The building blocks of healthy collagen, above, begin with one-nanometer-sized amino acids, which form the universal 300-nanometer tropocollagen strands. Fibrils composed of those strands, in turn, make up the steel-cable-like collagen fibers.

This micropump developed by MIT researchers allows high speed flows through microchannels with an input of only a few volts of electricity, making it possible to create portable "lab on a chip" devices.
The three-dimensional, alternating current electro-osmotic pump consists of interdigitated stepped gold microelectrodes on a glass substrate.

MIT research scientist Rutledge Ellis-Behnke, left, and Professor Gerald Schneider bracket a monitor showing a transected liver after it has been treated with a liquid solution containing peptides. The peptides self-assemble into a gel that essentially seals over the wound. The two developed the technique with MIT colleagues and researchers at the University of Hong Kong.

Sensing calcium as it flows into neurons following firing can potentially track information flow throughout the brain's circuitry. Now, an MIT team has developed a calcium contrast agent for non-invasive magnetic resonance imaging detection. At top, a schematic shows how nanoparticles coated with two proteins (red and green) form mixed aggregates in the presence of calcium. The bottom panel shows ...

MIT researchers have discovered that certain molecules can attach themselves to metallic carbon nanotubes without interfering with the nanotubes' exceptional ability to conduct electricity. At left, the high conductance state has two molecular orbitals, shown in green. Some molecules even let the nanotube switch between highly conductive, left, and poorly conductive (right, with one red molecular ...

This scanning electron microscopy (SEM) image shows MIT's new nanoscale molecular sieve, which consists of thousands of alternating deep (300 nanometers or billionths of a meter) and shallow (55 nanometers) regions. The deep and shallow regions act together to form energy barriers that separate proteins by size. Pores of different sizes can be engineered for different filters to capture specific p...

Sloan Kulper (S.B. 2003) and Audrey Roy (S.B. 2005) have designed a building in the shape of a cell for the Institute for Nanobiomedical Technology and Membrane Biology in Chengdu, China. This illustration shows the exterior in daytime. Protrusions in the facade provide meeting areas attached directly to interior laboratories.
