Our surface force measurements revealed that strong water-induced repulsion operated between bioinert Au-supported EG3-OMe SAM. In contrast, there was no such repulsion observed for a bio-adhering Ag-supported EG3-OMe SAM. Surface-enhanced infrared absorption spectra showed that state of hydrogen bondings between interfacial water molecules near the EG3-OMe SAMs are different depending on the substrates. These results clearly indicate that interfacial water plays a key role in the bioinertness of the SAMs.
