This paper reports the colorimetric and resonance scattering (RS)-based biosensor for the ultrasensitive detection of As(III) in aqueous solution via aggregating gold nanoparticles (AuNPs) by the special interactions between arsenic-binding aptamer, target and cationic surfactant. Aptamers and the cationic surfactant could assemble to form a supramolecule, which prevented AuNPs from aggregating...

Supramolecule self assembly polyamidoamine (PAMAM) dendrimer refers to the chemical systems made up of a discrete number of assembled molecular subunits or components. These strategies involve the covalent assembly of hierarchical components reactive monomers, branch cells or dendrons around atomic or molecular cores according to divergent/convergent dendritic branching principles, systematic f...

In summary, a novel structure of MOF based on 1,4–di ([2,2':6',2''terpyridin] -4'-yl)benzene and 1,4-naphthalenedicarboxylic acid has been constructed through hydrothermal reaction. The Ni-MOF displays one dimensional zigzag chain, which connect each other by hydrogen bonding to form three supramolecule with large channels. conjugated systems the terpyridin benzene ligands enhance chain rigidit...

The synthesis and properties of large spherical molecules and giant clusters is a fascinating field in contemporary chemistry, unifying all areas of organic/supramolecular, inorganic, and coordination chemistry as well as organometallic chemistry. Recent developments of low-valent group 13 metalloid clusters,1 chalcogeno-bridged copper, and silver clusters2 as well as giant polyoxomolybdates3 r...

Nanopatterning and functionalizing of graphene is often required to tune or enhance its unique physical properties. However, complex processes are needed to overcome the chemical incompatibilities between the patterning template, the functional small molecules or nanoparticles, and the underlying graphene. We present a block copolymer (BCP)-based supramolecular thin film as a versatile platform...

Rotaxanes are known for the mechanically interlocked molecules decades. The present work demonstrates a method to prepare multi-responsive rotaxane by conjugating with supramolecule. Benzoxazine dimers, N, N’-bis(3,5-dimethyl-2-hydroxybenzyl) methylamine derivatives, good models because their simple chemistry. An azobenzene containing benzoxazine remaining hydroxyl group further conjugation was...

Meso-scale simulation of structure formation for AB-dimers in solution W monomers was performed by dissipative particle dynamics (DPD) algorithm. As a simulation model, modified Jury Model was adopted [Jury, S. et al. “Simulation of amphiphilic mesophases using dissipative particle dynamics,” Phys. Chem. Chem. Phys. 1 (1999) 2051–2056], which represents mechanics of self-assembly for surfactant...
