Self-assembled monolayers: from ‘simple’ model systems to biofunctionalized interfaces

Self-assembled organic monolayers: model systems for studying adsorption of proteins at surfaces.

Self-assembled monolayers (SAMs) of omega-functionalized long-chain alkanethiolates on gold films are excellent model systems with which to study the interactions of proteins with organic surfaces. Monolayers containing mixtures of hydrophobic (methyl-terminated) and hydrophilic [hydroxyl-, maltose-, and hexa(ethylene glycol)-terminated] alkanethiols can be tailored to select specific degrees o...

Design and Application of a Fiber Pullout Test for Examining Controlled Interfaces in Fiber Reinforced Polymers

page 62 Abstract: A fiber pullout test for examining controlled interfaces in fiber reinforced polymers has been designed and demonstrated. This test has been utilized in determining interfacial fracture toughness for sapphire/epoxy single fiber composite specimens. Some of these specimens incorporated a self-assembled monolayer at the sapphire/ epoxy interface as a means of adhesion control—th...

The Role of Ligand Density in the Enzymatic Glycosylation of Carbohydrates Presented on Self-Assembled Monolayers of Alkanethiolates on Gold

The enzymatic modification of immobilized carbohydrates is important in protein trafficking,[1] viral and bacterial pathogenesis,[2] and cell migration.[3] Many model systems, including those that use polymers,[4] dendrimers,[5] and liposomes[6] to present carbohydrates, have provided information on the interactions between proteins and immobilized sugars. These systems, however, present carboh...

Fluorinated self-assembled monolayers: composition, structure and interfacial properties

Over the past several years, various fluorinated self-assembled monolayers (F-SAMs) on gold have been used to study the interfacial properties of fluorocarbon interfaces. This review focuses on the structures of selected F-SAMs and describes how the structures relate to various interfacial properties, such as wettability, friction, X-ray induced damage and ion-surface collisions. 2003 Elsevier ...
