A new test designed at Imperial could pave the way for improvements in early-diagnosis of diseases such as cancer or viruses including HIV, which could in turn save lives.
The BBC reported that the test that can detect infection or disease molecules at ultra-low concentrations. The research was published in Nature Nanotechnology by Professor Molly Stevens [Materials]. Like litmus paper, the colour of the test liquid changes to signal whether the disease is present. At only a fraction of the cost of the tests currently used, this new technique could dramatically improve early diagnosis of diseases, such as HIV, in countries where resources for healthcare are stretched and conventional methods are unaffordable.
