摘要： The present invention provides novel compositions of binding moiety-nanoparticle conjugates, aggregates of these conjugates, and novel methods of using these conjugates, and aggregates. The nanoparticles in these conjugates can be magnetic metal oxides, either monodisperse or polydisperse. Binding moieties can be, e.g., oligonucleotides, polypeptides, or polysaccharides. Oligonucleotide sequences are linked to either non-polymer surface functionalized metal oxides or with functionalized polymers associated with the metal oxides. The novel compositions can be used in assays for detecting target molecules, such as nucleic acids and proteins, in vitro or as magnetic resonance (MR) contrast agents to detect target molecules in living organisms.

摘要： An intramolecularly-quenched, near infrared fluorescence probe that emits substantial fluorescence only after interaction with a target tissue (i.e., activation) is disclosed. The probe includes a polymeric backbone and a plurality of near infrared fluorochromes covalently linked to the backbone at fluorescence-quenching interaction-permissive positions separable by enzymatic cleavage at fluorescence activation sites. The probe optionally includes protective chains or fluorochrome spacers, or both. Also disclosed are methods of using the intramolecularly-quenched, near infrared fluorescence probes for in vivo optical imaging.
