Micro-total analysis system for virus detection: microfluidic pre-concentration coupled to liposome-based detection.

Comparison between Micro and Tube Virus Neutralization Tests for Detection of Serological Responses to Infectious Bursal Disease Virus Following Vaccination

Simultaneous detection of duplex DNA oligonucleotides using a SERS-based micro-network gradient chip.

We report the development of a programmable surface-enhanced Raman scattering (SERS)-based micro-network gradient platform to simultaneously detect two different types of DNA oligomer mixtures. The utility of this platform was demonstrated by quantitative analysis of two breast cancer-related (BRCA1) DNA oligomer mixtures. To generate on-demand concentration gradients, the microfluidic circuit ...

Development of a microfluidic biosensor module for pathogen detection.

The development of a microfluidic biosensor module with fluorescence detection for the identification of pathogenic organisms and viruses is presented in this article. The microfluidic biosensor consists of a network of microchannels fabricated in polydimethylsiloxane (PDMS) substrate. The microchannels are sealed with a glass substrate and packed in a Plexiglas housing to provide connection to...

Pre-concentration and Determination of Low-traces of Copper Ions in Different Mediums Using Dispersive Liquid-liquid Micro-extraction (DLLME)

In the paper, in order to pre-concentrate and measure the low values of Cu ions, the new, simple,quick and very sensitive method of Dispersed Liquid-Liquid Micro Extraction (DLLME) coupledwith flame Atomic Absorption spectrometry (AA) has been utilized. The DLLME techniquecoupled with AA )AA-DLLME) was run inside one narrow tube which constitute aqueous samples.In this m...

Microfluidic Paper-Based Analytical Devices (μPADs) and Micro Total Analysis Systems (μTAS): Development, Applications and Future Trends

Microfluidic paper-based analytical devices and micro total analysis systems are relatively new group of analytical tools, capable of analyzing complex biochemical samples containing macromolecules, proteins, nucleic acids, toxins, cells or pathogens. Within one analytical run, fluidic manipulations like transportation, sorting, mixing or separation are available. Recently, microfluidic devices...
