"Professor Wark added: 'What is particularly remarkable about our experiment is that we have turned ordinary aluminium into this exotic new material in a single step by using this very powerful laser. For a brief period the sample looks and behaves in every way like a new form of matter. In certain respects, the way it reacts is as though we had changed every aluminium atom into silicon: it’s almost as surprising as finding that you can turn lead into gold with light!'"
"Nanodiamonds have many advantages for biomedical applications. The large surface area allows a large amount of therapeutic to be loaded onto the particles. They can be functionalized with nearly any type of therapeutic, including small molecules, proteins and antibodies. They can be suspended easily in water, an important property in biomedicine. The nanodiamonds, each being four to six nanometers in diameter, are minimally invasive to cells, biocompatible and do not cause inflammation, a serious complication. And they are very scalable and can be produced in large quantities in uniform sizes.
By harnessing the unique surface properties of the nanodiamonds, Ho and his colleagues have demonstrated that the nanodiamonds serve as platforms that can successfully bind, deliver and release several classes of therapeutics, which could impact a broad range of medical needs."
