Sensing clinically relevant biomolecules is crucial for the detection and prevention of disease. Currently used detection methods tend to be expensive, time intensive, and specific for only one particular biomolecule of interest. Nanoparticle-based arrays using conjugated polymers have emerged as an analytical and potential clinical tool, allowing detection of a wide range of biomolecules using selective, not specific, sens Read More

By means of the modular construction of a large series of poly(arylene ethynylene)s (PAEs) employing Pd-promoted synthetic routes, molecular models of type A—C≡C—B-C≡C—A and B—C≡C—A—C≡C—B, and polymers of type [—C≡C—A—]n and [—C≡C—A—C≡C—B—]n carrying a variety of aminoacidic side arms, have been prepared and fully characterized towards their application as sensing materials. The introduction o Read More
