Stop the bleeding: Nanotech blood platelets

News: Nanomedicine    December 22, 2009
It’s a good example of the spreading use of nanotechnology – artificial blood platelets composed of nanoparticles. Platelets are a small blood-cell type and one of the principle components of blood coagulation, the process used by the body to stop bleeding. Applying nanotechnology to platelets is not an earth-shaking development but it seems a logical [...]

Explaining how a protein can perform multiple roles

Impact: Cell Biology    December 18, 2009
It’s been known for more than a decade that some cell proteins can carry out multiple functions. For example, it was discovered in 1999 that the protein TyrRS (explained shortly) participated not only in the building of enzymes, but also could function to stimulate the growth of blood vessels. Discovering that the same protein could [...]

Nanosensors testing blood for cancer markers

News: Nanomedicine    December 17, 2009
Testing lab samples of blood is one thing; there’s lots of control achieved by isolating components of the blood before testing. Testing whole blood, unfiltered and with all components in their usual mix, is another thing. The thing is; testing whole blood is what’s required in the real world. Whole blood is complicated by the [...]
