Over the past two decades, self assembled monolayers (SAMs) (Love et al., 2005; Smith et al., 2004; Ulman, 1996) have been extensively studied due to their many applications in various fields such as electrochemistry (Eckerman et al., 2010), biosensors (Nyquist et al., 2000), protein separation (Chun and Stroeve, 2002) and enantiomer separation (Mastai, 2009). SAMs are organic assemblies formed...

Quantitative comparisons of space-time activity-travel patterns have been made at length in regional science. Traditionally, Euclidean Hamming distances have been widely used to measure the similarity between activity-travel patterns that involve several attribute dimensions such as activity type, location, travel mode, accompanying person, etc. Other techniques, such as pattern recognition in ...

This report describes the usc of surfacc plasmon spectroscopy to study the effect of surfacc wettability on the nonspecific adsorption of proteins and dctcrgcnts to self-assembled monolayers (SAMs) of alkanethiolatcs on gold. Thc adsorption of both proteins and detcrgcnts to uncharged SAMs showed a gencral depcndcncc on the wettability of the surface as determincd by thc contact anglc of watcr ...

This report describes a method for patterning ligands onto mixed SAMs of alkanethiolates on gold by microcontact printing (μCP). The mixed SAMs were made from thiols presenting terminal tri(ethylene glycol) groups (HS(CH2)11(OCH2CH2)3OH, 1) and terminal hexa(ethylene glycol)-CH2CO2H groups (HS(CH2)11(OCH2CH2)6OCH2CO2H, 2). Ligands were printed using a two-step procedure. The carboxylic acid gro...

We present PRISMA, a parametric framework for modeling distributed and mobile systems with different communication policies, defined as synchronization algebras with mobility (SAMs). This allows to choose each time the SAM that corresponds to the real synchronization used, and also to prove properties for different synchronization models at once. The paradigm we propose is based on process calc...

Two ideas for characterizing the local structure in mixed self-assembled monolayers (SAMs) were introduced. First, to use thermal desorption mass spectrometry (TD-MS) to probe nearest neighborhoods in the mixed monolayers. Second, to use hydrogen/deuterium exchange as a probe of the accessibility of acidic protons to exchange. Neighborhood interactions provided an opportunity to observe microsc...

In the field of the functionalisation of surfaces for biological applications, we have developed Self-Assembly monolayers (SAMs) of isocyanates on oxidized silicon wafers (1,0,0) by reaction of isocyanatodecyltrichlorosilane with the Si-OH groups of the surface. Excellent reactivity of the isocyanate monolayer with different nucleophiles was demonstrated. In particular, the semicarbazide group ...

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...
