Researchers develop diagnostic tool for detecting cryptosporidium

A handheld 'tricorder' that can test for biological contamination in real-time has been the dream of science fiction fans for decades. And UBC Okanagan engineers say the technology is closer to science fact than ever before.

Paper-based lateral flow device to detect uranium in groundwater

The presence of uranium in groundwater can lead to severe health problems, from renal failure to cancer. Standard methods to detect uranium involve time-consuming processes and expensive, non-portable equipment. Measurements ...

Using biosensors to deliver personalized doses of antibiotics

A team of eight EPFL students has come up with a portable biosensor that can measure the amount of vancomycin in a patient's blood stream, enabling doctors to better control the dosage and reduce harmful side effects. Their ...

Biosensor allows real-time oxygen monitoring for 'organs-on-a-chip'

A new biosensor allows researchers to track oxygen levels in real time in "organ-on-a-chip" systems, making it possible to ensure that such systems more closely mimic the function of real organs. This is essential if organs-on-a-chip ...

Improving biosensors for implantable use

EPFL scientists have developed new nanotube biosensors using synthetic biology, which improves their sensing capabilities in complex biofluids, such as blood and urine. The study is published in the Journal of Physical Chemistry ...

Detecting metabolites at close range

A novel concept for a biosensor of the metabolite lactate combines an electron transporting polymer with lactate oxidase, which is the enzyme that specifically catalyzes the oxidation of lactate. Lactate is associated with ...
