Sacrificial Ink Writing Technique for 3D Printed Organs

Researchers at Harvard have developed a way to 3D print vascular channels in large matrices composed of stem cell-derived organ building blocks. The technique could pave the way for 3D-printed organs. Creating human organs using 3D printing would help to address the current shortfall in available transplants. However, to date, this has proved to be (Read more...)

Multi-Sensing Glove Makes Prosthetic Hands More Real

Engineers from Purdue University, University of Georgia, and University of Texas have combined forces to develop a glove that can be put over existing prosthetic hands to give them a more life-like feel and the ability to sense a variety of parameters. The glove is intended to improve a user’s ability to interact with others. […]

Nanoscale Light Manipulation for Detection of Tiny Pathogens

Viruses are so small that to be able to detect them using light you need instruments that work on the nanoscale. Sensors so perfect are very hard to make, as most manufacturing processes disrupt nanoscale structures. Now, a team at Purdue University has developed a way to combine 3D plasmonic nanoarrays, special light manipulation devices, [&hellip (Read more...)

High-Performance Handheld Ultrasound Based on Piezoelectric Micromachined Ultrasonic Transducers

The company EXO Imaging out of Redwood City, CA recently emerged from stealth mode to announce the development of a novel technology called Piezoelectric Micromachined Ultrasonic Transducers (pMUT) for ultrasound imaging. EXO Imaging is bringing together advances in micromachined materials and artificial intelligence to enhance both the ultrasound (Read more...)

Swiss Scientists Print World’s Smallest Stent

In rare cases, some children, often still in the womb, develop urethral strictures that make it difficult or impossible to empty the bladder. Typically, a surgical procedure is performed to remove the narrowed section of the urethra, with the open ends being sewed together. This is traumatic for the children and can be difficult for […]

Biomaterial Tricks Immune System to Grow New Blood Vessels

Researchers from Harvard’s Wyss Institute have developed a new biomaterial that can activate T cells to promote vascularization of ischemic tissues. Their work demonstrates that the biomaterial results in local blood vessel development, increased perfusion, and new muscle growth after ischemia. Various compounds have been tested to try to imp (Read more...)

Magnetically Controlled Soft Robots to Operate on Human Body

Although a myriad of robots is already used in a variety of industries, including medicine, they’re almost exclusively rigid devices using conventional mechanics. To best work with the pliability of the human body, it may be advantageous for medical robots to be soft and not include gears, motors, and metal cables. Researchers at North Caroli (Read more...)

Ultrasound System to Charge Medical Implants

Batteries power most electric medical implants. Pacemakers, for example, use the same battery for years without recharging, but eventually have to be replaced once the charge starts to run out. There have been numerous attempts to create technology to generate electricity from within the body to power these devices. These have resulted in rather mo (Read more...)

LipoGlo Makes Bad Cholesterol Glow Inside Zebrafish

So-called “bad cholesterol” is a molecular complex of fat and protein. Specifically, the protein is Apolipoprotein-B, or ApoB, and the fat is cholesterol. While ApoB helps fat molecules to move around the blood vasculature, it is also what makes cholesterol stick to vessel walls, forming dangerous plaques that are one of the main causes (Read more...)

Imperceptible Wearable Electronics Only Microns Thin

When we think of wearable electronics, devices such as smartwatches, chest-strap heart monitors, and wrist-worn activity trackers come to mind. In the future, and one that is seemingly not that far away, wearables may look like tattoos that are only microns thick. That may be thanks to researchers from the University of Houston, University of [&hel (Read more...)

3D Printed Cardiac Components

Researchers at Carnegie Mellon University have developed a method to 3D print collagen and cells to form organ components, potentially paving the way for full organ printing in the future. The technique, called Freeform Reversible Embedding of Suspended Hydrogels (FRESH), involves printing collagen layer-by-layer in a bath of support gel, which all (Read more...)

Tiny Robots Aim to Work Inside Our Bodies

If we’re to have robots that work inside our bodies to find and cure diseases, they must be very small. To help make the dreams of futurists a reality, researchers at Georgia Tech have now created a robot that weighs only five milligrams and is no taller than the side of a US penny. The […]

Artificial Protein Switch for Smart Cell Therapies

Researchers from University of California, San Francisco and the University of Washington have developed a new artificial protein switch, dubbed LOCKR. Their work demonstrates that the new switch can be used to control many intracellular processes, including mediating molecular traffic inside a cell, degrading specific proteins, and causing a cell (Read more...)
