Ideal method for rapid disease testing

In the pandemic age of telehealth and new technologies, remote site lab or point-of-care (POC) testing of biofluids is a potentially rapid and non-invasive way to test for most diseases—including COVID-19.

Silver nanocubes make point-of-care diagnostics easier to read

Engineers at Duke University have shown that nanosized silver cubes can make diagnostic tests that rely on fluorescence easier to read by making them more than 150 times brighter. Combined with an emerging point-of-care diagnostic ...

New nanosensor detects cancer biomarkers in drop of blood

Looking for cancer biomarkers in blood is a promising method for detecting metastatic cancer. It is less demanding than imaging techniques like MRI (magnetic resonance imaging). The main challenge to overcome is the extremely ...

Portable device helps doctors diagnose sepsis faster

EPFL researchers have developed a highly sensitive and portable optical biosensor that stands to accelerate the diagnosis of fatal conditions like sepsis. It could be used by ambulances and hospitals to improve the triage ...

Chip-based optical sensor detects cancer biomarker in urine

For the first time, researchers have used a chip-based sensor with an integrated laser to detect very low levels of a cancer protein biomarker in a urine sample. The new technology is more sensitive than other designs and ...
