The article discusses the creation of hybrid rotaxane structures by a team led by chemists David A. Leigh and Richard E. P. Winpenny from linear secondary amine threads and hetero-metallic rings in Great Britain. It states that one of the hybrid rotaxanes acts as a molecule shuttle. Leigh said that the hybrid molecule is the first example of a discrete molecule linking organic and inorganic components at the molecular level.

The article reports that a team of researcher led by Emilio M. Pérez of Madrid Institute for Advanced Studies in Nanoscience in Spain have developed a strategy for tying a macrocylce around a single-walled carbon nanotube (SWNT) to create a rotaxane, as of April 2014.

The article reports that a team of researchers at the University of Edinburgh in Scotland has developed rotaxanes derived from synthetic peptide macrocycles and nonpeptidic diammonium threads. Rotaxanes is a bead-on-a string type structure in which a linear molecule threads through at least one cyclic molecule. According to researchers, synthetic peptide rotaxanes may provided insights into natural interlocked systems.

Highlights the meeting "From Clever Molecules to Smart Materials" in Tomar, Portugal. Discussion on artificial molecular machines and supramolecular chemistry; Development of interlocked rotaxane and catenane molecules into switches for electronic devices; Change in the material's color by the application of a voltage that switches the machine between its ground state and its metastable state.

The article reports that J. Fraser Stoddart, a chemistry professor at the University of California in Los Angeles, will be knighted by Queen Elizabeth II in the later part of 2007. Stoddart's knighthood recognizes his pioneering work on the use of molecular recognition and self-assembly to synthesize interlocked compounds known as catenanes and rotaxanes.

The article reports that researchers at California Institute of Technology (Caltech) in Pasadena have developed a memory circuit the size of a white blood cell, which they claim as the densest memory circuit ever fabricated. According to the researchers, the 160,000 memory bits are arranged like a tic-tac-toe board. Its molecular switches, called rotaxanes, consist of two interlocking components, that are similar to a wedding band on a finger.
