ABSTRACT
Four different conjugated polymer nanoparticles (CPNs) were used to differentiate structurally similar glycosaminoglycans (GAGs) in a urine simulant. Unique emission response patterns of CPNs were analyzed by linear discriminant analysis (LDA), confirming that structurally diverse CPNs are sensitive and effective at differentiating GAGs in a complex biological medium.

We developed a new synthetic approach to high molecular weight poly(p-phenylenebutadiynylene) s (PPBs) by increasing backbone flexibility. The introduction of a small amount of flexible units along the backbone improved both the physical and photophysical properties of the polymers. These materials were successfully fabricated into conjugated polymer nanoparticles (CPNs) and used for fluorescent live cell imaging for the first time.
