Abstract
A brief personal account of the relation of the author with Professor Gordon Stone is described. Then the two parts of the scientific presentation of the symposium talk is given. The first part shows that there are two classes of two-electron three-centre bonds. And the manner in which the se two types of bonds differ in their interaction with each other is shown. For example in the Class II 2e-3c bond the central bridging atom formally contributes two electrons to each of the other two atoms, in terms of electron counting considerations. The second part describes how carbon nanotubes, decorated with sugar molecules on the outside and filled with radioactive iodine, sealed in the interior of the SWNTs can be delivered selectively to the lungs of a mouse. The radio nuclei are selectively located in exceptionally high concentrations and this has implications for applications in radio surgery.
