Introduction to Fluorescent Core

Such silver film masks the fluorescent core of the bead inversely proportional to the concentration of antigen in a sample.

Ultrasmall (diameter below 10 nm) fluorescent core–shell silica nanoparticles have garnered increasing attention in recent years as a result of their high brightness and favorable biodistribution properties important for applications including bioimaging and nanomedicine.

Applying a combination of high-performance liquid chromatography (HPLC) and gel permeation chromatography (GPC) to ultra-small (<10 nm diameter) poly(ethylene glycol)-coated (PEGylated) fluorescent core-shell silica nanoparticles, we elucidate here previously unknown surface heterogeneities resulting from varying dye conjugation to nanoparticle silica cores and surfaces.

Poly(aryl-ether) dendrimers grown from fluorescent cores, such as 1,3,5-triarylbenzene or meso-porphyrins, have been decorated with boron clusters to attain rich boron containing dendrimers.

In addition, the high-bandgap carbazole terminal substituents are introduced to protect the hyper-fluorescent core by a cascade energy transfer channel.

Here, a new set of magneto-fluorescent core-shell nanostructures were formed from the Ni-Zn-ferrite as magnetic core and CdS quantum dots as fluorescent semiconducting shell with exceptional physical and chemical properties of individual magnetic core and QDs shell.

The hydrophobicity of the fluorescent core was systematically modified by conjugation with 10 different commercial amines.

Fluorescent core-shell particles are used as versatile fluorophores in confocal microscopy based image analysis and as a colloidal model system to study short and long-range interactions.
