Research-Spotlight - Dr Ken Leung along with his research collaborative team conducted a study highlighting the surface-directed orientational assemblies process and versatile applications of Janus nanosheets.

Janus, amphiphilic and amphichiral nanosheets are two-dimensional materials composed of two distinct phases and having both hydrophobic and hydrophilic regions. These amphiphilic nanosheets have different properties on each side, allowing for versatile applications. The term “Janus” originates from the Roman god with two faces, symbolizing the dual nature of these nanosheets. Janus nanosheets can be utilized as dual substrate carriers due to their unique biphase structure. The distinct properties of each side can be tailored to undergo “Surface-Directed Orientational Assemblies”, enabling selective substrate release and unique chiral optical properties. Dual release of selected substrates ex vivo could be achieved by the same materials and successfully characterized by mass spectrometric imaging. Dr Ken LEUNG, Associate Professor of the Department of Chemistry at Hong Kong Baptist University (HKBU), along with his research collaborative team with Professor Albert CHAN (former President of HKBU), Dr Jianing WANG, Professor Tao ZENG and Professor Zongwei CAI of the State Key Laboratory of Environmental and Biological Analysis, as well as Professor Zhifeng HUANG from the Department of Chemistry at The Chinese University of Hong Kong, conducted a study highlighting the surface-directed orientational assemblies process and versatile applications of Janus MoS2 nanosheets.
