New Biomaterial May Replace Arteries, Knee Cartilage
...elopment in the 1950s. Other evidence ofSalubria's biocompatibility
is that it allows new cells to grow on it,effectively making it part of the body, Ku said. Proof-of-concept studies showed Salubria's potential for use in arteryreplacement, including those in the heart because of its mechanical strength.Also...
Rutgers professor details how polymers improve drug delivery and make possible crystal-clear water-based cosmetics
...roperties needed for transporting drugs -- such as biocompatibility
and water solubility -- are needed for beauty aids. If you can use polymers to carry 'greasy' drugs within your body, why not use them to carry 'greasy' dyes or fragrances outside the body?" At present, Uhrich's polymers are targeted at drug...
New application of imaging technique can change how scientists look at proteins
...hed light on a wide range of issues, including the biocompatibility
of medical implants, blood-clotting processes and how cancer spreads. "To a large extent, a protein's structure determines its function," said Viola Vogel, associate professor of bioengineering and director of the UW's Center for Nanotechnology. ...

- the problem of rejection of alien matter by the body - and long-term reliability.The project, unde...
Lab engineers develop microelectronics for artificial retina project
... only flexible, but is a promising material from a biocompatibility
standpoint. Humayun's group implanted three first-generation LLNL devices in a dog's eye to identify needed design and fabrication improvements. Livermore engineers are now working on a second-generation microelectrode array with smaller electrodes ...
Test method provides biocompatibility 'barometer'
... more sensitive and reliable means to evaluate the biocompatibility
of new materials for a wide range of applications ...of biocompatibility. Whereas current means to test biocompatibility
produce a yes/no result that a material is minimally biocompatible or not, the new analysis can tell...
Biocompatibility to widen scope of biomaterial applications
...4--Researchers across the world are working toward biocompatibility
by optimizing interactions that occur between implanted biomaterials and the host living tissue. Overcoming this significant technical challenge is likely to broaden the scope of biomaterials' applications. "Thrombosis involving blood coagulation and...
