Applying this methodology εd is found out to be slightly increases with proton fluence except at the fluence 1013 p/cm2 where material shows maximum crosslinking. The variations of the biological interaction with εd of PET material are correlated. Proton beam modified PET microfibre is therefore accepted to have further potential applications in radiation processing tissue response microfibre, fabrication of medical devices etc.
