HOUSTON: Scientists have developed a portable saliva-based smartphone testing platform for COVID-19 which they claim can provide results within 15 minutes without the need for resource-intensive laboratory methods.
The new approach, described in the journal Science Advances, pairs a fluorescence microscope readout device with a smartphone to determine the quantity of virus in a patient sample.
In the study, the scientists, including Bo Ning from Tulane University School of Medicine in the US, used an assay made of CRISPR/Cas12a molecules to test 12 people infected with the novel coronavirus and six healthy controls, which was then read out using the smartphone platform.
LOS ANGELES: A smart ring that generates continuous temperature data may flag COVID-19 in its very early stages, even in cases when the coronavirus infection is not suspected, a new study says.
According to the research, published in the journal Scientific Reports on Monday, the device can be a better illness indicator than a thermometer, and may lead to earlier isolation and testing, curbing the spread of diseases like COVID-19.
In the study, scientists, including those from the University of California San Francisco analysed data from 50 people previously infected with the novel coronavirus and found that data obtained from the smart ring accurately identified higher temperatures in people with symptoms of COVID-19.
