Silicon nanocoils catalyzed by Co nanoparticles

Much work has been done to create nanomaterials through various synthetic methods. However, it is still difficult to characterize the structure of nanomaterials and control their chemical properties. Our approach is to create useful nanomaterials with which we can make other nanomaterials such as X-ray catalysts or X-ray driven nanomachines. In one example, we used cobalt nanoparticles to produce both straight and coiled silica nanowires. We contribute the cause for the formation of nanocoils to the existence of asymmetric cobalt nanoparticles. In another example, we are creating complex nanomachines to enhance the effect of X-rays.
