I carried out experiments to test the adsorption of 1 mg/ml of BSA on NHS-PEG surfaces.This time the APTES layer was deposited from solution phase on to the silicon surface in contrast to vapor phase (YES) deposition. Again adsorption of BSA on different layers was confirmed using spectroscopic ellipsometry. Protocol for surface modification: The chips were left…
The AIM of this experiment was to see the effect of surfaces modified with PEGs (Polyethylene glycol) to protein adsorption. The PEG that I used for the current study is MS-PEG8 (Methyl-PEG8-NHS) which is Amine reactive. Method: For the current experiment I used planar silicon chips which have ~ 142 nm of thermally grown oxide….
All the data presented below was generated by Alex from Adarza Biosystems, Inc. Introduction: Chemical vapor deposition of 99% APTES (3-Aminopropyltriethoxysilane) on planar silicon chips was accomplished using the new vapor deposition system (YES: Yield Engineering Systems). In addition to vapor deposition of chemical moieties, YES system is also equipped with plasma cleaner that enables…
