Summary | Photo-reactive DNA condensatres are composed of Y-shaped DNA nanostructures (Y-motif), self-assembled from three azobenzene-modified ssDNAs (listed below). The basic sequences are referenced from Y. Sato et al., Sci. Adv. (2020) (DOI: 10.1126/sciadv.aba3471). The azo DNA condensates is capable of reversible phase-state changes upon irradiation of UV or visibile light (Vis). UV leads to an increase in the fluidity (gel-to-liquid or gel-to-dispersed state changes); Vis leads to a decrease in the fluidity (disperse-to-liquid). Thee types of azo sequnces are highlighted: Y_1x7; Y_3x5; Y_2x1x5, in the order of thermostability, wher 'x' refers to the azo insertion site in the SE. When coupled with non-photoresponsive DNA using linker DNA, the resulting condensates show self-collapsing behavior (1x7) and burst-like flow and disassembly–reassembly cycle flow (3x5, 2x1x5) |
