Fluorescence Origin of Nanodiamonds

The Journal of Physical Chemistry C, 2015
Despite extensive work on the fluorescence behavior of graphite and graphene quantum dots, reports on the luminescence of nanodiamonds are so far much fewer. In fact, nanodiamonds are distinctly different from carbon quantum dots with nondiamond phases in both crystalline structure and electronic structure.

Functionalized Fluorescent Nanodiamonds for Biomedical Applications

Nanomedicine, 2008
In recent years, carbon and carbon-based nanomaterials have received increasing attention for applications in life sciences. Nanodiamond (ND) stands out as a unique new substance in these applications because it holds several momentous properties such as good biocompatibility, excellent photostability and facile surface functionalizability. A number of

Fluorescent nanodiamonds for biological applications

2011 International Quantum Electronics Conference (IQEC) and Conference on Lasers and Electro-Optics (CLEO) Pacific Rim incorporating the Australasian Conference on Optics, Lasers and Spectroscopy and the Australian Conference on Optical Fibre Technology, 2011
Biomedical imaging often involves the use of fluorophores, bright optical labels which enable observation of objects which are otherwise invisible. Conventional fluorophores include fluorescein, rhodamine, fluorescent proteins and quantum dots; however, often these are limited by cytotoxicity, pH sensitivities, brightness or photo bleaching/blinking [1]

Fluorescent nanodiamonds for ultrasensitive detection

SPIE Proceedings, 2014
Fluorescent nanodiamonds (NDs) are new and emerging nanomaterials that have potential to be used as fluorescence imaging agents and also as a highly versatile platform for the controlled functionalization and delivery of a wide spectrum of therapeutic agents.

Multicolor fluorescent nanodiamonds for bioimaging

Biophotonics Australasia 2019, 2019
Fluorescent nanodiamonds made from high-pressure high-temperature diamond are increasingly used in biological imaging and sensing applications. To date, only red and green fluorescent nanodiamonds are widely available, severely limiting nanodiamond-based multiplexed imaging.

Temperature-dependent fluorescence in nanodiamonds

Applied Physics Express, 2017
Here, we report that nanodiamonds (NDs) exhibit blue fluorescence with an emission peak at around 400 nm. With increasing temperature, the peak energy of fluorescence was found to demonstrate a blue shift, possibly due to excited excitons populating higher-energy states, such as oxidation defect states.

Charge-sensitive fluorescent nanosensors created from nanodiamonds

Nanoscale, 2015
Direct optical detection of charge changes caused by noncovalent chemical events in the vicinity of the nanodiamond surface was achieved. This finding opens new possibilities for construction of biocompatible and extremely photostable two-color fluorescent (bio)nanosensors.

Fluorescent Glyco Single-Chain Nanoparticle-Decorated Nanodiamonds

ACS Macro Letters, 2017
We introduce the light-induced collapse of single glycopolymer chains in water generating fluorescent glyco single-chain nanoparticles (SCNPs) and their subsequent functionalization onto nanodiamonds. The glycopolymer precursors are prepared by polymerizing an acetylated mannose-based methacrylate monomer followed by a deprotection and ...

Fluorescent Nanodiamonds from Molecular Diamond Seed

CLEO: 2015, 2015
We present a new materials growth technique using diamondoid molecular diamonds as a seed for chemical vapor deposition growth. We show that both nanoscopic high quality diamond crystals with silicon vacancy color centers can be grown from self-assembled monolayers of pentamantane (C26H32).

Fluorescent Nanodiamonds: Effect of Surface Termination

MRS Proceedings, 2009
AbstractIt has been reported that physico-chemical properties of diamond surfaces are closely related to the surface chemisorbed species on the surface. Hydrogen chemisorption on a chemical vapor deposition grown diamond surface is well-known to be important for stabilizing diamond surface structures with sp3 hybridization.
