Scientists develop DNA microcapsules with built-in ion channels

Science Daily  September 18, 2019
By utilising DNA nanotechnology, a team of researchers in Japan designed DNA nanoplates as a nanopore device for ion transportation and stabilised the oil–water interface. Microscopic examination revealed the microcapsule formed by the accumulation of amphiphilic DNA nanoplates at the oil–water interface. Ion current measurements revealed the nanoplate pores functioned as channel to transport ions. These findings provide a general strategy for the programmable design of microcapsules to engineer artificial cells and molecular robots. Such systems could be used to develop artificial neural networks…read more. TECHINCAL ARTICLE
