These developments incorporate unique structures with programmable lattice symmetries and perfectly-defined crystal practices, responsive products that leverage the intrinsic Qualities of nucleic acids to control buildings on demand from customers, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals offering insights into gentle–make any difference interactions. Looking forward, we problem the Local community to leverage the incredible structural Management afforded by crystal engineering with DNA to synthesize courses of purposeful elements that force past what has long been possible with Normally taking place crystalline resources or These produced by more standard strategies.
