A handheld high-sensitivity micro-NMR CMOS platform with B-field stabilization for multi-type biological/chemical assays [PDF]
, 2016 We report a micro-nuclear magnetic resonance (NMR) system compatible with multi-type biological/chemical lab-on-a-chip assays. Unified in a handheld scale (dimension: 14 x 6 x 11 cm³, weight: 1.4 kg), the system is capable to detect<100 pM of ...

Ultrafast Z-Spectroscopy for 129Xe NMR-Based Sensors [PDF]
The Journal of Physical Chemistry Letters, 2013 When working with hyperpolarized species, it is often difficult to maintain a stable level of magnetization over consecutive experiments, which renders their detection at the trace level cumbersome, even when combined with chemical exchange saturation transfer (CEST).

129Xe NMR-Protein Sensor Reveals Cellular Ribose Concentration [PDF]
Analytical Chemistry, 2020 Dysregulation of cellular ribose uptake can be indicative of metabolic abnormalities or tumorigenesis. However, analytical methods are currently limited for quantifying ribose concentration in complex biological samples. Here, we utilize the highly specific recognition of ribose by ribose-binding protein (RBP) to develop a single-protein ribose sensor ...
