Carbon Dots for Multiphoton Bioimaging [PDF]

open access: yesJournal of the American Chemical Society, 2007
Carbon nanoparticles upon simple surface passivation exhibit bright photoluminescence. Reported here is a new finding that these carbon dots are also strongly two-photon luminescent with pulsed laser excitation in the near-infrared. The experimentally measured two-photon absorption cross-sections are comparable to those of the high-performance ...

Synergy between “Probiotic” Carbon Quantum Dots and Ciprofloxacin in Eradicating Infectious Biofilms and Their Biosafety in Mice

open access: yesPharmaceutics, 2021
Orally administrated probiotic bacteria can aid antibiotic treatment of intestinal infections, but their arrival at their intestinal target site is hampered by killing in the gastrointestinal tract and by antibiotics solely intended for pathogen killing.

Control of photoluminescence of carbon nanodots via surface functionalization using para-substituted anilines [PDF]

open access: yes, 2018
Carbon nanodots (C-dots) are a kind of fluorescent carbon nanomaterials, composed of polyaromatic carbon domains surrounded by amorphous carbon frames, and have attracted a great deal of attention because of their interesting properties. There are still,

Carbon Nanodots as Peroxidase Nanozymes for Biosensing

open access: yesMolecules, 2016
‘Nanozymes’, a term coined by Scrimin, Pasquato, and co-workers to describe nanomaterials with enzyme-like characteristics, represent an exciting and emerging research area in the field of artificial enzymes.

Carbon Dots: Excitation‐Dependent Photoluminescence from Single‐Carbon Dots (Small 48/2017) [PDF]

open access: yesSmall, 2017
In article 1702098, by Bart van Dam, Minjie Li, and co‐workers, single‐dot spectroscopy is used to show that individual carbon dots already exhibit excitation‐dependent photoluminescence, very similar to the ensemble of carbon dots. Characteristic excitation‐dependent emission spectra are identified, indicating the presence of multiple active emission ...

Electrochemical Synthesis of Carbon Quantum Dots

open access: yesChemElectroChem, 2023
AbstractCarbon quantum dots (CDs) are “small” carbon nanostructures with excellent photoluminescence properties, together with low‐toxicity, high biocompatibility, excellent dispersibility in water as well as organic solvents. Due to their characteristics, CDs have been studied for a plethora of applications as biosensors, luminescent probes for ...

Double Quantum Dots in Carbon Nanotubes

open access: yes, 2010
We study the two-electron eigenspectrum of a carbon-nanotube double quantum dot with spin-orbit coupling. Exact calculation are combined with a simple model to provide an intuitive and accurate description of single-particle and interaction effects.
