Organic Nanodiamonds

, 2017
Nano-crystalline diamond is a new carbon phase with numerous intriguing physical and chemical properties and applications. Small doped nanodiamonds for example do find increased use as novel quantum markers in biomedical applications. However, growing doped nanodiamonds below sizes of 5 nm with controlled composition has been elusive so far.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Two‐Photon 3D Printing of Functional Microstructures Inside Living Cells

Advanced Materials, EarlyView.
This study demonstrates 3D printing inside living cells by using two‐photon photo‐lithography. A bio‐compatible photoresist is injected into cells and selectively polymerized with a femtosecond laser, creating custom‐shaped intracellular structures with submicron resolution.

Electron spin resonance of nitrogen-vacancy centers in optically trapped nanodiamonds

, 2012
Using an optical tweezers apparatus, we demonstrate three-dimensional control of nanodiamonds in solution with simultaneous readout of ground-state electron-spin resonance (ESR) transitions in an ensemble of diamond nitrogen-vacancy (NV) color centers ...

Tunable Plasmonic Response of Silver Nanoparticles Entangled in Detonation Nanodiamond Network via Colloidal Self‐Assembly

Advanced Materials Interfaces, EarlyView.
Detonation nanodiamonds form a network that entangles silver nanoparticles into stable nanocomplexes. The structure can fine‐tune and enhance plasmonic absorption through nearfield electromagnetic interactions but prevents silver particle aggregation. The study shows how the arrangement and concentration of particles affect light absorption, offering a
