Leveraging high-resolution 3D printing, we are redefining how treatments are administered, enhancing patient comfort, and driving better health outcomes. Our innovative microneedle array platform integrates real-time biomarker monitoring with controlled drug delivery, transforming disease prevention, treatment, and personalized medicine. By replacing traditional blood draws with painless, minimally invasive, and cost-effective 3D-printed microneedle patches, we enable biomarker sampling from interstitial fluid (ISF)—a rich source of molecular information comparable to blood. Beyond diagnostics, this microarray platform enables targeted, needle-free delivery of vaccines and therapeutics into the intradermal space, offering a scalable and adaptable approach to vaccination and treatments. Our goal is to advance precision health by making continuous monitoring and proactive care more accessible, beyond a hospital setting.
