Mechanically interlocked sub-atomic architectures are atoms that are associated as an outcome of their topology. This association of particles is comparable to keys on a key chain circle. The keys are not straightforwardly associated with the key chain circle yet they can't be divided without breaking the circle. On the sub-atomic level the interlocked atoms can't be divided without critical contortion of the covalent bonds that make up the conjoined particles. Samples of mechanically interlocked atomic architectures incorporate catenanes, rotaxanes, sub-atomic bunches, and sub-atomic Borromean rings.
The union of such entrapped architectures has been made effective through the combo of supramolecular science with customary covalent combination, however mechanically interlocked sub-atomic architectures have properties that vary from both supramolecular congregations and covalently reinforced particles. As of late the wording mechanical bond has been begat to depict the association between the parts of mechanically interlocked atomic architectures. Despite the fact that exploration into mechanically interlocked sub-atomic architectures is principally centered around counterfeit mixes, numerous illustrations have been found in natural frameworks including: cystine hitches, cyclotides or tether peptides, for example, microcin J25 which are protein, and a mixture of peptides. There is a lot of enthusiasm toward mechanically interlocked sub-atomic architectures to create sub-atomic machines by controlling the relative position of the parts.
