Nano-Snowflower of Gold Nanoparticles-Ruthenium Metallopolymer-Carbon Nanotubes Binding Anti-DNP IgE Antibody

摘要

Gold nanoparticles (AuNPs) have been chemically functionalized onto multiwalled carbon nanotubes (MWCNT) through a metallopolymer linker-bis (2,2':6'2 ''-terpyridine) ruthenium(II)-connected diblock poly(N-isopropyacryamide). A "nano-snowflower" pattern was formed by self-assembly MWCNT-AuNP nanocomposite with anti-DNP IgE antibody. MWCNT-AuNP nanohybrid has unique biocompatibility and electronic current voltage properties. This nanohybrid shows the potential application for IgE biosensor to diagnose cancer cells. We represent a step towards building complex electronic circuits response by providing molecular recognition properties.
