Cancer optical imaging using fluorescent nanoparticles

Cancer optical imaging using fluorescent nanoparticles.

Optical imaging-guided cancer therapy with fluorescent nanoparticles.

The diagnosis and treatment of cancer have been greatly improved with the recent developments in nanotechnology. One of the promising nanoscale tools for cancer diagnosis is fluorescent nanoparticles (NPs), such as organic dye-doped NPs, quantum dots and upconversion NPs that enable highly sensitive optical imaging of cancer at cellular and animal level. Furthermore, the emerging development of...

Bright fluorescent nanoparticles for developing potential optical imaging contrast agents.

Fluorescent cross-linked nanoparticles with variable fluorophore loading amounts, locations, and particle sizes were synthesized from sequential one-pot functionalization/cross-linking of block copolymer micelles with amine-terminated dye and cross-linker molecules, via reductive amination and amidation. The fluorescence quantum yield and brightness of these nanoparticles were evaluated by stea...

Overview of the Optical Properties of Fluorescent Nanoparticles for Optical Imaging

Nanoparticles (NPs) include a wide group of small structures composed by very different materials and characterized by peculiar properties that make them suitable for many applications, especially imaging and drug delivery. In this overview we focus on the optical properties of fluorescent NPs available for in vivo, in vitro and ex vivo preclinical studies and detectable with the optical imagin...

Cancer-targeted optical imaging with fluorescent zinc oxide nanowires.

Herein we demonstrate that intrinsically fluorescent zinc oxide (ZnO) nanowires (NWs) can be adopted for molecularly targeted imaging of cancer cells, after they are functionalized to render water solubility, biocompatibility, and low cellular toxicity. Optical imaging of integrin α(v)β(3) on U87MG human glioblastoma cells was achieved with RGD peptide-conjugated green fluorescent ZnO NWs, whic...
