Adsorbent comprising carboxylic acid dimer and preparation method thereof

An adsorbent includes a porous substrate and a carboxylic acid dimer loaded onto the porous substrate. The carboxylic acid dimer is loaded on the surface or in the plurality of holes of the porous substrate. The average pore size of the porous substrate is not smaller than 2 nm. The carboxylic acid dimer is loaded onto the porous substrate by at least one of the following manners: a) the carboxylic acid dimer is loaded onto the porous substrate through a Si—OH bond; b) the carboxylic acid dimer is loaded onto the porous substrate through the exchange between a carboxyl group and chlorine; c) the carboxylic acid dimer is loaded onto the porous substrate through the exchange between a carboxyl group and a hydroxyl group; and d) the carboxylic acid dimer is loaded onto the porous substrate through the coordination of a carboxyl group and aluminum or silicon.

Bisphenol hypersorbents for enhanced detection of, or protection from, hazardous chemicals

The invention relates to strong hydrogen-bond acidic sorbents. The sorbents may be provided in a form that limits or eliminates intramolecular bonding of the hydrogen-bond acidic site between neighboring sorbent molecules, for example, by providing steric groups adjacent to the hydrogen-bond acidic site. The hydrogen bond site may be a phenolic structure based on a bisphenol architecture. The sorbents of the invention may be used in methods for trapping or detecting hazardous chemicals or explosives.

AFFINITY PURIFICATION OF GLYCOSIDE-CLEAVING ENZYMES

The invention relates to an affinity resin functionalized with small molecule inhibitors of glycoside-cleaving enzymes, e.g., α-galactosidase A (α-Gal A), glucocerebrosidase (GCB), β-galactosidase, and acid alpha-glucosidase (GAA), and a method for purifying glycoside-cleaving enzymes produced in a cell line using the small molecule inhibitor-functionalized affinity resin.
