Micro-patterned plasma polymer films for bio-sensing

Sensing and Actuation for Micro Bio Robots

Scaling down the size of robots enables new ways of exploring and manipulating microscale environments. Specifically in the field of biology, microrobots can be a tool for single cell analysis; such as for manipulating cells [1], measuring cell interactions [2] and cell surgery [3]. To create microrobots, we need to miniturize actuation and sensing capability to the cell scale. Bacteria have be...

Electrosynthetically patterned conducting polymer films for investigation of neural signaling.

The ion-mediated conduction and versatility of device fabrication of conducting polymers provide a route to the study of neural signaling. Patterned junctions of conducting polypyrrole have been electropolymerized on commercially available microelectrode arrays, with typical dimensions 200 mum between electrodes, each electrode being 30 mum in diameter. Tetrabutylammonium perchlorate or sodium ...

Phase separation of ultrathin polymer-blend films on patterned substrates

The phase separation of ultrathin polymer-blend films of polystyrene and polybutadiene on microcontact printed alkanethiol patterns with hydrophobic and hydrophilic end groups (2CH3 and 2COOH! is investigated by atomic force microscopy. Simulations suggest that the phase-separation morphology can be controlled through patterns that modulate the polymer-surface interaction, and this concept is v...
