Bioengineering and biotechnology

The top image shows a mixture of gold nanoparticles. The longer particles are called nanobones, and the smaller are nanocapsules. Bottom left: After the nanoparticles are hit with 800 nanometer wavelength infrared light, the nanocapsules melt and release their payload. Nanobones remain intact. Right: After the nanoparticles are hit with 1100 nanometer wavelength infrared light, the nanobones melt...

Kinesin, a small motor protein found in cells, walks stepwise onÂ microtubules to perform cellular processes. In each step, a powerÂ stroke is generated when two mechanical elements (neck linker, in red, and cover strand, in blue) form a beta-sheet that folds to drive the protein forward.
