In gel electrophoresis, the molecules to be separated are pushed by an electrical field through a gel that contains small pores. The molecules travel through the pores in the gel at a speed that ...

Exclusion chromatography can be used to separate molecules on the basis of size 1,2. The technique described here, which uses gel filtration to separate high-molecular-weight DNA from smaller ...

The sol-gel synthesis process begins with the preparation of a sol, where metal or metalloid precursors are dissolved in a solvent. These precursors undergo hydrolysis and polymerization reactions, ...

These "gel automata," measuring just centimeters, can grow or shrink, transforming from one letter or number to another when triggered by specific DNA molecules. This breakthrough opens ...

The gel will slowly rise in the cup. That’s what happened in the diaper to make all ... To answer these kinds of questions using chemistry, we have to think about the atoms and molecules that the ...

Professor Jonathan Steed Professor Steed is fascinated by the way in which chemical molecules assemble – like Lego blocks – to give complex, functional structures. Gel (and jelly), for example, ...
