Special Issue Information

Dear Colleagues,

Professor Ben Zhong Tang is currently the Dean of the School of Science and Engineering and the X.Q. Deng Presidential Chair Professor at The Chinese University of Hong Kong, Shenzhen (CUHK-SZ). Professor Tang received his BS and Ph.D. degrees from South China University of Technology and Kyoto University in 1982 and 1988, respectively. He conducted his postdoctoral work at the University of Toronto and worked as a senior scientist in Neos Co., Ltd. in 1989–1994. He joined the Hong Kong University of Science and Technology in 1994 and was promoted to Chair Professor in 2008. Professor Tang was elected to the Chinese Academy of Sciences, Asia Pacific Academy of Materials, and the World Academy of Sciences for the Advancement of Science in Developing Countries. He is also the fellows of the Royal Society of Chemistry and the International Union of Societies for Biomaterials Science and Engineering.

Professor Tang has published >1,600 papers. His publications have been cited >131,000 times, with an h-index of 164. He has been listed by Clarivate Analytics as Highly Cited Researcher in both areas of Chemistry and Materials Science since 2014. He received National Natural Science Award (1st Class) from the Chinese Government (2017), Scientific and Technological Progress Award from Ho Leung Ho Lee Foundation (2017), Senior Research Fellowship from Croucher Foundation (2007), etc. He is now serving as Editor-in-Chief of Aggregate published by Wiley. Professor Tang has coined the concept of Aggregation-Induced Emission (AIE) and pioneered the development of the AIE field. Currently, AIE research, including the phenomenon, mechanism, materials, and applications, has been widely conducted in the whole world and has opened a venue to an array of possibilities with great potential for high-tech innovations.

Gram-negative bacteria are difficult to kill due to their complex cell envelope, including the outer membrane (OM) and cytoplasmic membrane (CM). To monitor the membranolytic action of antimicrobials on Gram-negative bacteria would facilitate the development of effective antimicrobials. In this paper, an aggregation-induced emission luminogen (AIEgen) with microenvironment-sensitive properties was employed to indicate the interaction of antimicrobials with the OM and CM of Gram-negative bacteria. The damaged extent of OM and CM caused by antimicrobials with the change of dosage and incubation time can be visually captured based on the variation of two emission colors of IQ-Cm responding to OM-defective (green) and CM-disruptive bacteria (orange). Meanwhile, the activity assessment of antimicrobials can be easily realized within 1~2 h based on the distinct response of IQ-Cm to live and dead E. coli, which is much faster than the agar plate culture. This probe may shed light on the understanding of the interaction between the membrane-active antimicrobials and cell envelope of Gram-negative bacteria and contribute to the future development of antimicrobials.

TiO2-based ultraviolet photodetectors have drawn great attention and are intensively explored. However, the construction of TiO2-based nanocomposites with excellent ultraviolet responses remains challenging. Herein, a TiO2 nanorod array was successfully prepared on fluorine-doped tin oxide (FTO) conductive glass by a one-step hydrothermal method. Then, polypyrrole (PPy)-TiO2 nanorod array composites were designed via subsequent in situ oxidative polymerization. The morphologies, structures, and photocurrent responses of the nanocomposites were systematically investigated. The results demonstrated that polypyrrole-TiO2 exhibited a stronger photocurrent response than pure TiO2 due to the p-n junction formed between n-type TiO2 nanorod arrays and p-type polypyrrole. The PPy-TiO2 composite obtained by deposition three times had the best photoelectric properties, exhibiting good performance with a sensitivity of 41.7 and responsivity of 3.5 × 10−3 A/W. Finally, the mechanism of the photoelectrical response of PPy-TiO2 composites was discussed, guiding the design of high-performance TiO2-based ultraviolet photodetectors. Full article

Hepatocellular carcinoma (HCC) is a malignant tumor with high morbidity and mortality on a global scale, and the development of accurate detection and imaging methods for HCC cells is urgently needed. Herein, by connecting peptide L5, which can specifically bind to the overexpressed Glypican-3 (GPC-3) protein of HCC cells with aggregation-induced emission (AIE) moiety ammonium cation-functionalized 9,10-distyrylanthracene (NDSA) via the “click” reaction, we synthesized a fluorescent probe NDSA-L5. In an aqueous solution, the probe shows weak emission, whereas, in the presence of the GPC-3 protein, bright fluorescence can be obtained since NDSA-L5 binds to the GPC-3 protein, leading to the restricted intramolecular movement of AIE-active NDSA-L5. The imaging and flow cytometry experiments demonstrate that the NDSA-L5 probe can rapidly accumulate in the subcutaneous HCC cells and liver tumor tissue and shows a potential application in early detection and surgical navigation for HCC cancer.

Information encryption and anti-counterfeiting play an important role in many aspects of daily life, such as in minimizing economic losses, protecting secure communication and public security, and so on. Owing to the high information capacity and ease of operation, luminescent materials for advanced information encryption and anti-counterfeiting are essential to meet the increasing demand on encryption security. Herein, we summarize two emerging luminescent materials for information encryption and anti-counterfeiting—AIE materials and room-temperature phosphorescent materials. Finally, we discuss the opportunities and anticipations of these two information encryption and anti-counterfeiting materials. Full article

Bioluminescent analysis of adenosine triphosphate (ATP) concentrations is now acquiring new applications in the form of objects and processes in which it can be effectively used for sensing. A quick analysis of biological objects and systems for which the level of ATP concentrations is one of the main parameters, and a forecast of the development of various situations in such biosystems under industrial production conditions or the ecological state of the environment, confirmed by various results of analytical control of other parameters, turns out to be simple and effective. Sanitary control, quality control of purified water, microbial analysis in the food industry, maintenance of drugs and estimation of their quality, and monitoring of the metabolic state of biocatalysts used in various biotechnological processes are between the main trends of recent applications of bioluminescent ATP-assay. Additionally, the new areas of ATP sensing are developed, and the following topics are their creation of synthetic microbial consortia, their introduction as new biocatalysts to biodegradation of pesticides, suppression of methane accumulation in model urban land fields, control of dangerous development of biocorrosive processes, design of chemical-biocatalytic hybrid processes, creation of effective antimicrobial dressing and protective tissue materials, etc. These aspects are the subject of this review.
