Nanoscience and nanotechnology

This diagram shows one of the core-shell nanoparticles embedded in a host material, as described in a paper in <i>Advanced Materials</i>. The motion of electrons, as shown by brown lines, is bent in such a way that they appear to be unaffected by the presence of the particle, thus allowing them to pass with little resistance.

In this micrograph of an experimental transistor, blue highlighting indicates areas of "strain," where germanium atoms have been forced closer together than they find comfortable. One of the reasons for the transistor's record-setting performance is that the strain has been relaxed in the lateral direction.

Illustration shows the layered structure of the new device, starting with a flexible layer of graphene, a one-atom-thick carbon material. A layer of polymer is bonded to that, and then a layer of zinc-oxide nano wires (shown in magenta), and finally a layer of a material that can extract energy from sunlight, such as quantum dots or a polymer-based material.

These nanoparticles created by MIT engineers can act as synthetic biomarkers for disease. The particles (brown) are coated with peptides (blue) that are cleaved by enzymes (green) found at the disease site. The peptides then accumulate in the urine, where they can be detected using mass spectrometry.

New technology may enable earlier cancer diagnosis

Nanoparticles amplify tumor signals, making them much easier to detect in the urine.
