How 3D printed cells on the skin could enable wound healing

Researchers at the University of Minnesota are 3D printing electronics and cells directly on the skin that could create new methods for wound healing and enable biological agent detection. The Minnesota researchers used a customized, low-cost 3D printer to print electronics on a human hand. They’ve also successfully printed biological cells on a sin wound of

This augmented reality system projects medical images on the body

Augmented reality is helping doctors visualize what’s inside the body without having to pick up a scalpel, thanks to a new system from the University of Alberta. The system ProjectDR projects medical images like CT scans and MRI data directly onto a patient’s body in a way that moves with the body. “We wanted to

Nelson Labs expands lab operations at Illinois facility

Nelson Labs recently announced that it has invested in expanding its operations and service capabilities at its Itasca, Ill. facility. The investment will offer upgrades to the laboratory facilities, in addition to a 10,000 sq. ft building expansion and renovated lab space. The upgrades will include a BI sterility suite to support EO sterilization validations

DARPA is developing nonsurgical neural interfaces to expand neurotechnology

Researchers from the Defense Advanced Research Projects Agency (DARPA) have recently started a new program called Next-Generation Nonsurgical Neurotechnology to develop a non-invasive brain-system communications system to allow patients to communicate with devices using their brain. State-of-the-art brain communications systems that exist today are traditionally invasive, but allow for precise, high-quality connections to specific neurons

Turns out graphene can fight bacteria on implants

Graphene flakes that are arranged like spikes can kill bacteria and stop infections during implant surgery procedures, according to new research from Chalmers University of Technology in Göteborg, Sweden. Bacteria moves around the body in fluids like blood looking for an area to stick to. Once they find a place, the bacteria starts to grow

Paper-folding art is the inspiration behind these adhesives

A paper-folding art known as kirigami is the inspiration behind a new adhesive film for bandages that don’t usually stick to mobile joints like the knees and elbows. Massachusetts Institute of Technology researchers have developed a thin, lightweight and rubber-like adhesive film that sticks to highly deformable regions of the body. The kirigami-inspired film has

How a new MRI technique is improving patient comfort

Researchers at Cedars-Sinai in Los Angeles have created a new technique for administering magnetic resonance imaging tests that helps patients be more comfortable and decreases testing time while increasing accuracy and reliability. The new test is called MR Multitasking and tackles a common problem cardiologists face which is getting a still image when the heart

This sensor attaches to the tooth and tracks dietary intake

Scientists in Massachusetts have developed a tiny sensor that fits on the surface of a tooth and tracks dietary intake. Tuft University School of Engineering researchers created a sensor that communicates wirelessly with a mobile device. It transmits information regarding glucose, salt and alcohol intake, which the researchers suggest could help detect and record a

This visor-like device could be a defibrillator for stroke

A portable, visor-like device has shown potential for detecting emergent large-vessel occlusion with 92% accuracy in patients who may have had a stroke. The researchers suggest that the diagnostic device could be readily accessible to emergency personnel and in public spaces in the same way a defibrillator is available for treating heart attacks. Researchers and

This fluorescent dye could create clearer biological imaging

Massachusetts researchers have repurposed a commercially-available dye that has been around since the 1950s to make short-wave infrared easily available for clearer imaging. Fluorescence imaging is often used to visualize biological tissues or blood vessels during reconstructive surgery to see if vessels are connected properly. Currently, researchers use a dye that runs at the near-infrared

This patented 3D printing method could boost medical device innovation

Michael McAlpine, a 3D printing pioneer at the University of Minnesota, suspects that a method he helped invent to print semiconductors could help boost innovation in the medical device field and elsewhere. The U.S. Patent Office in February issued a patent for “3D printed active electronic materials and devices.” The patent covers work that McAlpine, a

DARPA is developing a human memory prosthesis: Here’s how

The Defense Advanced Research Projects Agency (DARPA) has successfully created what it is calling a human memory prosthesis, a system with electrodes implanted in the brain that restores memory function using a person’s own neural codes. DARPA has been working on restoring normal memory function in military personnel since 2013 in a program known as

These sweat patches can tell when you are tired, among other things

A new organization called NextFlex has teamed up with GE Global Research and is looking to scale up hybrid, flexible electronics called sweat patches that measure fatigue in pilots, elite athletes and other potential medical users — all by analyzing their sweat. NextFlex is a young entity and an unusual one. Founded in 2015, the

This new technique could make TAVR more available

A novel technique could prevent coronary artery obstruction — a rare but often fatal complication related to transcatheter aortic valve replacement (TAVR), according to the National Institutes of Health researchers who created it. The researchers at NIH’s National, Heart, Lung, and Blood Institute are calling the procedure Bioprosthetic Aortic Scallop Intentional Laceration to prevent Iatrogenic Coronary Artery obstruction (BASILICA).

Charles River Laboratories completes MPI Research buy
