New protein-based nano-switches could lead to faster, more accurate diagnostic tests

Posted by in categories: bioengineering, biotech/medical, nanotechnology

QUT researchers have developed a new approach for designing molecular ON-OFF switches based on proteins which can be used in a multitude of biotechnological, biomedical and bioengineering applications.

The research team demonstrated that this novel approach allows them to design and build faster and more accurate diagnostic tests for detecting diseases, monitoring water quality and detecting environmental pollutants.

Professor Kirill Alexandrov, of the QUT School of Biology and Environmental Science, lead scientist on the CSIRO-QUT Synthetic Biology Alliance and a researcher with the ARC Centre of Excellence in Synthetic Biology, said that the new technique published in the prestigious scientific journal Nature Nanotechnology demonstrated that protein switches could be engineered in a predictable way.
