Pill Millipede Exoskeleton NMR Spectra and AFM Topography

Solid-state Nuclear Magnetic Resonance (NMR) spectroscopy and Atomic Force Microscopy (AFM) data characterize the chemical structure and surface morphology of the pill millipede Arthrosphaera lutescens. The NMR data includes ¹³C and ³¹P cross-polarization magic angle spinning (CP-MAS) spectra acquired at 500 MHz with 10 kHz MAS frequency and SPINAL64 decoupling. AFM data comprises raw scans and processed 2D/3D topographical images of the seventh dorsal tergite, captured in tapping mode with a silicon nitride cantilever at 256x256 pixel resolution.

Use Cases

• Analyzing exoskeleton biomineralization and polymer composition based on ¹³C and ³¹P CP-MAS NMR spectra.
• Quantifying surface roughness and microstructural features from processed AFM topographical images.
• Correlating chemical composition with physical surface properties for biomimetic material design.
• Method validation for solid-state NMR techniques (e.g., SPINAL64 decoupling) on biological samples.
• Benchmarking image analysis algorithms for nanoscale topography using provided AFM scan files.

Strengths

• Includes both raw and processed data for NMR and AFM, supporting reproducibility.
• AFM parameters are precisely documented, including cantilever type (Si₃N₄), resonant frequency (235 kHz), and scan resolution (256x256 pixels).
• Dataset is cross-platform and openly licensed under CC-BY-4.0.

Limitations

• Column names and row counts are not provided, limiting immediate understanding of data structure.
• The temporal coverage and sample collection dates are not specified.
• The dataset size (60.4 MB) is provided, but the exact number of files or spectra is unclear.
