New near-infrared contrast agent reveals bone and breast-cancer-related microcalcifications

Mammography continues to be the method of choice for the early detection of breast cancer. However, because this technique is not as selective or specific as one would wish, and does not deliver reliable results for every level of tissue density, alternatives are being sought.

Secret to bone's strength

Scientists and engineers are eager to understand the secret behind bone's lightweight toughness so they can mimic it in the design of new materials, but previous studies have revealed a number of different strength mechanisms at different scales of focus, rather than a single theory.

Nanosized bioceramic particles could function as efficient gene delivery vehicles with target specificity for the spleen

A detailed comparison of different types of ceramic nanoparticles has found that those made of silica can efficiently transport therapeutic genes to the spleen and trigger a potent immune response capable of attacking tumors.

New contrast agent selectively targets and highlights malignant micro-calcifications in the breast

Harvard Medical School researchers are working on a new, simpler way to distinguish malignant tumors from non-cancerous masses when screening for breast cancer.

Ink-jet printing of bone

A modified ink-jet printer can be used to directly print layer upon layer of artificial bone for quick-fix grafts used in reconstructive surgery.

Ice-templated fabrication shows promise for artificial bone

The next generation of artificial bone may rely on a few secrets from the sea. Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory have harnessed the way seawater freezes to develop a porous, scaffolding-like material that is four times stronger than material currently used in synthetic bone.

Spire Corporation awarded grant to develop nanophase calcium phosphate coatings

Spire Corporation has announced that it has been awarded an SBIR Phase I grant for $156,878 from the National Institute of Dental and Craniofacial Research, National Institutes of Health (NIH), to develop nanophase calcium phosphate coatings loaded with bone morphogenic proteins (BMPs).

Carbon nanotubes may change the way doctors treat broken bones

Scientists have shown for the first time that carbon nanotubes make an ideal scaffold for the growth of bone tissue. The new technique could change the way doctors treat broken bones, allowing them to simply inject a solution of nanotubes into a fracture to promote healing.
