Spoiled oranges shine light on malignant cells

Biomedical device passes the litmus test

16-Dec-2021

A University of Sydney PhD researcher is developing a cancer and serious disease-detecting biomedical probe that can be made from the juice of rancid oranges. Called a nanobiosensor – a tiny probe that uses fluorescence to signal cells' pH in terms of their acidity or alkalinity – it detects ...

World record broken for thinnest X-ray detector ever created

Highly sensitive and with a rapid response time, the new X-ray detector is less than 10 nanometres thick and could one day lead to real-time imaging of cellular biology

10-Nov-2021

Scientists in Australia have used tin mono-sulfide (SnS) nanosheets to create the thinnest X-ray detector ever made, potentially enabling real-time imaging of cellular biology. X-ray detectors are tools that allow energy transported by radiation to be recognised visually or electronically, like ...

Molecular probe maps misfolded proteome state in live cells

13-Jan-2020

The folding state of the proteins in live cells often reflect the cell’s general health. Australian scientists have developed a molecular probe that senses the state of the proteome—the entire set of the proteins—by measuring the polarity of the protein environment. The fluorescence signal of the ...
