We describe a method to pattern arbitrary-shaped silane self-assembled monolayers (SAMs) with nm scale resolution using DNA nanostructures as templates. The DNA nanostructures assembled on a silicon substrate act as a soft-mask to negatively pattern SAMs. Mixed SAMs can be prepared by back filling the negative tone patterns with a different silane.
Magnetic nanoparticles (NPs) have been assembled in films by using self-assembled monolayers (SAMs) of organic molecules. SAMs were prepared by the reaction of organotrialkoxysilanes with surface silanol groups of silicon wafers. SAMs were prepared and their surface was decorated either by amine or thymine groups which have the ability to immobilize iron oxide nanoparticles as monolayers. These...
Anion templation is used to assemble novel redox-active bis-ferrocene functionalised rotaxane self-assembled monolayers (SAMs) on to gold electrode surfaces; after template removal, the unique SAM rotaxane binding domain is capable of selectively sensing chloride ions electrochemically.
We describe a photolithographic method for the direct modification and micropatterning of the surface chemical structure of self-assembled monolayers. End-functional azobenzene alkanethiols are designed and synthesized so that, when self-assembled onto gold substrates, an acid-sensitive tert-butyl ester end group is positioned at the air-monolayer interface. Upon exposure to UV radiation in the...
