With the advent of nanomedicine, the concept of a "magic bullet" to fight cancer is getting closer to reality. Previously an idea straight out of science fiction, researchers around the world are working on perfecting nano- and microscale drug carriers that get injected into the body, transport themselves to the correct target, such as a tumor, and deliver the required dose of a medication or other substance to effectively destroy or repair this target. The controlled drug release required by these systems, however, has proven to be quite a challenging issue. To avoid the side effects of prematurely released toxic cancer drugs on healthy tissues, researchers have designed and fabricated an "active defense" system which could effectively keep the drug entrapped in its carrier in the blood and normal tissues whereas it would allow the explosive drug release under the right physiopathological stimuli once the drug carrier reaches the cancerous tissues.

Bridging the world of atoms and nanoparticles is a class of ultrasmall nanoclusters that contain less than 100 atoms and measure just one or two nanometers. Exploiting the unique properties - optical, magnetic, catalytic - of these nanoclusters in fields such as sensors, microelectronics, biotechnology, energy, and especially catalysis, requires atomically precise fabrication techniques. Making the synthesis of ultrasmall metal nanoclusters much easier than before, researchers have now demonstrated the development of a millifluidic chip as a novel approach for reproducible, high-throughput, and controlled synthesis. Preliminary findings demonstrate that a simple, easy to fabricate millifluidic reactors has the potential for controlled synthesis of nanomaterials.

Controlling the thermal expansion of composites is important for producing nanometer-scale electronic circuits, as well as the next-generation fuel cells and thermoelectric devices. An ability to combine negative thermal expansion materials with 'normal' materials which expand upon heating ensures a reduction in thermal expansion in a composite material.
