Handheld Device to Capture and Identify Viruses in Minutes

Researchers at Penn State have developed a handheld device called VIRRION that can capture and identify viral particles in samples within minutes. The device contains a “forest” of carbon nanotubes that capture and sort viral particles depending on their size, and then users can identify the viruses using Raman spectroscopy. The techniq (Read more...)

MolecuLight FDA Cleared to Detect Bacteria Infected Wounds

Knowing whether a wound is infected by a bacterial colony is important for monitoring patients and deciding the course of treatment. Currently, the standard of care is simply to assess the clinical signs and symptoms (CSS) related to the wound in question, but bacterial infections of wounds are typically not obvious until they’re at an [&hell (Read more...)

Smart Microscope Learns to Diagnose Infectious Diseases

Experienced professionals tend to be better than rookies partly because they know how to use the tools of their trade more effectively. Cytologists who evaluate cells under a microscope become more consistent and accurate when they know how to prep their apparatus to produce clear images. Researchers at Duke University have now given a microscope [ (Read more...)

Low Cost Turbidity Measurements Using a Fitness Tracker

Continuous monitoring of bacterial growth is a critical step in the biotechnology industry and in biological labs. These measurements are typically taken using large and bulky spectrophotometers that do not fit into incubators for real-time monitoring. Moreover, continuous monitoring is labor-intensive as it requires multiple samplings. Recent deve (Read more...)

Chip to Evaluate Health of Immune System from Blood Sample

Knowing how well a patient’s immune system is functioning may be very useful in diagnosing a disease and guiding the course of therapy. Researchers from Nanyang Technological University in Singapore are making this a reality, having developed a hybrid chip that assesses the health of white blood cells in a whole blood sample. The microfluidic (Read more...)

Microfluidic Device for Rapid Lyme Disease Diagnosis

Researchers at Columbia University have developed a microfluidic device that can diagnose Lyme disease in as little as 15 minutes. The device is particularly accurate in identifying antibody biomarkers that are present during early stage Lyme disease, raising hopes that it could be useful in detecting cases of early infection in a doctor’s of (Read more...)
