DOUGLAS FARMER, SENIOR EDITOR [email protected]A group of researchers has demonstrated that assembling a network of tiny, approximately 1.5-mm3 blocks with the aid of optical technology can be an effective way to accelerate healing in tissue and bone. Using Lego blocks as inspiration, they even learned that filling these blocks with different materials could direct specific healing to where it was needed most. The blocks were essentially used as a scaffolding in an experiment with laboratory rats. The research was led by Luiz Bertassoni, an associate professor in biomedical engineering in the Oregon Health & Science University...Read full articleRelated content from Photonics MediaArticlesDiode Demonstration Establishes Efficient Route to Sterile SettingsSince their introduction in the 1960s, laser diodes have been developed and commercialized for a number of applications with wavelengths ranging from infrared to blue-violet.
