What is the most effective cleaning/activation method of the glass...
I am trying to treat the glass slide with (3-trimethoxysilyl)propyl methacrylate (TMPMA) for further immobilizing PEG Dimethacrylate (PEGDM). Before the treatment, I did the ultrasonic cleaning with acetone and ethanol, and then O2 plasma treatment for 3-5min. After plasma treatment, the glass slides were immediately put into TMPMA solution for 30min, and then I would spin the PEGDM onto slide. But the PEGDM layer was easy to get peel off from the glass slide. It seems like the -OH groups on glass slide were not enough with O2 plasma, which causes TMPMA treatment is not effective enough. Would O2 plasma treatment create large amount -OH groups on glass surface ? Is there any better way to activate glass surface ?
