Intercalation is the reversible inclusion or insertion of a molecule (or ion) into layered materials with layered structures. Examples are found in graphite and transition metal dichalcogenides . [ 1 ] [ 2 ]
Intercalation may refer to: Intercalation (chemistry) , insertion of a molecule (or ion) into layered solids such as graphite Intercalation (timekeeping) , insertion of a leap day, week or month into some calendar years to make the calendar follow the seasons
Intercalation induces structural distortions. Left: unchanged DNA strand. Right: DNA strand intercalated at three locations (black areas). In biochemistry, intercalation is the insertion of molecules between the planar bases of deoxyribonucleic acid (DNA). This process is used as a method for analyzing DNA and it is also the basis of certain ...
The intercalation compounds graphite bisulfate and graphite perchlorate can be prepared by treating graphite with strong oxidizing agents in the presence of strong acids. In contrast to the potassium and calcium graphites, the carbon layers are oxidized in this process:
[11] [12] After intercalation, the sample can be photoactivated by absorbing energy during irradiation with short wavelength light. [1] This activation causes the metallo-intercalator's photooxidative properties to induce a cleavage of the sugar phosphate backbone at the site of mismatch through a radical mechanism.
Intercalation or embolism in timekeeping is the insertion of a leap day, week, or month into some calendar years to make the calendar follow the seasons or moon ...
Intercalation-induced supercoiling of DNA [ edit ] Based on the properties of intercalating molecules, i.e. fluorescing upon binding to DNA and unwinding of DNA base-pairs, in 2016, a single-molecule technique has been introduced to directly visualize individual plectonemes along supercoiled DNA [ 5 ] which would further allow to study the ...
Ethidium bromide (or homidium bromide, [2] chloride salt homidium chloride) [3] [4] is an intercalating agent commonly used as a fluorescent tag (nucleic acid stain) in molecular biology laboratories for techniques such as agarose gel electrophoresis.
