'Unboil an egg' machine creates improved bacteria detector


Traditional fluorescent dyes to examine bacteria viability are toxic and suffer poor photostability—but using the VFD has enabled the preparation of a new generation of aggregation-induced emission dye (AIE) luminogens using graphene oxide (GO), thanks to collaborative research between Flinders University's Institute for NanoScale Science and Technology and the Centre for Health Technologies, University of Technology Sydney.To get more news about Egg breaker machine, you can visit dinneregg official website.

Using the VFD to produce GO/AIE probes with the property of high fluorescence is without precedent—with the new GO/AIE nanoprobe having 1400% brighter high fluorescent performance than AIE luminogen alone.

"It's crucial to develop highly sensitive ways of detecting bacteria that pose a potential threat to humans at the early stage, so health sectors and governments can be informed promptly, to act quickly and efficiently," says Flinders University researcher Professor Youhong Tang.

"Our GO/AIE nanoprobe will significantly enhance long-term tracking of bacteria to effectively control hospital infections, as well as developing new and more efficient antibacterial compounds."

The VFD is a new type of chemical processing tool, capable of instigating chemical reactivity, enabling the controlled processing of materials such as mesoporous silica, and effective in protein folding under continuous flow, which is important in the pharmaceutical industry. It continues to impress researchers for its adaptability in green chemistry innovations.Developing such a deep understanding of bacterial viability is important to revise infection control policies and invent effective antibacterial compounds," says lead author of the research, Dr. Javad Tavakoli, a previous researcher from Professor Youhong Tang's group, and now working at the University of Technology Sydney.

"The beauty of this research was developing a highly bright fluorescence dye based on graphene oxide, which has been well recognized as an effective fluorescence quenching material."

The type of AIE luminogen was first developed in 2015 to enable long-term monitoring of bacterial viability, however, increasing its brightness to increase sensitivity and efficiency remained a difficult challenge. Previous attempts to produce AIE luminogen with high brightness proved very time-consuming, requires complex chemistry, and involves catalysts rendering their mass production expensive.
