제목 Surface functionalization of conjugated polymer nanoparticles for biosensor applications
초록 Conjugated polymer nanoparticles (CPNPs) have been regarded as an attractive alternate to conventional small molecular optical probes. In bioapplications, CPNPs can be more utilized through chemical/physical modification of their exterior to impart additional functionality as well as inherent photonic properties. However, typical CPNPs have a surface composed of aromatic structure without active functional sites, which may limit further modification on the surface including conjugation of biomolecules. Here, we devised a set of small peptides containing reactive end-functional groups and a molecular structure with high affinity to aromatic molecular. The advantageous features of the CPNPs in the points of tiny colloidal size, stability, bright/stable fluorescence, and capability for further modifications were evaluated to demonstrate a potential for applications to in vitro diagnostic sensor system with high sensitivity for detection of disease-related specific antibodies.
