Development of medical nano strips

A new technology, with potential applications in research and clinical research, including early detection of disease, has been invented and developed by researchers at the University of Queensland (UQ).

Dr. Krassen Dimitrov, of UQ's Institute of Biotechnology and Nanotechnology, has developed photomultiplier "Barcodes" , called nanotubes, with higher sensitivity and accuracy than current detection methods. now on.

This work has been published in the prestigious International Journal of 'Nature Biotechnology'.

Dr Dimitrov said nanorods bind to RNA molecules to allow for digital analysis of gene expression.

'Because this system can accurately measure the number of biological molecules present, we can get an extremely accurate and sensitive picture of gene expression at a particular time'. Dr. Dimitrov said.

'This quantitative data is superior to other gene expression analysis systems, such as Microarrays, which rely on similar fluorescence measurements, with lower accuracy and narrow range '.

'Nanoscale is a technology development that is important for both research and clinical areas. We will be able to more accurately detect molecules associated with diseases and go back to find responsible genes. "

He said the technology does not rely on enzymatic processes, thus reducing the risk of bias and can be applied under different conditions.

Dr. Dimitrov is currently working on the next step of developing nano barcodes that are cheaper, more accurate and more sensitive.
