The present disclosure provides Molecularly Imprinted Polymer (MIP) technology for selectively sequestering one or more target molecules from chemical mixtures. Also disclosed herein are MIP beads and methods of making and using thereof.

Molecularly imprinted polymer beads for extraction of metals and uses thereof

Molecularly imprinted polymer beads for extraction of lithium, mercury, and scandium

A ruggedized hydrogel product that is formulated to withstand the effects of high-energy sterilization procedures, such as gamma beam and electron beam sterilization, without significant structural degradation is disclosed. This enables the hydrogel product to be suitable for use in medical applications where sterile components are required. In one embodiment a ruggedized hydrogel product is disclosed and comprises a gel component, water for hydrating the gel component, and at least one free radical absorber component that is capable of absorbing free radicals produced when the hydrogel product is sterilized via a high-energy sterilization procedure. The free radical absorber component in one embodiment includes potassium metabisulfite and ascorbic acid. The ruggedized hydrogel product can be included with an ultrasound probe to provide an acoustically transparent interface between the probe and the skin of a patient.

Ruggedized ultrasound hydrogel insert

A molecularly imprinted polymer ion exchange resin for selectively removing one or more inorganic ions in a liquid medium is disclosed and described. The exchange resin can include a bead having a porous structure and comprising a cross-linked molecularly imprinted polymer having molecular sized cavities adapted to selectively receive and bind a specific inorganic ion in a liquid medium. A process for preparing a molecularly imprinted polymer ion exchange resin can include (a) polymerizing a polmerizable mixture in the presence of an inorganic ion imprinting complex to form a bead, said inorganic ion imprinting complex including a ligand and an inorganic ion; and (b) removing the inorganic ions from the bead to form the molecularly imprinted polymer ion exchange resin, the bead having a porous structure and comprising a cross-linked molecularly imprinted polymer having molecular sized cavities adapted to selectively receive and bind a specific inorganic ion in an liquid medium.

Process for preparing molecularly imprinted polymer ion exchange resins

A process is provided herein for preparing molecularly imprinted polymers for detecting a target analyte by Reversible Addition Fragmentation Chain Transfer (RAFT). The process includes providing a complex having the formula LM wherein L is a &#x3b2;-diketone ligand containing a chain transfer moiety and Lcan be the same or different ligands, and M is a lanthanide element; reacting the complex with the target analyte to provide an adduct containing the target analyte; co-polymerizing the adduct with a monomer and cross-linking agent to provide a polymer; and removing the target analyte from the polymer to provide the molecularly imprinted polymer.

Processable molecularly imprinted polymers

A method of creating a cationic molecularly imprinted polymer bead that can bind inorganic target compounds is disclosed and described. The cationic molecularly imprinted polymer bead can be formed by complexing a target compound with a cationic ligand, polymerizing the cationic ligands to form the bead, and then extracting the target compound from the bead. The cationic ligand complex can have an octanol water partition coefficient of about 1 to about 10. The cationic molecularly imprinted polymer bead can have a porous structure containing a plurality of complexing cavities for selectively bind specific target compounds for removal from potable water, mine effluent, industrial effluent, or other fluids.

Molecularly imprinted polymers (MIPS) for the selective removal of inorganic contaminants from liquids

A food spoilage sensor of the general formula wherein M is a transition metal ion; D, D, Dand Dcan be the same or different and can be N or P; Rand R, Rand R, Rand R, and Rand Rcan be the same or different and from, taken together with the adjacent carbon atoms to which they are bonded and joined together, an aromatic or a cyclic group with at least one of the aromatic or cyclic groups possessing one or more polymerizable moieties. The complex selectively binds biogenic amines which are released by food spoilage microorganisms and undergo a detectable color change upon exposure thereto.

Sensor for monitoring an analyte

A system for detecting neutron radiation. A liquid cocktail mixture comprised of a neutron absorber and a scintillator is housed in a Teflon&#xae; tube having a mirror at one end of the tube and a windowed portal at the other end of the tube. Neutrons that penetrate the tube react with the neutron absorber producing ionization that excites a scintillator to produce photons. A photo-multiplier tube is coupled with the windowed portal for receiving photons and converting the photons to electrical signals. A processing device is coupled to the photo-multiplier output for receiving and analyzing the electrical signals so as to provide a measurement pertaining to the presence and relative strength of neutron radiation. The tube can be adapted to function as a portable survey instrument. Alternatively, the tube can be stretched to cover large apertured areas. In such implementations a wavelength shifter is employed to convert light emitted to another wavelength giving a multiplier effect necessary for long light guides.

Neutron detection based on boron activated liquid scintillation

A process for preparing vinyl substituted beta-diketones includes reacting a halogen-containing beta-diketone with an olefin in a reaction zone under Heck coupling reaction conditions in the presence of a catalyst, a base, and an organic phosphine to provide a vinyl substituted beta-diketone product.
