Patterning multilayers of molecules via self-organization.
The electric dipole interaction among adsorbate molecules may cause them to form regular nanopatterns. In a multilayer system, the self-organization of each layer is also influenced by the underlying layers. This Letter develops a phase field model to simulate the molecular patterning process. The study reveals self-alignment, scaling down of size, and the effect of guided self-assembly with em...
متن کاملAxon guidance molecules in vascular patterning.
Endothelial cells (ECs) form extensive, highly branched and hierarchically organized tubular networks in vertebrates to ensure the proper distribution of molecular and cellular cargo in the vertebrate body. The growth of this vascular system during development, tissue repair or in disease conditions involves the sprouting, migration and proliferation of endothelial cells in a process termed ang...
متن کاملPatterning Molecules Multitasking in the Nervous System
Classical patterning molecules that were previously implicated in controlling cell fate choices in the nervous system have recently been shown to play additional roles in axon guidance and synaptogenesis. Bone morphogenetic proteins (BMPs), Sonic hedgehog (Shh), Wnts, and fibroblast growth factors (FGFs) all participate in multiple acts of controlling neuronal circuit assembly. Depending on the...
متن کاملLight activated patterning of dye-labeled molecules on surfaces.
This Communication describes a novel method for patterning proteins, ligands, or other organic/inorganic species onto solid substrates. The process works by linking the moiety of interest to a fluorophore that can be subsequently photobleached and bound to the interface. The technique can be performed in aqueous solution and allows several species to be addressed onto the surface simultaneously...
متن کاملProgrammable motion and patterning of molecules on solid surfaces.
Adsorbed on a solid surface, a molecule can migrate and carry an electric dipole moment. A nonuniform electric field can direct the motion of the molecule. A collection of the same molecules may aggregate into a monolayer island on the solid surface. Place such molecules on a dielectric substrate surface, beneath which an array of electrodes is buried. By varying the voltages of the electrodes ...
