Cycloparaphenylenes (CPPs) have optoelectronic properties that are unique when compared to their acyclic oligoparaphenylene counterparts. The synthesis and characterization of two bent heptaphenyl-containing macrocycles has been achieved in order to probe the effects of bending and cyclic conjugation on the properties of the CPPs. The study suggests that… (More)
We report on the aqueous preparation of novel polymeric bionanocomposites (PBNCs) with polydopamine (PDA) as an efficient matrix to support antibody and uniformly dispersed abundant Pt nanoparticles (PtNPs) for high performance sandwich-type amperometric immunoassay. We prepare three kinds of PBNCs (PBNCs 1, 2, and 3) via chemical polymerization synthesis… (More)
A simple and efficient post-labeling strategy based on dye-induced peeling of the aptamer molecules off single-walled carbon nanotubes was developed for electrochemical aptasensing of thrombin with a detection limit down to 3 pM.
Nanoscale carbon-rich molecular architectures are not only aesthetically appealing but also of practical importance for energy and biomedical technologies. Herein, we report the synthesis of cyclic-oligophenylene-based nanopropeller 1 by using an efficient synthon strategy involving sequential intramolecular bisboronate homocoupling and reductive… (More)
Cycloparaphenylenes (CPPs) and their derivatives are unique conjugated macrocycles with novel optoelectronic and host-guest properties. A better understanding of their reactivity is essential for creating new functional materials utilizing these strained aromatic molecules as building blocks. 1,4-Anthracene-incorporated CPP 1 was synthesized and exhibited… (More)
We report on the exploitation of metal-organic coordination polymers (MOCPs) as new and efficient matrixes to immobilize enzymes for amperometric biosensing of glucose or phenols. A ligand, 2,5-dimercapto-1,3,4-thiadiazole (DMcT), two metallic salts, NaAuCl(4) and Na(2)PtCl(6), and two enzymes, glucose oxidase (GOx) and tyrosinase, are used to demonstrate… (More)
