用于纳米电子学的分子纳米线可以由鸟嘌呤（G）四分体构建块构建。富含鸟嘌呤的 DNA 序列自发组装，形成四分体并进一步排列成四螺旋结构，产生长而连续的单分子 G 线（见图和封面），大概是 G4-DNA，由数千个碱基的单条自折叠聚 (G) 链组成。
Molecular nanowires for nanoelectronics may be built from guanine (G) tetrad building blocks. Spontaneous assembly of guanine-rich DNA sequences that form tetrads and further arrange into a tetrahelix structure produces long, continuous monomolecular G-wires (see Figure and cover), presumably G4-DNA, composed of single self-folded poly(G) strands of thousands of bases.
