Multifunctionalized flower-like gold nanoparticles with high chemiluminescence for label-free sensing of the hepatitis C virus core protein

Abstract

Developing functionalized nanomaterials with strong chemiluminescence (CL) properties is highly significant for ultrasensitive bioanalysis. Here, we reported chitosan (CS), luminol, and Co2+-functionalized flower-like gold nanoparticles (Co2+/CS/Lum/AuNFs) with a strong CL...

For example, chemiluminescence was enhanced by aggregating Au NPs with complex DNA networks (CDNs).…”

Boosting Photon Emission from the Chemiluminescence of Luminol Based on Host–Guest Recognition for the Determination of Dopamine

“…Among them, a nanomaterial-based amplified strategy has been widely adopted to boost the total emission photon for high performance. − Considering the CL boosting reaction mechanism, the amplified strategies based on the functional nanomaterials can be categorized into two types. The first type is based on the high reactivity of nanomaterials as a catalyst to accelerate the decomposition of coreactants and increase the generation efficiency of free radicals, which in turn enhances the luminescence intensity. − For example, Cui’s group has carried out the systematic research since 2005 and demonstrated the role as catalysts of nanomaterials in CL systems. , They found that gold nanoparticles (AuNPs) with different sizes can be acted as catalysts to accelerate the decomposition of H 2 O 2 into hydroxyl radicals ( • OH) and the resulting • OH may be stabilized by AuNPs through partial electron-exchange interactions, thus enhancing the CL emission . Furthermore, nanocomposites have been widely used in CL analysis due to their excellent catalytic properties. − Amirzehni’s group produced the copper metal–organic framework decorated with cobalt oxide nanoparticles (Co 3 O 4 @CuMOF), in which the synergistic interaction of copper and cobalt greatly enhances the catalytic performance based on the peroxidase-like activity and significantly enhanced the CL emission of the rhodamine B–H 2 O 2 CL system .…”
