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

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.

Fabrication of Bioactive Surfaces by Functionalization of Electroactive and Surface-Active Block Copolymers.

Biofunctional block copolymers are becoming increasingly attractive materials as active components in biosensors and other nanoscale electronic devices. We have described two different classes of block copolymers with biofuctional properties. Biofunctionality for block copolymers is achieved through functionalization with appropriate biospecific ligands.

Procedure for fabricating biofunctional nanofibers.

Electrospinning is an effective processing method for preparing nanofibers decorated with functional groups. Nanofibers decorated with functional groups may be utilized to study material-biomarker interactions i.e.
