“…Carbon dots (CDs) is a rising star in luminescent materials due to their low cost, [11] nontoxic [12, 13] and easily synthetic approach, [14] which can show room temperature phosphorescence (RTP) by incorporating into a solid host matrices, [15–17] including organic materials (such as, poly (vinyl alcohol) [18–20] and polyurethane [21] ) and inorganic materials (such as KAl(SO 4 ) 2 ⋅x(H 2 O), [22] layered double hydroxides, [23] amorphous silica [24, 25] and zeolites [26–27] ). This provides a clue that the luminescent behavior of CDs can be regulated according to the selection of the host matrices.…”

Time‐dependent Phosphorescence Color of Carbon Dots in Binary Salt Matrices through Activations by Structural Confinement and Defects for Dynamic Information Encryption

The emergence of time-dependent phosphorescence color (TDPC) materials has taken information encryption to high-security levels. However, due to the only path of exciton transfer, it is almost impossible to obtain TDPC for chromophores with a single emission center. Theoretically, in inorganic-organic composites, the exciton transfer of organic chromophores depends on the inorganic structure. Here, we assign two structural effects to inorganic NaCl by metal (Mg 2 + or Ca 2 + or Ba 2 + ) doping, which triggers the TDPC performance of carbon dots (CDs) with a single emission center. The resulting material is used for multi-level dynamic phosphorescence color 3D coding to achieve information encryption. The structural confinement activates the green phosphorescence of CDs; while the structural defect activates tunneling-related yellow phosphorescence. Such simply doped inorganic matrices can be synthesized using the periodic table of metal cations, endowing chromophores with tremendous control over TDPC properties. This demonstration extends the design view of dynamic luminescent materials.

“…DNA processing enzymes have been applied to synthetic DNA constructs since the outset of DNA nanotechnology. , Because the DNA duplex segments constitute the major body of a DNA nanostructure, it is natural to use enzymes from the molecular cloning toolbox for the specific modifications of synthetic DNA constructs. − For example, polymerases can be used to fill gaps of double-stranded DNA, − restriction enzymes can be applied to cleave specific sequence motifs to create nicks for short strands in DNA nanostructures, − and ligase can also be used to seal nicks for multiple short strands to be combined covalently. ,,,− Upon enzymatic processing, new features are brought to the resulting constructs. More importantly, DNA nanostructure dynamics of a higher level of controllability and reliability induced by enzymatic treatments could lead to the precise execution of advanced computation.…”

Golden Gate assembly is a popular molecular cloning method to assemble multiple DNA fragments in a “one-pot” enzymatic reaction. Taking advantage of the high combination efficiency provided by the enzyme cocktail of this assembly method, we present a controllable assembly system of synthetic DNA nanostructures in this work. Similar to the rendering of duplex fragments to be assembled in Golden Gate assembly, type II restriction enzyme creates specific sticky end pairs for the DNA nanostructure units to connect, and ligase consolidates the sticky end cohesion, which collectively enables the corresponding hierarchical assembly. By application of this molecular cloning method in DNA self-assembly, the enzymatic treatment leads to the production of a number of high-order DNA nanostructures.
