Self-assembling nano-fiber gel delivers high concentrations of clinically approved drugs
Two teams of scientists from Harvard-MIT Division of Health Science and Technology (HST) at Brigham and Women's Hospital have developed a new self-assembling hydrogel drug delivery system that is biocompatible, efficient at drug release, and easy to tailor. view more (2008-10-22)
Hydrogels provide scaffolding for growth of bone cells
Hyaluronic hydrogels developed by Carnegie Mellon University researchers may provide a suitable scaffolding to enable bone regeneration. The hydrogels, created by Newell Washburn, Krzysztof Matyjaszewski and Jeffrey Hollinger, have proven to encourage the growth of preosteoblast cells, cells that... view more (2008-08-18)
'Smart' materials get smarter with ability to better control shape and size
A dynamic way to alter the shape and size of microscopic three-dimensional structures built out of proteins has been developed by biological chemist Jason Shear and his former graduate student Bryan Kaehr at The University of Texas at Austin. view more (2008-07-07)
Joint research: Probing the mysteries of a surprisingly tough hydrogel
Some 46 million people suffer from arthritis in the United States alone. The worst cases require painful surgeries to drill holes in and reinforce joints. view more (2008-03-12)
UD scientists invent novel hydrogels for repairing, regenerating human tissue
University of Delaware scientists have invented a novel biomaterial with surprising antibacterial properties that can be injected as a low-viscosity gel into a wound where it rigidifies nearly on contact--opening the door to the possibility of delivering a targeted payload of cells and antibiotics... view more (2007-07-19)
MIT particles pave way for new bedside diagnostics
MIT researchers have created an inexpensive method to screen for millions of different biomolecules (DNA, proteins, etc.) in a single sample-a technology that could make possible the development of low-cost clinical bedside diagnostics. view more (2007-03-09)
A new approach to growing heart muscle
It looks, contracts and responds almost like natural heart muscle - even though it was grown in the lab. And it brings scientists another step closer to the goal of creating replacement parts for damaged human hearts, or eventually growing an entirely new heart from just a spoonful of loose heart... view more (2006-12-08)
An artificial cornea is in sight, thanks to biomimetic hydrogels
If eyes are "the windows of the soul," corneas are the panes in those windows. They shield the eye from dust and germs. They also act as the eye's outermost lens, contributing up to 75 percent of the eye's focusing power. view more (2006-09-12)
Soft materials buckle up for measurement
Buckling under pressure can be a good thing, say materials scientists at the National Institute of Standards and Technology (NIST). view more (2006-06-28)
Getting ACL tears to heal themselves
A surgeon at Children's Hospital Boston may have found a better way to repair tears to the anterior cruciate ligament (ACL), a knee injury suffered by more than 100,000 Americans each year, particularly teenage girls. view more (2006-03-29)
Bioengineers create stable networks of blood vessels
Yale biomedical engineers have created an implantable system that can form and stabilize a functional network of fine blood vessels critical for supporting tissues in the body, according to a report in the Proceedings of the National Academy of Sciences. view more (2006-03-01)
Reversible Microlenses to Speed Chemical Detection
The microlenses make use of the antibody-antigen binding, the same process used by the human immune system, to detect biological or chemical agents. view more (2006-02-14)
Hopkins study shows 30-day soft contact lenses pose very small risk of vision loss
A team of researchers led by the Johns Hopkins Wilmer Eye Institute have determined that the corneal infection rate associated with the use of 30-day -extended-wear contact lenses made from silicone hydrogel is comparable to that previously reported for older lens types worn for fewer consecutive... view more (2005-12-02)
Research warns against sleeping in contact lenses
Sleeping in contact lenses can lead to an increased risk of severe eye infection, new research suggests. But new generation contact lenses, the investigation reveals, perform better in this regard than their predecessors. view more (2005-03-21)
New gel pill could mean an end to injections
Scientists in India have developed a new gel that is taken orally and is capable of delivering drugs to manage diseases often requiring an injection. The research, published in the journal Polymer International, suggests the gel could offer a painless way of treating diabetes, ulcerative colitis,... view more (2004-09-16)
Millions turn a blind eye to dangerous driving
As many as 2.5 million adults in the UK are putting themselves and others at risk by deliberately ignoring the fact that they have bad eyesight. Most do so largely because of outdated information about contact lenses and preconceived ideas about glasses, a study by Dr June McNicholas, senior... view more (2003-08-08)
Contact lenses inside the eyes
INASMET Foundation, a member of the TECNALIA Corporation from the Basque Country, is currently carrying out research on intraocular lenses. In fact, INASMET presented two projects at the 17th European Congress on Biomaterials held in Barcelona. Apart from publishing the results of a comparative... view more (2003-01-03)
Insulin Pills
The issue of insulin-dependent diabetes has long been discussed. No wonder, as the problem concerns more than 5% of the world population. However, despite the enormous efforts and funds spent on its solution, the scientists so far have failed to replace the injections with pills. The difficulty is... view more (2002-02-26)
A model of Pancreas based on the insulin extracting gel-polymer system
If the blood glucose overcontents (permissible content is 0.8-1 mg/ml), the pancreas be-gins to extract some inculin by which an unnecessary glucose is eliminated from blood and is assimilated by tissues. view more (1999-08-20)
