چکیده
In this contribution we describe the formation of gold nanoparticles (AuNP)and polyaniline (PANI) AuNP-PANI nanocomposite via in situ enzymaticpolymerization. The method consists electrostatic adsorption aniliniummonomers on AuNPs citrate stabilized surface 50 nm diameters, followedby oxidation with horseradish peroxidase (HRP) enzyme and its cofactorH2O2. All reaction steps were monitored by UV-Vis-NIR spectroscopy includ-ing detection polymerization process. UV-Vis-NIR, Cyclicvoltammetry (CV) enhanced Raman scattering (SERS) measure-ments supported a nanoshell PANI AuNP core. Two templates for anilinium assembly compared revealing strongdependence enzymatic kinetics template. kinetic study hadshown that rigid template contributes to higher rateon more flexible polyanion mildreaction condition enables an easy precise obtaining PANInano-shell anionic advanced bioelectronic applications

Encapsulation of gold nanoparticles by simian virus 40 capsids.
Viral capsid-nanoparticle hybrid structures constitute a new type of nanoarchitecture that can be used for various applications. We previously constructed a hybrid structure comprising quantum dots encapsulated by simian virus 40 (SV40) capsids for imaging viral infection pathways. Here, gold nanoparticles (AuNPs) are encapsulated into SV40 capsids and the effect of particle size and surface li...

BACKGROUND Gold nanoparticles are useful tools for biological applications due to their attractive physical and chemical properties. Their applications can be further expanded when they are functionalized with biological molecules. The biological molecules not only provide the interfaces for interactions between nanoparticles and biological environment, but also contribute their biological func...

Surface chemistry plays a pivotal role in regulating the morphology of nanoparticles, maintaining colloidal stability, and mediating the interaction with target analytes toward practical applications such as surface-enhanced Raman scattering (SERS)-based sensing and imaging. The use of a binary ligand mixture composed of 1,4-benzenedithiol (BDT) and hexadecyltrimethylammonium chloride (CTAC) to...
متن کاملTransport and encapsulation of gold nanoparticles in carbon nanotubes.
Nanoparticles confined in small volumes exhibit functional properties different from that of the bulk material. Furthermore, the smaller the volume available then the greater the effects of confinement are observed to be. Metallic nanoparticles encapsulated within carbon nanotubes have been proposed for many applications ranging from catalysis to quantum storage devices. In this study we examin...
