Response to Comment on "Structure-Correlated Magnetic Resonance Transverse Relaxivity Enhancement in Superparamagnetic Ensembles with Complex Anisotropy Landscape".

Y. Gossuin et al. in their Comment on "Structure-Correlated Magnetic Resonance Transverse Relaxivity Enhancement in Superparamagnetic Ensembles with Complex Anisotropy Landscape" [ Langmuir 2023, DOI: 10.1021/acs.langmuir.2c03428] put forward certain concerns about the proposed relaxation dependency hypothesis described in our work [ Langmuir 2022, 38 (36), 11087-11098.]. In this reply to their comment, we would like to express the justification of our considered hypothesis in the complex geometry of nanosystems in order to overcome the raised concerns of MR-relaxivity dependency on such complex landscape of anisotropy.
