Mechanically interlocked compounds such as rotaxanes and catenanes are functional molecular media for a host of applications including information storage, mechanical actuation, and drug release.
They describe DNA super-coiling, including its quantitative measure and the geometrical properties of closed- circular DNA, the behavior of DNA on surfaces, knots and catenanes, DNA topoisomerases, and the biological consequences of DAN topology, including genome organization, replication, control of gene expression, transcription, and recombination.
Such molecules, such as catenanes and rotaxanes, were developed in Stoddart's laboratories in the last 20 years, beginning at Sheffield, U.K.
