Professor Yoon-Seok Chang's research lab specializes in environmental biotechnology and green chemistry, focusing on the enzymatic and nanomaterial-mediated transformation of natural compounds for sustainable applications. The lab investigates laccase enzymes and their role in catalyzing the polymerization of phenolic compounds for eco-friendly applications such as natural hair dyes and biopolymer synthesis. It also explores the physiological and biochemical impacts of nanoscale zerovalent iron (nZVI) on plants, aiming to enhance agricultural sustainability through nanomaterial-driven plant growth promotion. The overarching research direction emphasizes the development of environmentally benign technologies using biological and nanomaterial systems.

Laccases are oxidases that contain several copper atoms, and catalyse single-electron oxidations of phenolic compounds with concomitant reduction of oxygen to water. The enzymes are particularly widespread in ligninolytic basidiomycetes, but also occur in certain prokaryotes, insects and plants. Depending on the species, laccases are involved in various biosynthetic processes contributing to carbon recycling in land ecosystems and the morphogenesis of biomatrices, wherein low-molecular-weight na
Nanoscale zerovalent iron (nZVI) is the most widely used nanomaterial for environmental remediation. The impacts of nZVI on terrestrial organisms have been recently reported, and in particular, plant growth was promoted by nZVI treatment in various concentrations. Therefore, it is necessary to investigate the detailed physiological and biochemical responses of plants toward nZVI treatment for agricultural application. Here, the effects of nZVI on photosynthesis and related biochemical adaptation
