A composition for use in bioseparation. The composition includes a plurality of hollow particles having a siliceous surface. The composition further includes a surface-modifying agent bonded to the hollow particles. The surface-modifying agent includes a binding segment and a reactive segment. The binding segment includes a silyl group and the reactive segment includes a reactive nitrogen group.

Methods, compositions, devices and kits are provided herein for separating, scavenging, capturing or identifying a metal from a target using a medium or scaffold with a selenium-containing functional group. The medium or the scaffold including the selenium-containing functional group has affinity and specificity to metal ions or compounds having one or more metals, and efficiently separates, recovers, and scavenges of the metals from a target such as a sample, solution, suspension, or mixture.

A process for extracting a surfactant from a mixture using a boronic acid modified material.

This disclosure pertains to mixed mode chromatography ligands and chromatography matrices suitable for the purification of proteins from biological sources or biological samples. Methods of making chromatography matrices comprising the disclosed ligands are also disclosed. Similarly, methods of purifying proteins from a biological sample, source solution, or source liquid using the disclosed chromatography matrices are also provided.

Embodiments of the present disclosure generally relate to organosilane compounds, methods for preparing the organosilane compounds, and products which contain the organosilane compounds. In one or more embodiments, one or more of the organosilane compounds are represented by Formulas (5a), (5b), (5c), (5d), (5e), (5f), (6), (7), (8), (9), (10), (13), (14), (15), (16), (17), and (18). In other embodiments, one or more methods for preparing the organosilane compounds are described and disclosed herein. In some embodiments, one or more products, such as a functionalized inorganic matrix containing the organosilane compound disposed on an inorganic support media (e.g., silica), are described and disclosed herein.
