Photothermal response of polymer microcantilever with metal coating in fluids

Microcantilever mechanics in flowing viscous fluids

Polymer Processing with Supercritical Fluids

Supercritical fluids have a unique and valuable potential for the enhanced processing of many materials. This review describes research in the applications of supercritical fluids to polymer processing. The ability of supercritical carbon dioxide to swell and plasticize polymers is crucial to the impregnation, extraction, and modification of polymeric materials. This plasticization also reduces...

In vivo evaluation of mucoadhesive properties of nanoliposomal formulations upon coating with trimethylchitosan polymer

Objective(s): Drug delivery via mucosal routes has been confirmed to be effective in inducing strong immune responses. Liposomes could enhance immune responses and mucoadhesive potentials, make them useful mucosal drug delivery systems. Coating of liposomes by mucoadhesive polymers succeeded in enhancing immune responses. Our studies aim at preparation and characterization of trimethylchitosan-...

Electromechanical response of ionic polymer-metal composites

An ionic polymer-metal composite ~IPMC! consisting of a thin Nafion sheet, platinum plated on both faces, undergoes large bending motion when an electric field is applied across its thickness. Conversely, a voltage is produced across its faces when it is suddenly bent. A micromechanical model is developed which accounts for the coupled ion transport, electric field, and elastic deformation to p...

Glucose-responsive polymer brushes for microcantilever sensing†‡

Glucose responsive polymer brushes were synthesized on gold substrates and microcantilever arrays. The response properties of these brushes were evaluated by exposing them to different glucose concentrations for a range of pH values. This work demonstrates the potential for polymer brush-functionalized micromechanical cantilevers as glucose detectors. Furthermore, the work demonstrates that sti...
