Templated Synthesis of Highly Stable,Electroactive,and Dynamic Metal–DNA Branched Junctions
正文:
DNA has recently emerged as a promising template to create nanostructures with precisely programmed features.[1] Typical approaches involve the assembly of branched units containing unmodified oligonucleotides.[1,2] In contrast,the incorporation of transition metals into the vertices of DNA nanostructures is much less explored.[3] This is despite the tremendous potential of metals to influence both the function of DNA nanostructures,through their redox,photophysical,magnetic,and catalytic properties,as well as the structure of DNA nanoassemblies,through the plethora of geometries and coordination numbers available to them.[3–9] The development of metal–DNA nanostructures is currently hampered by the need to use metals that are kinetically inert,resist the harsh conditions of oligonucleotide solid-phase synthesis,and do not preferentially bind or react with the DNA bases or
phosphate backbone.[3] Furthermore,the limited examples ofmetal–DNA nanostructures have contained metal centers separated byDNAdouble strands,which reduces metal-metal interactions.[3] In order to harness the potential of transition metals as functional corner units in DNA assembly,a more systematic approach that bypasses these limitations is necessary.

模板法合成高穩定性、電活性及動態金屬-DNA分支結
DNA近年來已成爲一種很有前途的創建精確編程功能的納米結構的模板 [1].典型的方法包括含有未修飾的寡核苷酸支化單元的組裝 [1,2].與此相反,過渡金屬摻入到DNA納米結構的頂點卻鮮有探索 [3].儘管金屬在通過其氧化還原性、光物理性質、磁性以及催化性質影響DNA納米結構的功能,以及通過其大量的幾何構型和配位數影響DNA納米組裝結構方面有著巨大的潛力 [3-9].金屬-DNA的納米結構的發展目前受到諸多方面的阻礙,包括需要使用動力學惰性的金屬,不滿足寡核苷酸的固相合成的苛刻條件,不優先與DNA鹼基或磷酸骨架結合或反應[3].此外,有限的金屬-DNA納米結構的例子中包含由DNA雙鏈分離的金屬中心,從而降低了金屬 - 金屬之間的相互作用 [3].爲了利用過渡金屬在DNA組裝中作爲功能角單元的潛力,有必要發展一種更系統的繞過這些限制的方法.
