Summary:The development of two-dimensional (2D) inorganic materials-based quantum dots (QDs) is still in its infancy but is triggering immense enthusiasm due to their high chemical stability, good aqueous dispersibility, excellent optical property, good biocompatibility and easy functionalization. This review covers almost all the extant 2D-QDs based on graphene, phosphorene, silicene, carbides, nitrides, transition metal dichalcogenide, transition metal oxides and MXenes, etc. Their categories, synthetic routes, properties, functionalization and applications are critically highlighted. In the application section, special emphasis is placed on the progress in bioimaging, cancer therapy, fluorescent sensing and optoelectronics. Meanwhile, the latest advances in 2D QDs-based catalysis and energy since 2015 are addressed. Moreover, 2D nanoclusters, in particular 2D-QDs, are also included. This review provides guidance for 2D-QDs studies to meet the increasing demands in the many diverse applications. This review critically summarizes recent progress in the categories, synthetic routes, properties, functionalization and applications of 2D materials-based quantum dots (QDs).
Bibliography:Dr Yuanhong Xu is currently a professor at Qingdao University, China. She received her PhD in Analytical Chemistry from the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences (2009) working with Prof. Erkang Wang. From 2010 to 2011, she obtained the "Humboldt Research Fellowship for Postdoctoral Researchers" and did postdoctoral research in Prof. Hermann Wätzig's group at TU Braunschweig, Germany. She joined Qingdao University in Oct 2014. Her current scientific interests are in designing quantum dots from two-dimensional materials for biosensors, fluorescent imaging and catalysis. She has published over 70 papers in peer-reviewed journals for an H-index of 20.
Dr Shaojun Guo is currently a professor at the College of Engineering, Peking University. He received his BSc from Jilin University (2005) and PhD from the Chinese Academy of Sciences (2011). He then joined Brown University as a postdoc (2011-2013) and then moved to Los Alamos National Laboratory as a J. Robert Oppenheimer Distinguished Fellow (2013-2015). He has received numerous prestigious prizes, including World Highly Cited Researchers (2014, 2015, 2016) and the ISE-Elsevier Prize for Applied Electrochemistry, etc. He has published over 200 papers in peer-reviewed journals with >18 000 citations (H-index: 70). His research interests are in engineering nanocrystals for catalysis, renewable energy, biosensors and bioimaging.
