GeneBalls: barcoding DNA

10.09.2004


Millions of genetic tests using just one drop of blood.



Queensland PhD student Angus Johnston has invented a unique technology with the potential to test for hundreds of diseases, cancers and genes in one, cheap, test. He hopes that within five years the technology will be available in a desktop unit for less than AU$30,000. “This is a unique, patented technology that has the potential to revolutionise genetic testing,” said Angus Johnston, PhD student and co-inventor of the technology. “A simple machine could be installed in a doctor’s surgery which would give almost instantaneous feedback on which diseases the patient is susceptible.”

GeneBalls would not only help diagnosing cancer and other diseases, but also give an early warning for diseases like heart disease. With this early warning the patient can make lifestyle changes before any symptoms occur.


Geneballs can currently look at 12 genes in one test, but in the next 12 months we plan to increase this number to tens or hundreds of thousands. The existing technology, is too expensive and inaccurate for clinical applications.

Angus is one of 16 early-career scientists presenting their research to the public for the first time thanks to Fresh Science. The researcher who best meets the criteria of the national competition will present their work in the UK courtesy of British Council Australia.

It’s been an exciting journey for the student researcher. “I’ve had the opportunity to do a PhD that’s led to direct commercial outcomes,” says Angus. “It has given me two international patents and a shareholding in a company which is commercialising the technology.”

GeneBalls are tiny particles one tenth the diameter of a human hair and work like a barcode on items in a supermarket.

Each tiny bead contains a mixture of fluorescent dyes and is coated with DNA. If a patient has DNA the same as DNA on one of the GeneBalls, their DNA will stuck to the GeneBall.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
