Dr. Nancy Willian is a chemistry lecturer and researcher at Universitas Maritim Raja Ali Haji, Indonesia, specializing in the green synthesis of inorganic nanomaterials using coastal bioresources. Her research explores Sargassum spp., the seagrass Enhalus acoroides, and mangrove species, including Rhizophora stylosa, Ceriops tagal, and Xylocarpus granatum. A central focus is the use of extracts from marine and coastal plants as natural reducing and stabilizing agents, replacing conventional chemical reagents in nanoparticle synthesis. This approach aims to minimize hazardous chemical use and waste generation, supporting more environmentally responsible production of silver and gold nanoparticles. Her work also investigates mangrove-derived pigments for natural dyes and ecoprint textiles, connecting coastal biodiversity with materials innovation and opportunities for coastal livelihoods.
Building on this expertise, she is expanding her research into selenium nanoparticles as micronutrient supplements in fish feeds, investigating their potential to support antioxidant defenses, fish health, and nutrient utilization. From a restorative aquaculture perspective, her research explores how improved nutrition and feed efficiency could reduce resource demands and nutrient losses into surrounding waters. By integrating green synthesis, coastal plant resources, and aquaculture nutrition, she seeks to develop technologies that support productive aquaculture while safeguarding coastal ecosystems, with environmental benefits assessed through waste reduction, nutrient retention, and ecological safety.
