Case Study: Polymeric Lattice Microstructure-Based MNA (PL-pMNA)
Dervisevic et al. developed a PL-pMNA balancing coverage with structural stability for transdermal electrochemical biosensing, featuring an Au-coated polymeric MNA with a free-standing polymeric lattice membrane. This design achieved robust piercing without sacrificing spacing uniformity.
Challenge: Balancing MNA coverage with structural stability and protecting biosensing surfaces.
Solution: Developed PL-pMNA with a 4x4 layout, 800 µm pitch, 600 µm MN height, and an approximately 730 µm PL membrane with diamond micro-openings.
Outcome: Achieved robust piercing, enhanced biosensing surface protection, and reliable penetration.
Resolution Achieved by 2PP
Two-photon polymerization (2PP) enables extremely fine feature fabrication critical for microneedle sharpness and internal features.
