    Sugar alcohol provides imaging contrast in cancer detection
  2. 262
    “…However, the highly repetitive nature of the LRP reporter gene sequence leads to DNA recombination events and the expression of a range of truncated LRP protein fragments, thereby greatly limiting the CEST sensitivity. Here we report the use of a redesigned LRP reporter (rdLRP), aimed to provide excellent stability and CEST sensitivity. …”

    “…In 2015, we reported picomolar detection of commercially available CB[6] via hyper-CEST. Inspired by the versatile host–guest chemistry of CB[6], our lab and others developed “turn-on” strategies for CB[6]-hyper-CEST biosensing, demonstrating detection of protein analytes in complex media and specific chemical events. …”

    “…Detection of bare gas microbubbles by magnetic resonance (MR) at low concentrations typically used in clinical contrast‐ultrasound studies was recently demonstrated using hyperCEST. Despite the enhanced sensitivity achieved with hyperCEST, in vivo translation is challenging as on‐resonance saturation of the gas‐phase core of microbubbles consequently results in saturation of the gas‐phase hyperpolarized (129)Xe within the lungs. …”
