Throughout history, mankind has attempted to mimic the natural world—building wings to fly
like the birds and fabricating systems to harness energy from the sun like our botanical …

Bistable catenanes have the potential to serve as molecular-scale switches and machines.
We have chosen to study an electrochemically-switchable [2]catenane consisting of a …

(57) ABSTRACT The present invention includes a chemical monolayer construction that
comprises:(a) a substrate having a contact surface; and (b) a plurality of substantially parallel …

Conventional microprocessors use elementary logic gates to perform complex computational
tasks. Mimicking such computational processes using purely molecular systems has been …

Nanoscale mobile devices (nanomotors) have many potential applications, such as information
processing, nanoelectronic devices, biosensors, and regulation of chemical reactions …

Two switchable neutral bistable [2]rotaxanes have been synthesized, and their chemically
induced mechanical switching has been studied in solution by 1 H NMR spectroscopy. One of …

Many phenomena of biological interest originate directly from mechanical motions at the
molecular level. Celebrated examples include the trans-cis isomerisation of double bonds that …

A functioning nanomachine in the form of a supramolecular nanovalve that opens and
closes the orifices to molecular-sized pores and releases a small number of molecules on …

Olefin metathesis has been employed in the efficient syntheses of a [2]catenane with the
templation being provided by the recognition between a secondary ammonium ion and a crown …

Human sensory receptors transduce chemical, light, mechanical, and thermal stimulations
into nerve impulses, which are transmitted to the brain. 1 This sequence of events involves a …
