Abstract
Hollow polymer microneedles (MNs), fabricated using two-photon polymerization (TPP), offer a painless means of penetrating the skin for interstitial fluid (ISF) extraction, enabling next-generation health mon-itoring. Integrated with a silicon-based microfluidic chip, the resulting wearable patch ensures consistent ISF sampling, mechanical durability, and biocompatibility—confirmed through both in vivo studies and surrogate testing. The system enables continuous biomarker monitoring for up to 72 hours without caus-ing skin irritation or damage, highlighting its suitability for minimally invasive health applications.
