Researchers at the National Institute of Standards and Technology (NIST) have developed a prototype bioreactor–a device for culturing cells to create engineered tissues–that both stimulates and evaluates tissue as it grows, mimicking natural processes while eliminating the need to stop periodically to cut up samples for analysis. Tissue created this way might someday be used to replace, for example, damaged or diseased cartilage in the knee and hip. Conventional methods for...

Biomedical engineers at Tufts University's School of Engineering have demonstrated the first all-polymeric bone scaffold material that is fully biodegradable and capable of providing significant mechanical support during repair. The new technology uses micron-sized silk fibers to reinforce a silk matrix, much as steel rebar reinforces concrete. It could improve the way bones and other tissues are repaired following accident or disease. The discovery is reported in the Proceedings of the...

A lot of people were skeptical when two young California-based researchers set out more than a decade ago to create a completely human-derived alternative to the synthetic blood vessels commonly used in dialysis patients. Since then, they've done that and more. "There were a lot of doubts in the field that you could make a blood vessel, which is something that needs to resist pressure constantly, 24-7, without any synthetic materials in it," explains Nicolas L'Heureux, a co-founder and the...

Microalgae are single-cell plants that comprise nature's smallest and most efficient photosynthetic engines: all they need to thrive is water, light, and air. When bred under controlled conditions, their applications range from pharmaceuticals to wastewater treatment to biofuels. Current microalgae breeding methods, however, perform far below the fundamental bounds allowed by the laws of nature. Scientists at Ben-Gurion University of the Negrev in Israel have identified strategies to improve...

Smart, Self-healing Hydrogels Have Possibilities In Medicine, Engineering
2012-03-06 04:22:48

[ Watch the Video ] University of California, San Diego bioengineers have developed a self-healing hydrogel that binds in seconds, as easily as Velcro, and forms a bond strong enough to withstand repeated stretching. The material has numerous potential applications, including medical sutures, targeted drug delivery, industrial sealants and self-healing plastics, a team of UC San Diego Jacobs School of Engineering researchers reported March 5 in the online Early Edition of the Proceedings...

Sandia National Laboratories researchers, using off-the-shelf equipment in a chemistry lab, have been working on ways to improve amputees´ control over prosthetics with direct help from their own nervous systems. Organic materials chemist Shawn Dirk, robotics engineer Steve Buerger and others are creating biocompatible interface scaffolds. The goal is improved prosthetics with flexible nerve-to-nerve or nerve-to-muscle interfaces through which transected nerves can grow, putting small...

The biological scaffold that gives structure to a heart valve after its cellular material has been removed can be freeze-dried and stored for later use as a tissue-engineered replacement valve to treat a failing heart, as described in an article in Tissue Engineering, Part C: Methods, a peer-reviewed journal from Mary Ann Liebert, Inc. (http://www.liebertpub.com). The article is available free online at http://www.liebertpub.com/ten Shangping Wang and colleagues from Leibniz University,...
