Microspiders: Polymerization reaction drives micromotors

(PhysOrg.com) -- Though it seems like science fiction, microscopic "factories" in which nanomachines produce tiny structures for miniaturized components or nanorobots that destroy tumor cells within the body and scrape blockages ...

Giant molecule synthesized

Producing molecules comparable with large bio-molecules in size, shape and structure is an age-old dream of organic chemists. An international research team led by A. Dieter Schluter from the Department of Materials Science ...

Scientists identify spontaneously chain-reacting molecule

In the burgeoning field of nano-science there are now many ways of 'writing' molecular-scale messages on a surface, one molecule at a time. The trouble is that writing a molecule at a time takes a very long time.

Molecules delivering drugs as they walk

An octopus-like polymer can "walk" along the wall of a narrow channel as it is pushed through by a solvent. Now research in The Journal of Chemical Physics, which is published by the American Institute of Physics, provides ...

Chemists discover twisted molecules that pick their targets

New York University chemists have discovered how to make molecules with a twist—the molecules fold in to twisted helical shapes that can accelerate selected chemical reactions. The research, reported in the latest issue ...

Why retroviruses such as HIV love their neighbors

Retroviruses such as HIV that are already within cells are much more easily transmitted when they are next to uninfected cells than if they are floating free in the bloodstream.

Monitoring Cancer Cell Changes With Quantum Dots

One of the earliest events that changes a normal cell into a malignant one is known as deoxyribonucleic acid (DNA) hypermethylation, a biochemical alteration that inactivates critical tumor-suppressor genes. A team of investigators ...
