Using a 3D bioprinter, a group of engineers at Chalmers University of Technology have created objects made entirely by cellulose. The additive manufacturing process could be used to build patient-specific implants, new sensors, and wound dressings that communicate with healthcare workers.

A new study from Montreal's Research Institute of the McGill University Health Centre (RI-MUHC) found that a commonly used plasticizer known as DINCH exerts biological effects on the metabolic processes of mammals. DINCH is found in products that come into close contact with humans, such as...

The electromagnetic radiation caused by wireless technology can interfere with electronic medical equipment and lead to serious clinical consequences for patients. New research from Concordia University helps to define safety parameters for health-care workers carrying Wi-Fi...

By integrating two common imaging techniques, experts from Spectrum Health Helen DeVos Children’s Hospital have produced a three-dimensional anatomic model of a patient’s heart. The hybrid prototype could provide better diagnostic capability and improved interventional and surgical...

Using nanowires, Purdue University researchers has created a new implantable drug-delivery system that can be wirelessly controlled. The nanowires respond to an electromagnetic field generated by a separate device, which can be used to release a pre-loaded drug. The engineering team says that...

Changchun "Chad" Zeng from Florida State University's High Performance Materials Institute (HPMI) has developed a new auxetic foam. Prosthetic socks made from the foam will help amputees adjust prosthetic devices to their specific limb shape and volume.

Using a 3D printer and detailed computer simulations, researchers from the Massachusetts Institute of Technology produced soft material with controllable surface textures that can be varied by squeezing. By creating smooth, ridged, or custom-patterned surfaces at will, the technique will allow...

Researchers at the University of Illinois at Urbana-Champaign have created thin, flexible electronic devices that efficiently harvest the mechanical energy from natural motions of the human body. In addition to advances in materials processing to enable fabrication of these thin film devices, accurate analytical models...

A team of scientists from the University of Twente in The Netherlands has discovered a way to 3D print structures of copper and gold, by stacking microscopically small metal droplets. These droplets are made by melting a thin metal film using a pulsed laser. They say that this technology would allow...

A robotic glove built by a team of engineers at the Wyss Institute for Biologically Inspired Engineering and Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) could assist patients suffering from loss of hand motor control.

An injectable hydrogel from the UCLA Henry Samueli School of Engineering and Applied Science helps skin wounds heal more quickly. An instant scaffold created by the material allows new tissue to latch on and grow within the cavities formed between linked spheres of gel.

University of Illinois engineers have created heat-activated self-destructing electronic devices. A radio-controlled trigger remotely prompts the process on demand.

Columbia Engineering researchers have designed a new technique to build a single-molecule diode. Their results achieved rectification ratios as high as 250, fifty times higher than earlier designs.

Through a clinical collaboration between Caltech, Keck Medicine of USC, and Rancho Los Amigos National Rehabilitation Center, a man paralyzed from the neck down can use a robotic arm to perform a fluid hand-shaking gesture, drink a beverage, and even play "rock, paper, scissors." The...

A microfluidic device called the Cluster-Chip, developed by a team of scientists at Massachusetts General Hospital, is the first designed specifically to capture clusters of two or more rare circulating tumor cells (CTCs), rather than single cells. The ability to isolate intact clusters, they say, can enable...

Researchers at Michigan Technological University, Houghton, recently acquired a 3D bioprinter with which they plan to “print” synthesized nerve tissue. The key, they say, is developing the right “bioink” or printable tissue. One of the team member’s research on cellulose nanocrystals as...

Geometrically encoded magnetic sensors (GEMs), developed by researchers from National Institute of Standards and Technology (NIST) and the National Institutes of Health (NIH), react to local biochemical conditions by changing their shape and response to radio frequencies.

An adhesive technology helps to bond human tissue in wet or moist conditions. The chemistry is based on the environmentally-friendly adhesive qualities of mussels and other shellfish.

A new algorithm allows a person to use his or her thoughts to grasp a bottle or other object. The non-invasive brain monitoring technique, developed by University of Houston researchers, will help the team understand the neuroscience behind the action of grasping.

Rice University graduate students and researchers have made nanowires between 6 and 16 nanometers wide. The wires are made from a variety of materials, including silicon, silicon dioxide, gold, chromium, tungsten, titanium, titanium dioxide, and aluminum. The development of sub-10-nanometer sizes shows...

A Massachusetts Institute of Technology team has developed a new, ultrasensitive magnetic-field detector. The device could lead to miniaturized, battery-powered devices for medical imaging.

A device developed by Massachusetts General Hospital investigators provides rapid, accurate molecular diagnosis of tumors and other diseases. The smartphone-based technology collects detailed microscopic images for digital analysis of the molecular composition of cells and tissues.
