Structure, synthesis, and applications for oligo phenylene ethynylenes (OPEs)

Device and method for detecting the presence of known or unknown toxic agents in a fluid sample. Targets in the sample are bound to releasable receptors immobilized in a reaction region of a micro- or nano-fluidic device. The receptors are selected based on their affinity for classes of known toxic agents. The receptors are freed and the bound and unbound receptors separated based on differential electrokinetic mobilities while they travel to a detection device.

Integrated affinity microcolumns and affinity capillary electrophoresis

Novel compounds generally referred to herein as cationic oligomeric phenylene ethynylenes (OPEs), methods of synthesizing OPEs and various uses for the OPEs are described. The compounds can be synthesized in both symmetrical (S-OPE) and non-symmetrical (N-OPE) forms. Suitable uses include sensor and biocidal applications. Reusable structures incorporating the OPEs that are able to capture and release biological species of interest are also described.

The present disclosure describes the manufacture and use of soft surfaces such as fabrics bearing surface-grafted antimicrobial polymers.

Materials incorporating antimicrobial polymers

A surface grafted conjugated polyelectrolyte (CPE) is formed by coupling a CPE by a coupling moiety to the surface of a substrate. The substrate can be of any shape and size, and for many uses of the surface grafted CPE, it is advantageous that the substrate is a nanoparticle or microparticle. Surface grafted CPEs are presented that use silica particles as the substrate, where a modified silane coupling agent connects the surface to the CPE by a series of covalent bonds. Two methods of preparing the surface grafted CPEs are presented. One method involves the inclusion of the surface being modified by the coupling agent and condensed with monomers that form the CPE in a grafted state to the substrate. A second method involves the formation of a CPE with terminal groups that are complimentary to functionality that has been placed on the surface of the substrate by reaction with a coupling agent. The surface grafted CPEs are also described for use as biosensors and biocides.
