Valency Control and Functional Synergy in DNA‐Bonded Nanomolecules

Abstract: The rapid development of DNA nanotechnology has enabled ap recise organization of nanoscale matter with ultimate structural programmability.I np articular,D NAbonded discrete nanoparticle assemblies ("nanomolecules") have the potential to allow sophisticated functional realizations of inorganic nanomaterials via molecule-like structural controls. Such an ambitious goal may gradually become achievable, encouraged by recent advancements in related fields. Twok ey issues must first be solved in order to realize s… Show more

“…[35][36][37] However, a strong capacitive coupling or direct charge transfer is oen prohibited in these assemblies by the bulky DNA strands. 38,39 To circumvent this problem, dried samples (unexpected due to structural disruption) are oen used, as capillary forces generated during water evaporation can bring NPs in close contact. [40][41][42] Apart from self-assembly, direct synthesis of interfaced plasmonic nanodimers is possible but producing gapped structures is hard.…”

“…Larger, superparamagnetic and superferromagnetic nanoparticles (NPs) behave in many ways like atoms of paramagnetic and ferromagnetic metals, respectively 4 , 5 . Various ways of encoding “valency” in spherical NPs have been proposed 6 and utilized for constructing “colloidal molecules” 7 . NPs can also be assembled into onedimensional structures in a process similar to the polymerization of small molecules 8 ; indeed, the ability to visualize NPs by electron microscopy has been utilized to validate theoretical models developed for molecular polymerization.…”

“…上述"干态"结构也不适合化学和生物溶液 体系的应用. 自组装是制备纳米二聚结构的常用方 法 [2,[25][26][27][28][29] , 但组装结构难以发生粒子间电荷转移 [30][31][32] . 最近, Deng 等 [33][34][35] 结合自组装与限域热(或激光)烧结, 制备出不同导电结宽度的二聚结构.…”
