The invention relates to a method for preparing a bisphosphonate co- valently bonded to a nanostructure. This invention also relates to a bisphosphonate having incorporated therein a radioisotope selected from 32p or 33P, preferably 33p, wherein the bisphosphonate is cova- lently bonded to a nanostructure directly or by way of a linker, and to the use thereof in a method of treating calcific tumours in a patient. (Formula (I)):
