Smart Polymeric 3D Microscaffolds Hosting Spheroids for Neuronal Research via Quantum Metrology
Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.Development of a platform consisting of 3D microscaffolds supporting 3D embryoid bodies for neuronal research. The polymeric scaffolds enable directed growth of neurites. This study shows nanodiamond‐based quantum sensors graft onto the polymer material, enabling quantum metrology experiments within the 3D neuronal model and thereby providing a ...

Small, Volume 21, Issue 5, February 5, 2025.The complex charge carrier dynamics of promising carbon nitride photocatalysts make optimization challenging. Here spatial heterogeneity is discovered using transient absorption microscopy on carbon nitride particles from the same synthetic batch. This indicates that there are at least two distinct defect types that control the charge carrier dynamics,

Programmable Activation of Quantum Emitters in High‐Purity Silicon with Focused Carbon Ion Beams
Advanced Quantum Technologies, Volume 8, Issue 1, January 2025.Here, a carbon source for focused ion beams is developed and utilized for the simultaneous creation of two types of quantum emitters in silicon, the W and G centers. Furthermore, a multi‐step implantation protocol is applied for the programmable activation of the G centers with a spatial resolution better than 250 nm. This approach provides a route for
