POC Test Based on Quantum Dots Detects Antibody Responses

Point-of-care (POC) assays, which can be performed at or near the site of care with a rapid turnaround time, are pivotal to transforming global disease control efforts, particularly in resource-constrained settings where access to laboratory facilities is limited. More...

Flow Cytometry Improved Updated Spectral Analyzer

Flow cytometry aims to count the number, size, granularity, and other properties of cells in a heterogeneous population. Standard flow cytometry lasers excite certain fluorescent markers (fluorochromes, antibodies, or stains) on a cell as it passes through the beam. More...

CSF Test Developed for Uncommon Brain Diseases

Scientific studies have linked the abnormal deposition of tau in the brain to at least 25 different neurodegenerative diseases. However, to accurately diagnose these diseases, brain tissue often must be analyzed after the patient has died. More...

PCR Kit Developed for Detection of Q-fever Pathogen

Coxiella burnetii is an obligate intracellular bacterium that causes Q fever in animals and humans. The infection results from inhalation of a spore-like small-cell variant, and from contact with the milk, urine, feces, vaginal mucus or semen of infected animals. More...

Breath Analysis May Replace Blood Sampling to Monitor Drug Usage

A simple and non-invasive technique to collect exhaled breath condensate (EBC) from chronic pain patients was developed, and its usefulness was confirmed by comparing metabolites in breath and blood samples following use of different analgesic opioid drugs. More...
