Researchers 3D Print Prototype “Bionic Eye”

Researchers at the University of Minnesota have 3D printed a light receptive array, consisting of silver particles and semiconducting polymers, on a glass hemispherical surface. The printed material can convert light to electricity, and the researchers hope that it could one day, with more research, end up serving as a bionic eye. “Bionic eyes are usually … Continue reading

Microscopic Photonic Biosensor Measures Oxygen in Organ-On-Chips

Since oxygen is an essential chemical throughout our body, its presence must therefore be properly mimicked in any realistic organ-on-chip devices. Some cells consume oxygen readily while others not so much, but because this happens on such a small scale, measurement of oxygen consumption on the cellular level has been very difficult. Engineers at North … Continue reading

Mechanoceuticals to Replace Chemical Drugs by Tugging on Cells

Chemicals, delivered in the form of drugs, are the most common way of influencing the activities of cells in our bodies. While great in many ways, there are a myriad of limitations and side effects for clinicians and patients to grapple with. UCLA bioengineers are investigating whether targeted physical manipulation could serve as an additional … Continue reading

Flexible and Conductive Mesh for Implantable and Wearable Bioelectronics

Researchers at the Institute of Basic Science in South Korea have developed a highly stretchable bioelectronic mesh patch which can monitor electrophysiological signals, such as heart muscle electrical activity, and can apply electrical and thermal stimulation for therapeutic purposes. The mesh can be implanted, such as around the heart, or can be worn on the … Continue reading

3D Printed Silicone and Stem Cell Implant to Treat Spinal Cord Injuries

Spinal cord injuries are notorious for the disabilities they cause and for the difficulty of finding a way to fix them. At the University of Minnesota researchers are pointing to a potential solution in the form of 3D printed scaffolds seeded with neuronal stem cells. The team has already created a prototype device, made of … Continue reading

Custom 3D-Printed Microfluidics for Cell-Based Health Research

Researchers at NYU Abu Dhabi (yes, there is such a thing) have developed a method to 3D print functional and inexpensive microfluidic probes for cancer research. The technique could make microfluidics more accessible, allowing researchers to easily design and produce their own devices, and conduct cell-based healthcare research, such as studying cancer cells, more easily. … Continue reading

Biodegradable Paper-Based Batteries May Power Short-Life Medical Implants

The future of advanced implantable medical devices may depend on whether new, biocompatible sources of power can be developed. Batteries that work inside the body and eventually disintegrate may be important for devices that themselves can be resorbed. Researchers at Binghamton University have now developed a fully biodegradable battery that, though not directly designed for … Continue reading

3D-Printed Ceramic Implants Help Regrow Bone

Researchers at NYU have developed 3D-printed ceramic implants that dissolves slowly, allowing bone to grow in their place. The implants can be tailored to mimic the shape of the missing bone, and are chemically-coated to stimulate bone growth. The research team hopes that the technology will be useful for patients with non-healing bone defects. At … Continue reading

Functional Nanofibers Loaded with Antibiotics to Treat Serious Wounds

Researchers at Texas A&M University and Stevens Institute of Technology have been working on developing new materials that could aid clinicians in treating challenging wounds. These polymeric coatings have nano-scale fibers that hold antibiotics and release their cargo when the environment of the wound meets a specific criteria. This makes the material “functional,” and able … Continue reading
