PLL-PEG Coating stability
Previously, we showed that our method of pll-peg coating is effective for creating non-fouling substrate which can prevent protein adsorbtion, and this method can be used to create a non-fouling pattern on the surface.
In the next step, we wanted to make sure that whether our peg coating is effective for preventing cell adhesion or not. Additionally, we wanted to evaluated the stability of this patterning on our samples. So, we decided to have a uniform coating of pll-peg on the surface, and compare cell adhesion on PEG-coated surfaces versus non-coated SiO2.
One of the important points about the images that we took from the samples is that the cells that were found on the peg coated samples were generally located on the borders of gasket. These areas can be considered as non-coated areas on the samples.
