Schematic diagrams showing the Ln-DNA DX lattice fabrication process and the Raman spectra and AFM images of Ln-DNA with various concentrations of lanthanide ions.

(a) Schematic diagrams of Ln-DNA DX lattice fabrication. (b) Raman spectra of DNA and Gd-DNA with 0.5, 1.0 and 2.0 mM of Gd3+ ions. (c) AFM images of pristine DNA and Gd-DNA with 0.5 and 2.0 mM Gd3+. Inset: Noise-filtered 2D spectrum images constructed by Fast Fourier Transform showing a crystalline nature with clear periodicity of DNA lattices with 0.5 mM of Gd3+ and an amorphous nature without periodicity of DNA with 2.0 mM of Gd3+.
