Multi-Organ Lab-on-a-Chip for Cancer Drug Testing

Researchers at Hesperos, Inc., a biotech firm based in Florida, have collaborated with Roche and the University of Central Florida to develop a multi-organ lab-on-a-chip system for drug testing. The device includes human organ-derived tissue constructs that allow for the efficacy and side-effects of anti-cancer drugs in various organs to be tested (Read more...)

Ultra-Thin Probe Assesses Tissues Deep Within Lungs

Assessing the health of tissues deep inside the body is a major need and challenge in medicine. Imaging modalities such as MRI, CT, and ultrasound provide very little information about the composition and environment of tissues being examined. Now, researchers at the University of Edinburgh, Heriot-Watt University, and Bath University, all in the U (Read more...)

Molecular Motors Drill Through Cancer Cells

A couple of years ago a team of U.S. and U.K. scientists came up with a way of making molecular motors that can drill through cancer cells, destroying them in the process. The researchers, from Rice University, Durham University, and North Carolina State University, used an ultraviolet (UV) light source to energize these motors, but […]

New Microfluidic Chip to Accurately Model Blood-Brain Barrier

Researchers from the Wyss Institute at Harvard University have developed a new microfluidic lab-on-a-chip device that aims to more accurately model the complex biological properties of the blood-brain barrier (BBB). Their work, recently published in Nature Communications, demonstrates the device is able to mimic the highly selective drug and antibo (Read more...)

Microfluidic Impedance Sensor Can Monitor Sickle Cell Disease

Researchers at Florida Atlantic University have developed a microfluidic chip that can rapidly assess blood samples from sickle cell disease patients to help monitor the disease. The technique is much faster and more convenient than traditional optical microscopy assessments. Sickle cell disease affects approximately 100,000 individuals in the U.S. (Read more...)

Octopus-Inspired Wearable Biosensor Sticks to Wet and Dry Skin

Researchers from Daegu Gyeongbuk Institute of Science and Technology (DGIST) in South Korea have developed a new waterproof, wearable biosensor that can stick to the skin in a unique way. Their work, recently published in ACS Applied Materials and Interfaces, demonstrates the biosensor adheres to the skin in wet and dry conditions and can monitor [ (Read more...)

Liquid Biopsy for Monitoring Transplanted Stem Cells

Researchers from the University of Maryland, University of Pennsylvania, and Emory University have demonstrated that a blood test can be used to track the efficacy of transplanted stem cells. They analyzed tiny cellular components called exosomes that were secreted from transplanted stem cells. “Exosomes contain the signals of the cells they& (Read more...)

Simple Test Uses UV Light to Measure Stress Levels

Researchers at the University of Cincinnati have developed a simple biosensor that uses UV light to measure levels of stress hormones in saliva, blood, urine, or sweat. The researchers hope that the test will eventually be available as an at-home test kit that people can use to assess their stress. Other applications include monitoring people [&hel (Read more...)
