Cells selectively absorb short nanotubes
... optical and electronic properties, but safety and biocompatibility remain an open question. "Published data citing in vitro (outside the body) toxicity are particularly inconsistent and widely disputed," writes biomaterials scientist Matthew Becker and his NIST colleagues. Public concerns surrounding the environm...Widely used iron nanoparticles exhibit toxic effects on neuronal cells
...ence leads us to conclude that any analysis of the biocompatibility of nanoparticles should include not just a toxicological study of the component parts," said Pisanic, "but also an examination of the total structure as a whole."...An artificial cornea is in sight, thanks to biomimetic hydrogels
... The researchers are now testing the material for biocompatibility in animal models. Animals have tolerated artificial corneas with no problems in trials as long as eight weeks, Ta says. The material remains perfectly clear, he says. Longer trials are a next step. The current source of tissue for corneal transplan...New methods for screening nanoparticles
...onal factors, are all taken into account to assess biocompatibility and assure safety," she added. "Still, our methods give us a way to screen-out those nanoparticles that shouldn't even make it that far, or identify ways to improve them first." ...Virginia Tech scientists develop process for creating biocompatible fibers
...y for horses. "We have not yet tested the specific biocompatibility (cytotoxicity) of our fibers, but we have not changed the chemical structure of the phospholipids."...Magnetic nanoparticles assembled into long chains
...ir paper are now developing methods to improve the biocompatibility of these magnetic nanoparticles.......er their alignment, while other groups improve the biocompatibility of nanotubes by increasing their solubility in water. "Researchers today are realizing that mechanical mimicry of any material alone cannot succeed in duplicating the intricacies of the human body," Haddon says. "Interactions of these artificial mate...
