Sydney, July 30, 2025, Scientists at the University of Queensland have developed a low cost, open source device for measuring DNA concentration, using components made with a standard 3D printer.
Known as the Do It Yourself Nucleic Acid Fluorometer (DIYNAFLUOR), the tool is designed to offer an affordable alternative to commercial DNA fluorometers, which are often too expensive for many labs and researchers.
In a statement on Wednesday, the University of Queensland (UQ) said its Australian Institute for Bioengineering and Nanotechnology (AIBN) led the development.

Fluorometers are key tools in DNA sequencing, a process essential for detecting diseases, advancing treatments, and identifying species. The new device, built from easily available parts, can be assembled in under a day for about 60 Australian dollars (approximately 39 US dollars).
“It’s available with free instructions online and doesn’t require advanced skills or special tools,” said Will Anderson, the device’s designer at AIBN.
Once assembled, the device works by shining a light beam on dyed DNA in a sample. The fluorescent response it produces is used to calculate DNA concentration, which is then displayed on a connected computer.
“This is crucial information that can tell you whether you can proceed with more expensive tests and sequencing,” Anderson said.
Tests showed that the DIYNAFLUOR matches the accuracy and sensitivity of commercial models, making it a practical option for labs in remote, under-resourced, or educational settings.
