Laser-based patterning for fluidic devices in nitrocellulose

Three-dimensional wax patterning of paper fluidic devices.

In this paper we describe a method for three-dimensional wax patterning of microfluidic paper-based analytical devices (μPADs). The method is rooted in the fundamental details of wax transport in paper and provides a simple way to fabricate complex channel architectures such as hemichannels and fully enclosed channels. We show that three-dimensional μPADs can be fabricated with half as much pap...

Paper-Based Fluidic Devices: From Fabrication to Assay Quantification

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...

Nanosecond Laser Surface Patterning of Bio Grade 316L Stainless Steel for Controlling its Wettability Characteristics

In this work, potential of the nanosecond laser processing technique on manipulating the surface wettability of 316L bio grade stainless steel is investigated. Results show that the steel wettability toward water, improves significantly after the laser treatment. Different analyses are assessed in correlation with wettability using Scanning Electron Microscope (SEM), Scanning Tunneling Microsco...
