New chip makes testing for antibiotic-resistant bacteria faster, easier

We live in fear of 'superbugs': infectious bacteria that don't respond to treatment by antibiotics, and can turn a routine hospital stay into a nightmare. A 2015 Health Canada report estimates that superbugs have already cost Canadians $1 billion, and are a "serious and growing issue." Each year two million people in the U.S. contract antibiotic-re ...

Use your smartphone for biosensing

An Australian research team has shown that smartphones can be reconfigured as cost-effective, portable bioanalytical devices, with details reported in the latest edition of the Open Access Journal 'Sensors'.

Faster, portable microbial analysis in the field

Until recently, it took hours – sometimes days – to analyze biological samples after they were frozen in the field and brought back to the laboratory. But now there is a faster, cheaper and smaller way ...

New test detects drug use from a single fingerprint

Research published today in the journal Analyst has demonstrated a new, noninvasive test that can detect cocaine use through a simple fingerprint. For the first time, this new fingerprint method can determ ...

Automated counting of tumor cells in blood

Biological and medical scientists have been using flow cytometry to count cancer cells for the past 40 years. But the large instruments are expensive and can only be operated by trained personnel. By contrast ...

A phone with the ultimate macro feature

If you thought scanning one of those strange, square QR codes with your phone was somewhat advanced, hold on to your seat. Researchers at the University of California, Los Angeles (UCLA) have recently developed ...

Test can smell ketosis

VTT has developed a quick, easy-to-use ketosis test for consumers that can detect acetone on exhaled breath. The test will benefit diabetics and dieters in particular, but it can easily be adapted to other uses as well, such ...
