I am Cheng-Kang Chiang, currently serving as an Associate Professor in the Department of Chemistry at National Dong Hwa University (NDHU). I received my Ph.D. in Chemistry from National Taiwan University in 2010. Following the completion of my doctoral degree, I pursued postdoctoral training at the Ottawa Institute of Systems Biology, University of Ottawa, and at the Children's Hospital of Eastern Ontario in Canada. In 2017, I joined the Department of Chemistry at NDHU, where I currently hold the position of Associate Professor.

With the rapid advancement of nanotechnology, the synthesis of functional nanomaterials (NMs) and the exploration of their potential chemical and biomedical applications have become major highlights in scientific development over the past two decades. In parallel, the application of green chemistry principles for the fabrication of nanoscale materials has attracted extensive attention from the scientific community over the last decade. Our laboratory focuses on the green synthesis of nanomaterials by employing traditional medicinal herbs as bioresources. After extracting their principal bioactive constituents, we utilize these phytochemicals as reducing and stabilizing agents to fabricate broad-spectrum antibacterial nanomaterials with enhanced antimicrobial efficacy. Furthermore, we apply high-resolution mass spectrometry–based approaches to investigate the adaptive and survival mechanisms of bacteria under nanomaterial-induced stress. In addition, we are currently developing spatial mass spectrometry technologies to elucidate the biodistribution and tissue penetration pathways of toxic molecules, thereby advancing our understanding of how these compounds enter the human body and subsequently impact human health.
