Small particles of gold could form the basis of a new treatment for Alzheimer's, according to research carried out in Spain and Chile. Researchers attached gold nano-particles to beta amyloid fibrils in test tubes and exposed them to low levels of microwave radiation. They found that the fibrils dissolved and did not re-aggregate. Whether the treatment would prove too expensive for recommendation by NICE remains unclear (Nano Letters; 2006; 6 (1); 110-5).
