Carboxyl PAMAM dendrimer (3.5 generation) was covalently coupled onto amine modified glass surface to prepare a monolayer of high density functional linkers. Activation of the carboxyl PAMAM surface and the subsequent immobilization of antibodies resulted in a high density protein microarray as compared to linear carboxyl linker surface. In addition, fluorescent labeled cell lysate showed extremely low nonspecific adsorption to the PAMAM modified surface, comparable to inert PEG surface. Thus, the carboxyl PAMAM modified surface is ideal for the generation of high density protein arrays for the detection of dilute antigens with superior sensitivity.

AbstractAlthough the self-assembly of organic ligands on gold has been dominated by sulfur-based ligands for decades, a new ligand class, N-heterocyclic carbenes (NHCs), has appeared as an interesting alternative. However, fundamental questions surrounding self-assembly of this new ligand remain unanswered. Herein, we describe the effect of NHC structure, surface coverage, and substrate temperature on mobility, thermal stability, NHC surface geometry, and self-assembly. Analysis of NHC adsorption and self-assembly by scanning tunneling microscopy and density functional theory have revealed the importance of NHC-surface interactions and attractive NHC-NHC interactions on NHC monolayer structures. A remarkable way these interactions manifest is the need for a threshold NHC surface coverage to produce upright, adatom-mediated adsorption motifs with low surface diffusion. NHC wingtip structure is also critical, with primary substituents leading to the formation of flat-lying NHC2Au complexes, which have high mobility when isolated, but self-assemble into stable ordered lattices at higher surface concentrations. These and other studies of NHC surface chemistry will be crucial for the success of these next-generation monolayers.
