Physical removal of metallic carbon nanotubes from nanotube network devices using a thermal and fluidic process.

Electronic and optoelectronic devices based on thin films of carbon nanotubes are currently limited by the presence of metallic nanotubes. Here we present a novel approach based on nanotube alkyl functionalization to physically remove the metallic nanotubes from such network devices. The process relies on preferential thermal desorption of the alkyls from the semiconducting nanotubes and the su...

Detection of Cryptosporidium in miniaturised fluidic devices.

Contamination of drinking water with the protozoan pathogen, Cryptosporidium, represents a serious risk to human health due to the low infectious dose and the resistance of this parasite to chlorine disinfection. Therefore, several countries have legislated for the frequent monitoring of drinking water for Cryptosporidium presence. Existing approved monitoring protocols are however time-consumi...

Simulation and Design of Extraction and Separation Fluidic Devices

We present the combination of a state control and shape design approaches for the optimization of micro-fluidic channels used for sample extraction and separation of chemical species existing in a buffer solution. The aim is to improve the extraction and identification capacities of electroosmotic micro-fluidic devices by avoiding dispersion of the extracted advected band. Résumé. Nous présento...

A simple and effective fluidic encapsulation protocol for bioMEMS devices

Biomedical micro-electromechanical systems (bioMEMS) and other biochips usually have exposed chip surfaces that interface with fluids containing biological elements. These chips require postprocessing for fluidic encapsulation to confine the spreading of fluids during experiments. An effective fluidic encapsulation protocol is reported here that simplifies this encapsulation procedure. The prot...
