A compact and highly fluorescent orange-emitting polymer dot for specific subcellular imaging.
نویسندگان
چکیده
We demonstrate a new compact CN-PPV dot, which emits in the orange wavelength range with high brightness. The small particle size, high brightness, and the ability to highly specifically target subcellular structures make the CN-PPV dots promising probes for biological imaging and bioanalytical applications.

Highly luminescent, fluorinated semiconducting polymer dots for cellular imaging and analysis.
A highly fluorescent fluorinated semiconducting polymer dot (Pdot) with a quantum yield of up to 49% was developed. The fluorinated Pdot was eight times brighter in cell-labeling applications than its non-fluorinated counterpart, and was rod shaped rather than spherical.
متن کاملCyan-emitting and orange-emitting fluorescent proteins as a donor/acceptor pair for fluorescence resonance energy transfer.
GFP (green fluorescent protein)-based FRET (fluorescence resonance energy transfer) technology has facilitated the exploration of the spatio-temporal patterns of cellular signalling. While most studies have used cyan- and yellow-emitting FPs (fluorescent proteins) as FRET donors and acceptors respectively, this pair of proteins suffers from problems of pH-sensitivity and bleeding between channe...
متن کاملA long-wavelength quantum dot-concentric FRET configuration: characterization and application in a multiplexed hybridization assay.
Quantum dot-based concentric Förster resonance energy transfer (cFRET) is a promising modality for the development of multifunctional fluorescent probes for bioanalysis and bioimaging. To date, the scope of cFRET has been largely limited to a prototypical configuration with a particular combination of quantum dot (QD) and fluorescent dyes linked through peptides. Expansion of the scope of cFRET...
متن کاملSub - 1100 nm lasing from post - growth intermixed InAs / GaAs quantum - dot lasers
Impurity free vacancy disordering induced highly intermixed InAs/ GaAs quantum-dot lasers are reported with high internal quantum efficiency (>89%). The lasers are shown to retain the device characteristics after intermixing and emitting in the important wavelength of ∼1070–1190 nm. The non-coated facet Fabry-Pērot post-growth wavelength tuned lasers exhibits high-power (>1.4W) and high-gain (∼...
متن کاملIn Vivo Cancer Targeting and Imaging-Guided Surgery with Near Infrared-Emitting Quantum Dot Bioconjugates
Early detection and subsequent complete surgical resection are among the most efficient methods for treating cancer. However, low detection sensitivity and incomplete tumor resection are two challenging issues. Nanoparticle-based imaging-guided surgery has proven promising for cancer-targeted imaging and subsequent debulking surgery. Particularly, the use of near infrared (NIR) fluorescent prob...
