Data for publication: Creation of a 3D goethite–spongin composite using an extreme biomimetics approach

The dataset includes:FTIR Raw data of FTIR spectra of the samples: control sample, FeISpongin, and a goethite standard.XRD Raw data of XRD patterns of spongin, control sample, FeISpongin composite, and goethite standard.TG Raw data of thermogravimetric (TG) curves of control sample, FeISpongin composite, and goethite standard.Raw_data_dopamine_detection Raw data of Amperograms recorded in 0.1 M phosphate buffer pH 6.5 with the successive addition of DA (5 μM to 1.3 mM) at Natural-Fe-Spongin/CPE and FeISpongin/CPE. The data are part of the publication: Kubiak, A.; Voronkina, A.; Pajewska-Szmyt, M.; Kotula, M.; Leśniewski, B.; Ereskovsky, A.; Heimler, K.; Rogoll, A.; Vogt, C.; Rahimi, P.; et al.
