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 ...

Blood samples from the zoo help predict diseases in humans

The zoos of Saarbrücken and Neunkirchen are home to penguins, Asian elephants and many other species. Since they come from different continents, blood samples are regularly taken from the animals to check their health. These ...

Painless skin patch collects fluid for diagnostic testing

Although blood contains a wealth of potential biomarkers of disease, it can be challenging to obtain and analyze. There's the anxiety patients experience when a large needle has to be stuck into a vein, and for many tests, ...

Biomarker

A biomarker is a substance used as an indicator of a biologic state. It is a characteristic that is objectively measured and evaluated as an indicator of normal biologic processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention.
