Treated Surface
t.1S· polystyrene cell culture vessels arc surface modified using either
corona discharge (flasks, dishes and plmes) or gas-plasma (roller
bottles and culture tubes)."] hesc processes generate highly energetic
oxygen ionswhich grail untn the surface PuIYSI}rene chains (Figure I.)
so that the surface becomes hydrophi lic and negatively charged when
medium is added. The more oxygen that is incorporated nil 10 the
surface the more hydrophi lic it becomes and the better it is for cell
anachmcnt and spreading.
