Prof. Dramićanin has published 1 book, 7 book chapters, and 229 papers in international journals (including papers in the high impact factor journals such as Advanced Materials and ACS Nano). According to Google scholar his papers are cited more than 4800 times. He is leading Optical Materials and Spectroscopy Group () and his research is mainly focused on the synthesis and characterization of lanthanide and transition metal ion activated phosphors and nanophosphors, photocatalytic materials, and physical and chemical sensing using luminescence and luminescent nanoprobes.报告摘要：Temperature sensors comprise a market of USD 5.13 billion and are used across a broad spectrum of human activities, such as in medicine, home appliances, meteorology, agriculture, industry, and military . A significant growth in demand is expected in the near future for contactless temperature sensors, which are not only easy to use, but are less complex and more accurate than contact temperature sensors. For example, there is an immediate need for noncontact thermometry for moving objects or objects which are sensitive to contact, difficult to access, or in hazardous locations . Thermometry based on changes in the optical properties of materials is considered a promising route to meet these needs. Besides the well-known pyrometers and radiation thermometers, of interest are novel optical thermometers based on near-field scanning optical microscopy, Raman scattering, optical interferometry, thermoreflectance, and luminescence spectroscopy. The largest attention among emerging optical methods is in the luminescence thermometry because of the ease of detection of luminescence signal in comparison to other methods, relatively fast response, and a good spatial resolution.This contribution presents the state-of-the art applications of luminescence thermometry, giving a detailed explanation of luminescence spectroscopic schemes for the read-out of temperature . Schemes are classified to as time-integrated and time-resolved ones depending on the temporal nature of the luminescence measurements. The former includes methods based on reading temperatures from the intensity of emission, the ratio of emission intensities, the changes of excitation and emission band positions and widths with temperature, and luminescence anisotropy (polarization). The later includes methods based on measurements of emission decay -times and rise -times. The contribution also presents a comparative analysis of the advantages/disadvantages between of time-integrated and time-resolved temperature read-outs. Examples of temperature read-out schemes are given for different types of materials including phosphors, quantum dots, organic dyes, and luminescent polymers.References: M. D.

报告题目：Microphysiological Systems for Emulating Human Tissues and Diseases报 告 人：Shrike Yu Zhang博士（哈佛大学医学院布莱根妇女医院）时 间：2018年8月30日下午15:00地 点：华南软物质科学与技术高等研究院324报告厅材料科学与工程学院华南软物质科学与技术高等研究院2018年8月28日报告摘要：Microphysiological systems are microfluidic three-dimensional miniature human tissue and organ models that recapitulate the important biological and physiological parameters of their in vivo counterparts. They have recently emerged as a viable platform for personalized medicine and drug screening. These biomimetic organoids are anticipated to replace the conventional planar, static cell cultures, and to bridge the gaps between the current pre-clinical animal models and the human body. In addition, multiple organoids may be channeled together through the microfluidics in a similar manner they arrange in vivo, providing the capacity to analyze interactions among these models. In this talk, I will discuss our recent efforts on developing integrated multi-organ-on-a-chip platforms formed by sophisticated microfluidics and bioengineered organoids, which can operate in a continual and automated manner over extended periods. I will also discuss a series of bioprinting strategies including sacrificial bioprinting, microfluidic bioprinting, and multi-material bioprinting, along with various cytocompatible bioink formulations, for the fabrication of biomimetic organoids. These platform technologies will likely provide new opportunities in constructing functional tissue and disease models with a potential extension into clinical therapeutics and precision therapy.报告人简介：Dr. Zhang received a B.Eng. in Biomedical Engineering from Southeast University, China in 2008, after which he then obtained a M.S. in Biomedical Engineering from Washington University in St. Louis and a Ph.D. in Biomedical Engineering at Georgia Institute of Technology and Emory University School of Medicine . Dr. Zhang then pursued postdoctoral training atBrigham and Women’s Hospital,Harvard Medical School, Harvard-MIT Division of Health Sciences and Technologies, and Wyss Institute for Biologically Inspired Engineering.Dr. Zhang is currently a Research Faculty at Harvard Medical School and Associate Bioengineer at the Brigham and Women’s Hospital. Dr. Zhang’s research is focused on innovating medical engineering technologies, including 3D bioprinting, organs-on-chips, microfluidics, biomedical imaging, and biosensing, to recreate functional tissues and their biomimetic models.
