Bandage-for-bone

After a bone fracture, the naturally occurring purine nucleoside adenosine floods the injury site, but it does not necessarily remain there to help the bone to heal.  Knowing this, biochemists at Duke University “developed a bone bandage to sequester adenosine molecules to the site of bone injury. They used a polyethylene glycol (PEG) network, functionalized with boronate molecules, which bind adenosine and slowly release it over time.” They found that the bandage accelerated bone repair.  MORE
