We report what we believe is the first use of 19F NMR spectroscopy to directly measure in-vitro release (IVR) from polymeric nanoparticles (PNPs). Using 19F NMR we selectively measured IVR of AZD2811 from PNPs. Due to rapid nuclear relaxation in solid-like environments only AZD2811 in solution is detected, and physical separation from the PNPs isn't required. The NMR approach and ultra-centrifugation/UHPLC were shown to be equivalent. The selectivity of 19F NMR means it is readily applied to complex IVR media such as recombinant human serum albumin (rHSA). |
