Point-of-Care HIV Diagnostics for Low Resource Regions: Interview with Jesse Lehga, VP at Diagnostics for the Real World

DRW (Diagnostics for the Real World), a company with headquarters in San Jose, California, and Cambridge, United Kingdom, has developed the SAMBA II, a point-of-care diagnostic device for the detection of infectious diseases, including HIV and HCV, for use in low-resource and/or remote regions. The system employs nucleic acid amplification to detec (Read more...)

Hybrid Infrared-Optical Microscope for Pathology Studies

When imaging tissues microscopically, pathology labs have to stain the samples to see the cellular shapes and structures within. This is not trivial and requires expertise, time, and related costs. Infrared light has the capability to help visualize biomedical samples without staining, but the wavelengths of such light make it incompatible with opt (Read more...)

Pill-Sized Chemical Heater for Point-of-Care Diagnostic Tests

Researchers at the University of Toronto have developed a miniaturized chemical heater that can precisely heat biological samples during diagnostic tests, but does not require electricity or any specialized equipment to work. The low-cost technology is based on the exothermic reaction that occurs when lithium encounters water, and the precise shape (Read more...)

Lensless Microscopy Chip for Diagnostic Applications

Researchers at the University of Connecticut have developed a lensless microscope that allows an observer to enjoy an enormous field of view. Instead of a lens, the system relies on a diffuser that lies between the object being imaged and the camera sensor. This novel technology could greatly help clinicians to assess diagnostic tissue samples [&he (Read more...)

Credit Card Sized Diagnostic Lab Plugs into Smartphone

Researchers at the University of Cincinnati have developed a tiny portable diagnostic device that can detect the presence of specific pathogens in a saliva sample, and relay the results to a doctor when plugged into a smartphone. The device can potentially diagnose a wide array of diseases, including malaria, HIV and Lyme disease, and could [&helli (Read more...)

Genomic Profiling for Precision Medicine: Interview with David Spetzler, Caris Life Sciences

Caris Life Sciences, a Dallas-based innovator in molecular science focused on fulfilling the promise of precision medicine, has developed the MI Genomic Profiling Similarity (GPS) score to compare the molecular characteristics of specific tumors against those in the Caris database. This allows clinicians to identify the molecular subtype of their p (Read more...)

Device Links Up to 10 Organ Chips to Form Body-on-a-Chip

Researchers at the Harvard Wyss Institute have developed a “body-on-a-chip” consisting of up to 10 organ-on-a-chip devices that are linked together to mimic blood flow between different organ systems. The new system allows for more comprehensive drug testing, enabling researchers to see the effects of a drug on multiple organ systems si (Read more...)

Antimicrobial Layer for Plastic Food Wrap Developed

Bacteria can take a ride and proliferate on the plastic wrap that foods are commonly packaged in. Researchers at Penn State have developed a way to bond a non-toxic transparent antimicrobial material to the ubiquitous polyethylene wrap that meats, vegetables, and mushrooms are sold in. The antimicrobial layer is made of a pullulan-based biopolymer, (Read more...)

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...)

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...)
