Self-Assembling Molecules

Molecules, the smallest structures that comprise matter, assemble themselves into distinct patterns.

Form/Organization/System:: Shape changing

Defense/Stability:: Adhesion

Energy saving

Molecular self-assembly has been used in the development of film with evenly aligned nano-sized pores, as well as in film with honeycomb structures.

Molecular self-assembly can be used to enable the separation of nano-sized materials using self-assembled honeycomb films. For example, nano-filters could separate blood components (white and red blood cells) based on their different sizes, or separate proteins from DNA. Honeycomb film made from self-assembling molecules can be used in regenerative medicine to grow liver cells for use in man-made livers and liver transplants, without harming the body.

: by Robert S. Donovan / CC BY 2.0 Molecular self-assembly is seen in the movement of wine tears (water droplets that accumulate on wine glasses), which is used to determine wine quality. Wine is primarily composed of water and alcohol from fermented grapes. When alcohol evaporates, water molecules are left behind. Water droplets accumulate on the side of the wine glass and flow like tears at even intervals. - From the Amazing Nature Database.
