Contact-Free Mechanical Mapping of 3D Microprinted Hydrogels using FLIM

A dataset from heiDATA Harvested Dataverse presents raw data for mapping the mechanical properties of microscale 3D printed hydrogel microstructures. The data includes fluorescence-lifetime imaging microscopy (FLIM) data, Raman spectroscopy data, nanoindentation load–displacement curves, and microscopy images. It was authored by Eivgi, Or and last updated on May 31, 2026.

Use Cases

• Correlating autofluorescence lifetime signals with mechanical properties based on FLIM and nanoindentation data.
• Studying the effect of printing laser dose on material properties based on the described variation from 1.0 ns to 3.0 ns.
• Investigating irreversible changes from hydration cycles based on data on dehydration and rehydration effects.
• Validating contact-free mechanical mapping techniques for soft materials like PEG-based hydrogels.

Strengths

• Dataset contains four distinct, complementary data types: FLIM, Raman spectroscopy, nanoindentation curves, and microscopy images.
• Mechanical property range is quantified, with stiffness spanning a narrow range between 3 and 5 MPa.
• Specific fluorescence lifetime values are provided, varying from approximately 1.0 ns to 3.0 ns with laser dose.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file sizes are unknown, which may limit suitability assessment.
• Data appears focused on a specific material (PEG-based hydrogels) and fabrication method (two-photon 3D laser printing), limiting generalizability.
