Microhole Chip Rapidly Identifies Tumor Cells

The higher the concentration of tumor cells in the bloodstream, the greater the risk of metastasis. The number of circulating tumor cells indicates how well a patient is responding to therapy. More...

Sensor Technology May Improve Cancer Diagnosis

Researchers have developed a plasmonic sensor that could provide reliable early detection of biomarkers for many forms of cancer and eventually for other diseases. The sensor detected cancer biomarker carcinoembryonic antigen (CEA) to the magnitude of only 1 nanogram/milliliter. More...

New Diagnostic Products Detect Prostate Cancer

A novel sample collection device was designed to support a urine-based non-invasive "liquid biopsy" molecular diagnostic test that determines the risk for developing high-grade prostate cancer. More...

A new conducting polymer was developed for detecting specific interaction of trisaccharide with hemagglutinin in the envelope of the human influenza A virus (H1N1) by electrical manners (Photo courtesy of the Tokyo Medical and Dental University).

Biosensor Technology Enables Rapid Detection of Flu Virus

A research team has developed a voltage-sensor for early detection of influenza virus A (H1N1) that is almost 100 times more sensitive than conventional tests, and can distinguish between human and avian strains. More...

Antimalarial Compound Improves Forensics of Bloodstains

Forensic investigators often use a luminol chemiluminescence test to detect latent bloodstains at crime scenes. Now, researchers have found that combining luminol with the antimalarial drug artemisinin, a natural peroxide, reduces the risk of false positives compared to the traditional method that mainly uses hydrogen peroxide or sodium perborate as coreactants. They also obtained test results using a smartphone, which could provide highly accurate on-scene analyses. More...

Enzyme Deficiency Diagnosed with Rapid Tests

Glucose-6-phosphate dehydrogenase (G6PD) is a rate-limiting enzyme of the pentose phosphate pathway and is closely associated with the hemolytic disorders among patients receiving anti-malarial drugs, such as primaquine. More...
