In the past decade, a great effort has been devoted to develop new biosensor platforms for the detection of a wide range of analytes. Among the various approaches, magneto-DNA assay platforms have received extended interest for high sensitive and specific detection of targets with a simultaneous manipulation capacity. Here, using nitrogen-vacancy quantum centers in diamond as transducers for magnetic nanotags (MNTs), a hydrogel-based, multiplexed magneto-DNA assay is presented. Near-background-free sensing with diamond-based imaging combined with noninvasive control of chemically robust nanotags renders it a promising platform for applications in medical diagnostics, life science, and pharmaceutical drug research. To demonstrate its potential for practical applications, we employed the sensor platform in the sandwich DNA hybridization process and achieved a limit of detection in the attomolar range with single-base mismatch differentiation.

Acroscyphodysplasia (ASD) is an ultra-rare skeletal dysplasia characterized by severe brachydactyly, metaphyseal scaphoid knee deformities, growth retardation, and intellectual disability. To date, only seven cases of ASD have been reported, all associated with missense variants in the gene. We report a 7-year-old girl with ASD features, including midface hypoplasia, severe growth retardation (-4.

We measured the residual stress tensor in a nitrogen-doped chemical vapor deposition (001) diamond film. The stress tensor was evaluated from the amount of the shift in optically detected magnetic resonance (ODMR) spectra of NV center in the diamond. A confocal microscopy setup was used to observe the spatial variation of the stress tensor in the diamond film.

It is anticipated that wide-bandgap semiconductors (WBGSs) would be useful materials for energy production and storage. A well-synthesized, yet scarcely explored, diamond-like quaternary semiconductor LiZnGeS has been considered for this work. Herein, we have employed two well-known functionals GGA and mGGA within a framework of density functional theory (DFT).

In this study, we unveil a critical function of anions in tailoring the interfacial water coordination environment and electronic structure at the Zn-electrolyte interface. These features thermodynamically hinder water-induced parasitic reactions, enabling highly reversible Zn plating/stripping. And the optimal electrolyte supports high-mass-loading applications in Zn-MnO batteries.

Zero and ultralow-field nuclear magnetic resonance (ZULF NMR) is an NMR modality where experiments are performed in fields at which spin-spin interactions within molecules and materials are stronger than Zeeman interactions. This typically occurs at external fields of microtesla strength or below, considerably smaller than Earth's field. In ZULF NMR, the measurement of spin-spin couplings and spin relaxation rates provides a nondestructive means for identifying chemicals and chemical fragments, and for conducting sample or process analyses.
