چکیده

A polymer and silica co-protection strategy has been developed to encapsulate organic fluorogens with aggregation-induced emission and charge transfer characteristics into small nanoparticles (NPs). The co-pretected NPs show bright red fluorescence (50% quantum yield) with a large two-photon action cross-section (450 GM at 840 nm), which have been sucessfully used for two-photon fluorescence imaging of vasculature of the mouse tibial muscle.

Chemical nature and structure of organic coating of quantum dots is crucial for their application in imaging diagnostics

BACKGROUND One of the most attractive properties of quantum dots is their potential to extend the opportunities for fluorescent and multimodal imaging in vivo. The aim of the present study was to clarify whether the composition and structure of organic coating of nanoparticles are crucial for their application in vivo. METHODS We compared quantum dots coated with non-crosslinked amino-functio...

Lipid-PEG-folate encapsulated nanoparticles with aggregation induced emission characteristics: cellular uptake mechanism and two-photon fluorescence imaging.

Folate functionalized nanoparticles (NPs) that contain fluorogens with aggregation-induced emission (AIE) characteristics are fabricated to show bright far-red/near-infrared fluorescence, a large two-photon absorption cross section and low cytotoxicity, which are internalized into MCF-7 cancer cells mainly through caveolae-mediated endocytosis. One-photon excited in vivo fluorescence imaging il...

Two-photon excited fluorescence of silica nanoparticles loaded with a fluorene-based monomer and its cross-conjugated polymer: their application to cell imaging.

In this work the two-photon activity of nanoparticles obtained from a fluorene monomer (M1) and its cross-conjugated polymer (P1) is reported. Aqueous suspensions of M1 and P1 nanoparticles prepared through the reprecipitation method exhibited maximum two-photon absorption (TPA) cross-sections of 84 and 9860 GM (1 GM = 10(-50) cm(4) s) at 740 nm, respectively, and a fluorescence quantum yield o...

CdSe/CdS-quantum rods: fluorescent probes for in vivo two-photon laser scanning microscopy.

CdSe/CdS-Quantum-dots-quantum-rods (QDQRs) with an aspect ratio of ∼ 6 are prepared via the seeded growth method, encapsulated within a shell of crosslinked poly(isoprene)-block-poly(ethylene glycol) (PI-b-PEG) diblock copolymer, and transferred from the organic phase into aqueous media. Their photoluminescence quantum yield (PLQY) of 78% is not compromised by the phase transfer. Within a perio...

Folic acid-functionalized mesoporous silica nanospheres hybridized with AIE luminogens for targeted cancer cell imaging.

Fluorescent nanoparticles (FNPs) have been found to be useful as visualization tools for biological sensing, probing, imaging, and monitoring. Applied to targeted cancer cell imaging, FNPs are highly desirable for early stage cancer diagnosis and treatment. However, the light emission from most of the FNPs reported is severely limited because of the aggregation-caused quenching (ACQ) effect. He...
