Human genetic material is stored at a laboratory in Munich May 23, 2011. On May 25, 2011 the ethic commission of the German lower house of parliament (Bundestag) will discuss about alternative proposals for a new law on the use of preimplantation genetic diagnosis (PGD). Preimplantation genetic diagnosis (Praeimplantationsdiagnostik) is a technique used to identify genetic defects in embryos created through in vitro fertilization (IVF) before pregnancy, which is banned by German legislation.

Multimodal nanosensors (1) are engineered to target and respond to hallmarks in the tumor microenvironment. The nanosensors provide both a noninvasive urinary monitoring tool (2) and an on-demand medical imaging agent (3) to localize tumor metastasis and assess response to therapy.
