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...)

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...)

Breath Analyzer for Acute Respiratory Distress Syndrome

Acute respiratory distress syndrome (ARDS) is a condition in which fluid leaks into the lungs and builds up in the alveoli within. It is a rapidly progressive condition that often leads to terminal consequences, yet it can be difficult to diagnose and monitor. Now, researchers at University of Michigan have developed a portable device that [&hellip (Read more...)

Using Microparticles to Measure Oxygen in Tissues

The field of tissue engineering is rapidly progressing, in large part thanks to hydrogel scaffolds that provide a comfortable home for new cells. A major issue that researchers bump against is tracking how well oxygen reaches freshly grown cells within such scaffolds, which can indicate how well the new cells are generally functioning. Now, researc (Read more...)

Blood Flow Measurement Using Tiny LED Catheter

Measuring blood flow is important during a variety of surgical procedures, as well as in intensive care settings. Typically, this is performed intermittently, so there’s not a lot of temporal detail in the readings. Now, a team of researchers at Flinders University in Australia has developed a proof-of-concept prototype vascular catheter that (Read more...)

Tiny Nanowire Probes Measure Intracellular Electrical Activity

Researchers at the University of Surrey and Harvard University have developed tiny nanoprobes that can measure electrical signals inside cells, such as neurons and cardiac cells. Unlike previous technology for intracellular electrophysiology, the nanoprobes cause minimal destruction to the cells, and could pave the way for human-machine interfaces (Read more...)

Microfluidic Chip Allows Embryonic Stem Cells to Differentiate

Complex multicellular organisms, such as ourselves, start out from stem cells that differentiate into different kinds of cells. This process is controlled by groups of cells that secrete special signaling molecules called morphogens, which guide nearby stem cells to turn into the kinds of cells that should be located in that region. This is an [&he (Read more...)

BIOTRONIK Releases BIOMONITOR III Injectable Cardiac Monitor

BIOTRONIK is releasing a new version of its popular BIOMONITOR injectable cardiac monitor. The BIOMONITOR III is less than half the size of the BIOMONITOR 2, while offering much clearer signal quality. It is designed to be injected under the skin, where it can reside for weeks while continuously monitoring and recording the patient’s electric (Read more...)
