Controllable Fabrication of Au Nanocups by Confined‐Space Thermal Dewetting for OCT Imaging

Abstract: Here, this study reports a novel confined-space thermal dewetting strategy for the fabrication of Au nanocups with tunable diameter, height, and size of cup opening. The nanocup morphology is defined by the cup-shaped void space created by a yolk-shell silica template that spontaneously takes an eccentric configuration during annealing. Thermal dewetting of Au, which is sandwiched between the yolk and shell, leads to the desired nanocup morphology. With strong scattering in near infrared, the Au nanocups exhib… Show more

“…[19] Despite their interesting properties,methods to synthesize nanocups are only few including DNAo rigami, [20] block copolymer self-assembly, [21][22][23] polymerization-induced buckling, [12] chemical deformation, [24] and templating. [25][26][27][28] These methods have in common that the chemistry of the inside and outside of synthesized cups is typically identical. However,to enhance their selectivity towards interfaces or cargo,itwould be desirable to give cups aJ anus character,that is,adifferent chemistry on the inside and outside.F or the last two decades, Janus particles were synthesized from an umber of materials in various sizes.…”

“…iii) The flourishing development of GNPs with various morphologies provides many possibilities for the core selection of GVs. In addition to the GN, GN string, GNR, GNF, and Janus GN‐Fe 3 O 4 NPs that have successfully assumed the role of GV's cores, GNPs with other shapes could also be the promising cores of GVs . iv) The large cavity of GVs could be loaded with more functional substances.…”

“…[30] Extended from the sol-gel coating approacho fs ilica, Yin's group developed as imilars ol-gel process to coat RF resole on various inorganic nanostructures. [31] Typically, ac ationic surfactant cetyltrimethylammonium bromide (CTAB) plays ad ecisive role in decreasing the repulsive force betweent he negatively chargedi norganic core particles and RF polymers, leading to the formation of au niform RF shell on the surfaceo fc ore particles. Fang et al developed a similar CTAB assisted RF coating strategy to prepare sandwichlike core@silica@RFn anostructures.…”
