Fluorescent Tracer Transport in Engineered Vasculature Under Pressure Actuation

Figshare hosts video data depicting fluorescent dextran transport within collagen hydrogels under constant or pulsatile pressure actuation. Daniel Alcaide Martín created this collection of AVI files, which was last updated in April 2026. The 43.3 MB dataset visualizes solute clearance differences between acellular and vascularized channel configurations.

Use Cases

• Analyze tracer displacement patterns in AVI videos to compare clearance rates between pulsatile and constant pressure conditions.
• Quantify the 1.3-fold faster tracer clearance in vascularized devices under pulsatile actuation versus constant actuation.
• Study the mechanisms of solute evacuation, such as ejection through central channels or lateral displacement, visible in the video frames.
• Model strain accumulation-release dynamics in soft materials by observing fluorescent dextran transport in hydrogel environments.

Strengths

• Data directly visualizes a key experimental finding: pulsatile actuation produced 1.3-fold faster tracer clearance in vascularized devices.
• Videos are provided in a standard AVI format, facilitating frame-by-frame analysis of transport phenomena.
• Dataset has a clear open license (CC-BY-4.0) permitting reuse and redistribution.

Limitations

• Dataset is small at 43.3 MB, limiting the scope for large-scale machine learning model training.
• No accompanying quantitative data (e.g., columnar measurements) is provided, restricting analysis to manual video inspection.
• The experimental scope is narrow, focusing on a specific hydrogel and tracer setup, which may limit generalizability.
