Nanowires that undergo reversible shape changes in response to light could act as artificial tails to steer drugs around the body. Advances in nanotechnology are often inspired by designs found in ...

Scientists in the UK have investigated the phenomenon of shape-selectivity in shape-shifting molecules – molecules that adopt different configurations depending on their environment. Most synthetic ...

An important specialty in this field—and a signature area of study at the University at Albany's RNA Institute—is DNA nanotechnology, wherein the base pairs that comprise DNA molecules are ...

The little spheres represent water molecules. Molecules are in constant motion. The attractions water molecules have for each other keep them close together. They can move past each other, but their ...

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...
