Johns Hopkins engineers have developed gel strips that change shape when given chemical instructions written in DNA code. These "gel automata," measuring just centimeters, can grow or shrink, ...
(Nanowerk News) Scientists in Japan have made a tuneable, elastic and temperature-sensitive gel by using complementary DNA strands to connect star-shaped polymer molecules together. The gel, and the ...
To visualize DNA or protein in gels, researchers load their samples with colorimetric- or fluorescence-emitting dyes. Typical DNA gel imagers visualize DNA intercalating dyes, such as ethidium bromide ...
