Material Made from DNA Undergoes Metabolism, Powers Itself

Scientist at Cornell University have developed a remarkable new material, which is made out of DNA and which undergoes metabolism. One of the crucial aspects of life is metabolic activity, which essentially means that large molecules are broken down and small molecules are used to build larger ones. The dynamic material that the Cornell team [&hell (Read more...)

Engineered Matrix to Improve T Cell Immunotherapy

Researchers from Johns Hopkins University have developed an “artificial lymph node” to help multiply antigen-specific T cells to fight cancer. They used a hydrogel that contains immunostimulatory antigen-presenting nanoparticles to encourage T cells to proliferate, and have increased activity against specific antigens. Current T-cell ba (Read more...)

Nanocomposite Heart Valve to Replace Animal-Derived Devices

Researchers at the University of British Columbia (UBC) have developed a nanocomposite biomaterial heart valve that could provide an alternative to the animal valves that are currently used as heart valve replacements. Moreover, the nanocomposite valves can be delivered to the heart through a transcatheter, allowing for minimally invasive placement (Read more...)

Contraceptive Jewelry from Georgia Tech

Contraceptives are very effective, as long as they’re administered on a tight schedule. All too often many women forget or ignore to take the pill, leading to unwanted surprises. Researchers at Georgia Tech, taking into account today’s fashion of wearing unusual jewelry, have developed an earring, necklace, ring, and a wrist watch, each (Read more...)

CRISPR-Chip Can Detect Genetic Mutations Within Minutes

Researchers at the University of California, Berkeley and the Keck Graduate Institute of The Claremont Colleges have developed a hand-held device that can detect genetic mutations, such as those causing genetic diseases or affecting how people respond to certain drugs, in just minutes. The device employs a combination of CRISPR and graphene transis (Read more...)

Fingertip Elasticity Probe Helps Spot Breast Tumors

Our fingertips are incredibly sensitive biomechanical devices. They’re regularly used by physicians to feel out tumors during biopsy or excision surgeries. While reasonably effective, too many patients return for repeat procedures to remove missed bits of target lesions. Researchers at University of Western Australia have been working on (Read more...)

Interview with Tom Reeves, CEO of Interface Biologics

Interface Biologics Inc (IBI) is a company from Toronto, Ontario, Canada that develops medtech and pharmaceutical materials. Their surface modification technology is called Endexo, which involves fluorine-based additives that migrate to a material’s surface during polymerization. This non-stick fluorination prevents platelets and bacteria fro (Read more...)

Injectable Bone Scaffolding Made of Plant Cellulose

The majority of bone implants, cements, and grafts are hard objects that don’t always work well in filling the space they’re supposed to inhabit. Soft objects can gently expand and relocate their mass evenly over a volume, and they tent to be less dense so as to leave room for cells to make home inside […]

Bioreactors Inside Body Grow New Bones for Transplantation

Injuries and disease often necessitate putting something in place of where natural bone is. While there are custom-made artificial orthopedic implants and native bone grafts, researchers from Rice University have now shown a new and better way. The team printed in 3D a bioreactor mold within which new bone can grow. It is made to be […]
