Abstract
The sensitivity of conventional NMR is limited to metabolites at mid-micromolar concentrations, however diagnostically relevant metabolites are often found at lower concentrations. nh-PHIP has shown promise for analyzing complex biological samples like urine, but adapting it to blood presents additional challenges due to its complex matrix. Herein we successfully demonstrate the use of nh-PHIP for detecting adenine phosphonucleotides in blood.
