Electrical Detection of Self-Assembled Polyelectrolyte Multilayers by a Thin Film Resistor
The build up of polyelectrolyte multilayers (PEMs) was observed by a silicon-on-insulator (SOI) based thin film resistor. Differently charged polyelectrolytes adsorbing to the sensor surface result in defined potential shifts, which decrease with the number of layers deposited. We model the response of the device assuming electrostatic screening of polyelectrolyte charges by mobile ions within ...
متن کاملSelf-assembled multilayers of nanocomponents.
We show it is possible to assemble nanoparticle-polymer layers in a controllable manner dictated by the difference in nano-object morphology and dielectric properties. A thin (10-100 nm) layer of the two components is spin coated onto a solid substrate and the system thermally aged to activate a cross-linking process between polymer molecules. The nanoparticles segregate to the solid substrate ...
متن کاملSpin coating nanopatterned multielemental materials via self-assembled nanotemplates.
Spin coating of multicomponent precursor solutions was employed in conjunction with block copolymer nanotemplates to fabricate nanopatterned functional multielemental materials. Nanodot and nanowire arrays of several multielemental materials exhibiting optoelectronic and multiferroic properties have been fabricated on various substrates to demonstrate the versatility of our approach. The shape,...
متن کاملSelf-assembled particle monolayers on polyelectrolyte multilayers: particle size effects on formation, structure, and optical properties
Monolayers of charged polystyrene latex particles ranging in size from 100 nm to 10 m were deposited on oppositely charged polyelectrolyte multilayers (PEMs) by electrostatic interactions and capillary forces. Ultrathin PEMs (∼30 nm) formed on a glass slide provided an e p i a l s c a ©
متن کاملSelective depositions on polyelectrolyte multilayers: self-assembled monolayers of m-dPEG acid as molecular template.
This paper describes the fabrication of self-assembled monolayer (SAM) patterns of m-d-poly(ethylene glycol) (m-dPEG) acid molecules onto polyelectrolyte multilayers (PEMs). The patterned SAMs on PEMs were created by ionic interactions using microcontact printing (microCP) technique. The created m-dPEG acid monolayer patterns on PEMs act as resistive templates, and thus further depositions of c...
