Self-Organization of Polymer Brush Layers in a Poor Solvent
Synthesis of densely grafted polymer brushes from good solvent polymer solutions is difficult when the surface interaction is only weakly attractive because of the strong stenc repulsion between the polymer chains To circumvent this difficulty we graft polymer layers in a poor solvent to exploit attractive polymer-polymer interactions which largely nullify the repulsive stenc interactions. This...
متن کاملDiatom cells grown and baked on a functionalized mica surface.
We demonstrate the cultivation of diatom cells on a functionalized mica surface and the preparation of frustules on a mica surface by baking. Diatom cells were successfully grown on a mica surface treated with 3-aminopropyltriethoxysilane. After baking at 400 degrees C for 2 h, frustule structures without the organic components of the diatom cells were successfully observed by scanning electron...
متن کاملComplete surface control of peptide nanospheres with detachable and attachable polymer brush layers.
The surfaces of biodegradable peptide nanospheres with density-controllable poly(ethylene glycol) (PEG) brush layers were amenable to high levels of control, from hydrophilic 'stealth' properties to hydrophobic adsorptive properties depending on the PEG density in response to environmental conditions -'intelligent' properties that are expected to be useful for novel drug delivery systems.
متن کاملSurface-grafted polysarcosine as a peptoid antifouling polymer brush.
Poly(N-substituted glycine) "peptoids" are a class of peptidomimetic molecules receiving significant interest as engineered biomolecules. Sarcosine (i.e., poly(N-methyl glycine)) has the simplest side chain chemical structure of this family. In this Article, we demonstrate that surface-grafted polysarcosine (PSAR) brushes exhibit excellent resistance to nonspecific protein adsorption and cell a...
متن کاملSurface plasmon enhanced emission from dye doped polymer layers.
We have experimentally verified that the emission of visible light from dye doped polymers can be enhanced with the use of surface plasmon coupling. By matching the plasmon frequency of a thin unpatterned silver film to the emission of a dye doped polymer deposited onto this metal surface, we have observed a eleven-fold enhancement of light emission. By patterning the silver layer, we estimate ...
