Lipid Vesicles Replace Blood in New Bacteria Test

Beta-hemolytic bacteria are those pathogens that are frequently to blame for illnesses that are spread among school children like Streptococcus, or those like Listeria that cause many foodborne illnesses. The current test involves streaking a patient sample onto blood agar plates. More...

Automated Slide-Based Approach Introduced for CBCs

The most commonly performed clinical laboratory test is the complete blood count (CBC). Currently, laboratory CBC systems obtain cell counts and morphologic information by maintaining the blood cells in a liquid “flow” and by using the Coulter impedance-based orifice or laser-based cytometry.

World’s First Portable Fingerprint Drug Test Launched

The world’s first portable fingerprint-based drug screening system has been launched and is available now. The revolutionary system is hygienic and easy-to-use, collecting fingerprint samples in just five seconds and delivering simultaneous screening results in less than ten minutes for the four main drug groups: cocaine, opiates, cannabis and amphetamines.

The device can be plugged into the handheld potentiostat, at left (Photo courtesy of Purdue University, Aniket Pal).

Disposable POC Device Introduced for Low-Resource Areas

A recent paper described a novel diagnostic device fabricated from various types of paper to be used for point-of-care testing in areas lacking electricity and other resources. More...

Malaria Diagnosis Employs Hydrophilic-Treated Plastic Plates

Malaria is a red blood cell (RBC) infection caused by Plasmodium parasite and to determine RBC infection rate, which is essential for malaria study and diagnosis, microscopic evaluation of Giemsa-stained thin blood smears on glass slides is performed. More...

New Ultrafast Method Determines Antibiotic Resistance

Antibiotic resistance is a growing medical problem that threatens human health globally. One important contributory factor in the development of resistance is the incorrect use of antibiotics for treatment. More...

Smartphone-Based Analyzer Designed for Sample Testing

A handheld spectrophotometer that uses a smartphone camera to measure changes in absorption of natural light or emission of fluorescent light is the key to a mobile instrument that can evaluate biological samples with the accuracy of clinical laboratory analyzers but at a fraction of the cost.
