The present invention relates to a method of preparing a molecular sensor that is specific for a target molecule having a saccharide or peptide region. The method comprises using the target molecule as a template and incubating the template with a receptor to form a template-receptor complex. A molecular scaffold is formed on a surface around the template-receptor complex such that the receptor and at least a portion of the template are embedded in the scaffold, and the template is removed to produce a cavity defined by the scaffold, such that the cavity is complementary to at least a portion of the saccharide or peptide region of the target molecule.

Crosslinked molecularly imprinted polymers (MIPS) and methods for the same are provided. The crosslinked MIP may include a crosslinked polymer molecularly imprinted to have specific affinity for binding with a target substance. The target substance may include one or more perfluoroalkyl or polyfluoroalkyl substances (PFAS). The crosslinked polymer may be molecularly imprinted with the target substance, an analog of the target substance, or a combination thereof. Methods for utilizing the crosslinked MIP may include contacting the crosslinked MIP with an aqueous composition including the target substance, and adsorbing at least a portion of the target substance of the aqueous composition with the crosslinked molecularly imprinted polymer.

The invention relates to a molecularly imprinted polymer, wherein the molecularly imprinted polymer comprises a functionalized polymer composition configured to molecularly bind a target molecule in a medium, wherein a chelating agent is molecularly bound to the functionalized polymer composition of the molecularly imprinted polymer, said chelating agent is releasable to the medium and is able to induce a change in the electrochemical properties of the medium once released from the molecularly imprinted polymer, and wherein the chelating agent is configured to be released to the medium from the molecularly imprinted polymer by molecular binding of the target molecule to the functionalized polymer composition of the molecularly imprinted polymer.

Disclosed herein is a method of making a polymeric material for selective adsorption of a gas. The method comprises dissolving a monomer comprising a functional group having an affinity for the gas in a solvent with a cross-linker and an initiator; emulsifying the solution in a liquid which is inimiscible with the first solvent; and agitating and heating the enmulsion to cause polymerization of the monomer into a cross-linked polymer having nanocavities with functional groups covalently-incorporated on walls thereof. Also disclosed are polymeric particles, an apparatus for forming the particles and a method of adsorbing a selected gas

A liquid contaminant absorbent and a method for fabricating a liquid contaminant absorbent. The method includes the steps of: mixing polydopamine nanospheres (SPDA) with a template agent in a predetermined mixing ratio to form a precursor mixture; dissolving the precursor mixture in a solvent to initiate a reaction within the precursor mixture; obtaining a precipitate from the precursor mixture after a predetermined reaction period; and removing the template agent from the precipitate to obtain mesoporous polydopamine nanoparticles (MPDA).
