Quantum chemistry study of molecular structure and vibrational spectrum of naproxen

Novel dehydropeptide-based magnetogels containing manganese ferrite nanoparticles as antitumor drug nanocarriers

“…This rise in intensity could be related to an increase of dipolar moments variation induced by the MnFe 2 O 4 nanoparticles, while differences in intensity ratios indicate that structural or physicochemical changes occur in the presence of nanoparticles. Wavenumbers were assigned according to previous studies involving naproxen and free amino acids 48,49 (Table S1 in Supplementary Information). , which can be identified as the C-N vibration, suggesting that some interactions might have taken place between the arginine side chain and the magnetic nanoparticles, thus supporting the stronger quenching previously observed in fluorescence assays.…”
