'Genetic barcode' could help predict and prevent disease

Until the present age, human endeavour to search the cure for diseases. Various Studies for diseases are processing all over the world.

The University of Queensland has developed a genetic barcode that could predict and prevent diseases such as cancer before symptoms present. Doctor Krassen Dimitrov from the University of Queensland has produced fluorescent barcodes called nanostrings, which are mixed with blood to identify the make-up of different genes.The glowing mixture is scanned, and computer software is used to identify the molecular pattern in the gene.Doctor Dimitrov says the technology will be used to identify how diseases occur.

Genetic barcodes are like signature motifs and they have different colours that are spatially separated so a sequence of green, red and blue can be seen that is one molecule of a particular gene. If a different sequence is shown, that’s a molecule of different gene.

Dr Dimitrov assures the technology could predict and prevent diseases before symptoms appear.

If each individual molecule can be detected and count them digitally like items in a warehouse, human can inventories the gene expression levels for many different genes simultaneously.

Genetic Barcode is being further studied in University of Queensland at the moment and it has a good prospect.
