About
Longxiu Feng is a materials scientist and analytical chemist whose research focuses on the development of novel, low-cost surface-enhanced Raman scattering (SERS) substrates for rapid food safety and environmental monitoring. Her major contributions center on the innovative use of robotic writing to fabricate highly sensitive SERS platforms, moving beyond traditional, labor-intensive methods. In her most cited work, Feng demonstrated the direct robotic deposition of silver ink onto photographic paper, creating a flexible, disposable sensor capable of detecting trace levels of the pesticide thiram in fruit samples—a method that achieved 10 citations for its practical, real-world applicability. She further advanced this approach by optimizing the robotic fabrication of silver nanoparticle-drawing paper substrates, achieving exceptional sensitivity and uniformity (7 citations). By merging precision robotics with nanomaterial engineering, Feng has introduced a scalable, reproducible pathway for point-of-need chemical sensing. Her work bridges the gap between advanced nanophotonics and accessible analytical tools, offering a compelling solution for on-site contaminant detection in agriculture and public health.
