Force–separation curves recorded for symmetric systems of the self-assembled monolayers (SAMs) in a PBS (phosphate-buffered saline) buffer solution. The effect of the number of the EG unit was investigated. The chemical structures of the thiols constituting the SAMs are EG1-OH: HS-(CH2)11-O-CH2-CH2-OH, EG2-OH: HS-(CH2)11-(O-CH2-CH2)2-OH, EG3-OMe: HS-(CH2)11-(O-CH2-CH2)3-O-CH3, and EG6-OH: HS-(CH2)11-(O-CH2-CH2)6-OH.
