Semiconductor quantum dots are fascinating objects, since, in some respect, they can be regarded as artificial atoms [1]. Figure 5.1 shows a very schematic comparison of a real three–dimensional atom and a disc–shaped quantum dot. The structure of real atoms is three–dimensional, while most of the artificial quantum dots can be regarded as large Q2D atoms, since the lateral dimensions are in most cases much larger than the vertical extension. Of course, a crucial difference between the two systems is the shape of the confining potentials, which, for real atoms is essentially the Coulomb potential of the nucleus, and, for quantum–dot atoms in some approximation a two–dimensional parabolic potential.

In conclusion, because of the responses observed in phase I, II and III trials with angiogenesis inhibitors in combination with other biological agents or classic chemotherapy, there is no longer doubt that anti-angiogenic agents have become part of anticancer therapy in general. In the coming years, we should further explore the treatment strategies in which anti-angiogenic agents will add to a prolonged survival and an increase in the cure rate of cancer. In our opinion, the contribution of these agents will be tremendous.
