SELF-ASSEMBLING SYNTHETIC TENTACLES

A major goal of synthetic biology is to engineer unnatural molecules and compounds into systems and tools that mimic those found in biology.
Pictured here are self-assembling synthetic nanofibers in capture-and-release devices that look strikingly like tiny fingers (or tentacles).

- The bristles are made of epoxy resin and then immersed into a liquid.
- As they dry, they grab whatever is nearby, such as a drug or small nanoparticles.
- The bristles store energy and thus, can be made to release the item.
- Each bristle here is ~1/1000th the width of a human hair.
