Ethylene glycol monolayer protected nanoparticles for eliminating nonspecific binding with biological molecules

Zheng, Ming,Davidson, Fredric,Huang, Xueying

, p. 7790 - 7791 (2003)

The usefulness of the hybrid materials of nanoparticles and biological molecules in many occasions depends on how well one can achieve a rational design based on specific binding and programmable assembly. Nonspecific binding between nanoparticles and biomolecules is one of the major barriers for achieving its utilities in a biological system. In this paper, we demonstrate a new approach to eliminate nonspecific interactions between nanoparticles and proteins by synthesizing ethylene glycol protected gold nanoparticles. We discovered that with the water content optimized in the range of 9-18% in the reaction mixture, di-, tri-, and tetra(ethylene glycol) protected gold nanoparticles Au-S-EGn (n = 2, 3, and 4) could be directly synthesized. These gold nanoparticles that are bonded with a uniform monolayer with defined length varying from 0.8 to 1.6 nm (from molecular modeling) have great stability in aqueous solutions with a high concentration of electrolyte and organic solutions. Using ion-exchange chromatography and gel electrophoresis, we demonstrated that these Au-S-EGn (n = 2, 3, or 4) nanoparticles have complete resistance to protein nonspecific interactions. These types of nanoparticles provide a fundamental starting material for designing hybrid materials composed of metallic nanoparticles and biomolecules. Copyright

Artificial allosteric receptors for nucleotide bases and alkali-metal cations

Inouye, Masahiko,Konishi, Takashi,Isagawa, Kakuzo

, p. 8091 - 8095 (1993)

New allosteric thymine receptors, 2,6-diamidopyridine derivatives tethered to an anthracene ring by a polyoxyethylene chain, were synthesized. In these receptors, binding of 1-butylthymine was enhanced by a factor of 4-6 by recognition of sodium cations, and the changes in the electron density of the anthracene ring were found to have influence on the allosterism by through-space interaction. The anthracene-linked diamidopyridines represent a rationally designed new class of artificial allosteric receptors.

Glycol-functionalized ionic liquids for high-temperature enzymatic ring-opening polymerization

Zhao, Hua,Afriyie, Lennox O.,Larm, Nathaniel E.,Baker, Gary A.

, p. 36025 - 36033 (2018)

Enzymatic ring-opening polymerization (ROP) is a benign method for preparing polyesters, such as polylactides and other polylactones. These reactions are typically carried out at relatively high temperatures (60-130 °C), however, there is a deficiency of enzyme-compatible solvents for such thermally-demanding biocatalytic processes. In this study, we have prepared a series of short-chained glycol-grafted ionic liquids (ILs) based on a phosphonium, imidazolium, pyridinium, ammonium, or piperidinium cationic headgroup. Most of these glycol-grafted ILs exhibit relatively low dynamic viscosities (33-123 mPa s at 30 °C), coupled with excellent short-term thermal stabilities with decomposition temperatures (Tdcp) in the 318-403 °C range. Significantly, the long-term thermal stability under conditions matching those for enzymatic ROP synthesis (130 °C for 7 days) is excellent for several of these task-specific ILs. Using Novozym 435-catalyzed ROP, these ILs are demonstrated to be viable solvents for the enzymatic production of reasonable yields (30-48%) of high molecular mass (Mw ~20 kDa) poly(l-lactide) and poly(?-caprolactone) compared to solventless conditions (12-14 kDa).

Unsurpassed cage effect for the photolysis of dibenzyl ketones in water-soluble dendrimers

Yuan, Zhao,Chen, Jinping,Zeng, Yi,Li, Ying-Ying,Han, Yongbin,Li, Yi

experimental part, p. 6256 - 6264 (2011/10/09)

Amphiphilic water-soluble poly(alkyl aryl ether) dendrimers Gn (n = 1-3) with charge-neutral tetraethylene glycol monomethyl ethers at their periphery were synthesized as microreactors to control the photochemical reactions of dibenzyl ketone derivatives in aqueous solutions. Photophysical studies demonstrated that Gn can encapsulate organic molecules and provide a hydrophobic microenvironment. The product distribution of photolysis of dibenzyl ketone derivatives can be successfully controlled by encapsulating the substrates within dendrimers, and an unsurpassed cage effect of 1.00 is reached in high generation dendrimers, revealing that a thick and compact "shell" was formed at the periphery of the dendrimers. The cage effect is also significantly influenced by the substituent at the para-position of the guest molecules. The higher generation dendrimers exhibit a better confined microenvironment and the aggregates possess more compact cavities to "lock" the guests than the corresponding unimolecular dendrimers. After photolysis, the separation of products can be easily achieved by extracting from the dendrimer solutions and the dendrimers are simply recovered and reused.

Association of Alkali and Alkaline Earth Cations with Benzo-18-crown-6 and Its Neutral and Negatively Charged Acyclic Analogues in Methanol Solution

Ercolani, Gianfranco,Mandolini, Luigi,Masci, Bernardo

, p. 7484 - 7489 (2007/10/02)

The effect of added alkali (Li, Na, K, Rb, and Cs) and alkaline earth (Ca, Sr, and Ba) metal bromides on the acid dissociation of o-hydroxyphenyl 3,6,9,12-tetraoxatridecyl ether (ArOH) in MeOH at 25 deg C has been investigated spectrophotometrically over a wide range of salt concentration.Except for the Li ion, all the investigated salts increased significantly the apparent acidity of ArOH in a way that could be accounted for by the formation of 1:1 addition compounds of the metal cations with both ArOH and its conjugate base ArO-.A proper analysis of the experimental data yielded the equilibrium constants for the formation of the associated species.Complexation of the given cations by benzo-18-crown-6 (C) was also studied spectrophotometrically under the same conditions.The set of equilibrium constants here reported constitute a proper basis for a systematic discussion of the ligation properties of sexadentate ligands with oxygen donors belonging to different structural types.The cyclic ligand C binds cations more strongly than does its open-chain analogue ArOH.The magnitude of the macrocyclic effect is found to be mainly determined by the size of the cation, rather than by its charge.On the other hand, the advantage of the anionic ligand ArO- over ArOH is highly sensitive to the charge of the cation with little or no dependence upon its size.This suggests that direct contact between the oxide ion and the cation is lacking in the ArO-Mz+ species.
