(a) Schematic showing the surface modification of our parylene chips utilizing 3-aminopropyltriethoxysilane and glutaraldehyde for covalently immobilizing proteins. (b) Brightfield image of an inkjet droplet of IL-8 incubated on the parylene openings that have been treated with glutaraldehyde and aminosilane. (c) Fluorescent image collected in the 647nm emission wavelength following immunostaining, showing TGF-α covalently bound to the surface as a nanoarray of 600nm line features. (d) Fluorescent image similar to (c) but for IL-8 and collected in the 488nm emission wavelength.
