Abstract
Monolayer of 3-(triethoxysilyl) propyl isocyanate was prepared on the slide by self-assembled technique. X-ray photoelectron spectroscopy (XPS) was employed to analyze the elementary composition of the film. Contact angle of distilled water was measured to characterize the surface state. It was shown that 3-(triethoxysilyl) propyl isocyanate had been successfully assembled on the slide. The increase of contact angle to 80° demonstrated that the hydrophobicity of the surface of chip was increased significantly. Moreover, further self-assembly of bovine serum albumin (BSA) on 3-(triethoxysilyl) propyl isocyanate was also carried out with the advantages such as simple and convenient preparation. Therefore, the potential of broader applications in the modification of micro-channel in the μ-TAS system, the immobilization of protein or peptide and the surface modification of materials are all expectative.
