Influence of Alkyl Chain Length of Biotin Terminated n-Alkanethiolate SAMs on a Molecular Recognition between Streptavidin and Biotin
E-mail:
In an attempt to investigate the influence of the chain length of n-alkanethiolate monolayers on a molecular recognition process of the streptavidin-biotin system, self-assembled monolayers (SAMs) of biotin-terminated n-alkanethiolates [HS(CH2)nX, where n= 11, 12, and 16] and their mixtures with 11-mercap-toundecanol (MUOH) were prepared on a gold surface. Experimental data obtained by surface analytical techniques, including optical ellipsometry, contact angle goniometry, and X-ray photoelectron spectroscopy (XPS), show that the packing density of biotin-terminated n-alkanethiolate SAMs is affected strongly by the number of alkyl chains of the n-alkanethiolates and that the SAMs of even-numbered alkyl chains are more oriented and closely packed than those of odd-numbered ones. The film thickness obtained by ellipsometry and the scanning tunneling microscopy (STM) images of streptavidin adsorbed on the mixed SAMs of biotin-terminated n-alkanethiolates with a diluent, MUOH, both indicate that the specific binding of streptavidin to biotin is optimized at very low mole fractions of the biotin-terminated n-alkanethiolates.
