After that, LS3 was added and the cleaved LS2 on one side of the particles was displaced by LS3 through toehold-mediated strand displacement reaction.
In this way, the cleaved LS-1 DNA in the transparent regions was displaced by LS DNA through toehold-mediated strand displacement reaction (step 5).
So it would slow down the displacement reaction if it were an SN2.
Unlike a DNA strand displacement reaction, the toehold and branch migration domains in a tile displacement reaction consist of a set of edge staples rather than a string of nucleotides (Fig. 1c and Supplementary Fig. 1f).
The effective rate of the overall tile displacement reaction reached a maximum of 4.5 × 105 M−105−105
Another displacement reaction uses gas, with hydrogen sulfide, for example, added to a solution containing nickel sulfate and precipitating nickel sulfide.
In one method, a displacement reaction takes place in which a more active metal replaces a less active metal in solution.
Then the released initiator DNA initiated another autocatalytic strand displacement reaction.
Second, a dimer and a trimer could undergo a displacement reaction to yield a 2 by 2 array while releasing a monomer, and two copies of trimers could also undergo a displacement reaction to yield a 2 by 2 array while releasing a dimer (Supplementary Fig. 1c, dotted arrows).
The idea that inversion is the stereochemical consequence of a nucleophilic displacement reaction was introduced by the British chemists Sir Christopher Ingold and E.D. Hughes (see substitution reaction).
This displacement reaction is not frequently used to synthesize alcohols, however, because alkyl halides are more commonly synthesized from alcohols rather than vice versa.
