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...)

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...)

New Bioink for 3D Printing and Protein Therapy

Researchers at Texas A&M University have developed a 3D-printable hydrogel bioink containing mineral nanoparticles that can deliver protein therapeutics to control cell behavior. The material does not provoke the immune system and the researchers hope that it could be useful in replacing damaged tissues for regenerative medicine. 3D printing is (Read more...)

Patches Made of Heart Tissue Going to Clinical Trials

Stem cell therapies to heal damaged hearts have proven to be lacking so far, probably because simply injecting new cells into afflicted regions isn’t enough. Researchers from Imperial College London have now created patches made of cardiac tissue to sew over damaged areas of the heart. These patches, which can beat on their own to […]

3D Printed ELISA Pipette Tips for Low Cost Medical Testing

Researchers at the University of Connecticut have developed a 3D printed enzyme-linked immunosorbent assay (ELISA) device, which fits onto a normal pipette and substantially reduces the time and cost of this common medical test. The device could allow for medical testing in remote or low-resource regions, where such tests would otherwise be unavail (Read more...)

Microscopic Graphene Flakes to Stop Epileptic Seizures

During epileptic seizures, the brain’s excitatory neurons go haywire, generating extreme amounts of electric activity. There are already electronic devices available that help to prevent and mitigate seizures, but so far they’re only effective in some patients while having all the downsides of a serious implantation. A team of European (Read more...)

Synthetic Proteins Designed to Halt Growth of Cancers

Stanford University scientists have developed a novel approach to halting the growth of cancer cells while preserving normal function in healthy cells. The research was published in journal Science, and though it was so far conducted only on groups of cancer cells outside a body, the findings are incredibly promising. The new approach focuses on [& (Read more...)

Intestine Chip to Study Human-Microbiome Interactions

Researchers at the Harvard Wyss Institute have developed a microfluidic chip that allows bacteria and human epithelial cells to be co-cultured. The device will allow researchers to study how the gut and bacteria interact, helping them to identify the role of the microbiome in health and disease. With reported involvement in a huge array of [&hellip (Read more...)

Scorpion Protein Used to Help Visualize Brain Tumors

Clinicians at the Cedars-Sinai Medical Institute, along with scientists at Blaze Bioscience, Inc., have developed a new way to visualize brain tumors. The new imaging technique utilizes a special, high-sensitivity near-infrared camera developed at Cedars-Sinai, along with tozuleristide, or BLZ-100, the tumor-cell binding imaging agent developed by (Read more...)

Cardiovascular Patch to Limit Damage After Heart Attack

Researchers from Brown University have utilized computational models to design a new viscoelastic patch to reduce damage to heart tissue after a heart attack. They utilized a special blend of starch to help provide mechanical support to the heart tissue, which typically stretches after heart attack and results in poor heart function. “Part of (Read more...)
