Highly biocompatible amphiphilic perylenediimide derivative for bioimaging

Highly emissive and biocompatible dopamine-derived oligomers as fluorescent probes for chemical detection and targeted bioimaging.

We prepared highly emissive and biocompatible dopamine-derived oligomers, and demonstrated their applications as novel fluorescent probes for sensitive detection of Fe(3+) ions and targeted bioimaging in live cells.

Synthesis of biocompatible multicolor luminescent carbon dots for bioimaging applications.

Water-soluble carbon dots (C-dots) were prepared through microwave-assisted pyrolysis of an aqueous solution of dextrin in the presence of sulfuric acid. The C-dots produced showed multicolor luminescence in the entire visible range, without adding any surface-passivating agent. X-ray diffraction and Fourier transform infrared spectroscopy studies revealed the graphitic nature of the carbon and...

Highly luminescent biocompatible Carbon Quantum Dots by encapsulation with an amphiphilic polymer.

Highly luminescent, water-soluble and biocompatible Carbon Quantum Dots (aqCQDs) were prepared by encapsulating the parent hydrophobic CQDs in an amphiphilic polymer. The resulting aqCQDs were non-toxic to living cells, and were found to cross the cell membrane and localise primarily in the cytosol.

1 Synthesis and Spectroscopic Properties of a Novel Perylenediimide Derivative

Forming biocompatible and nonaggregated nanocrystals in water using amphiphilic polymers.

High-quality nanocrystals formed in organic solvents can be completely solubilized in water using amphiphilic copolymers containing poly(ethylene glycol) or PEG. These copolymers are generated using a maleic anhydride coupling scheme that permits the coupling of a wide variety of PEG polymers, both unfunctionalized and functionalized, to hydrophobic tails. Thermogravimetric analysis, size exclu...
