Implementation Considerations

• Requires expertise in microfluidic device fabrication, plasma bonding, and syringe pump operation for precise fluid control.
• Depends on access to vacuum desiccators, ovens, plasma generators, and PTFE tubing infrastructure for chip synthesis and fluid delivery.
• Necessitates standardization of flow rate ratios and sheath fluid protocols across teams to ensure reproducible fiber formation and outlet stability.
• Involves adaptation considerations when printing on porous or flexible substrates (e.g., tissue paper, polystyrene) to maintain fiber integrity and structural fidelity.
• Includes practical limitations such as susceptibility to clogging at imbalanced flow rates and the need for acetic acid handling under fume hood conditions.
