HOT article: rapid identification of ‘bird-flu’

Reverse transcriptase PCR (RT-PCR) has been introduced as the most sensitive method for detecting and pathotyping the avian influenza virus (AIV) or ‘bird flu’, however the number of targets that can be amplified in a single run is limited.

Now chemists at the Technical University of Denmark have developed a device for the rapid and unambiguous detection of AIV by integrating DNA microarray-based solid-phase PCR on to a microfluidic chip. This combines the advantages of microfluidic devices, the high-throughput capabilities of microarrays and the superior specificity of solid-phase PCR. The whole process takes under an hour and uses a sample volume 10 times less than anything previously, meaning that this device can be widely employed by veterinarians for rapid on-site screening of AIV in wild and domestic poultries.
