A pH responsive DNA walker has been designed by scientists in China.
Jingsong Ren and colleagues from the Chinese Academy of Sciences, have shown that the walker can reversibly transport specific molecules along an assembled track under environmental stimuli.
The team believe that this work is an important step in obtaining artificial nanomotors with precise motion control and will be highly beneficial for future applications and complex operations in diverse areas ranging from drug delivery to nanoscale assembly or patterning.
