She leads a very dynamic group conducting cutting edge interdisciplinary and innovative research on the design and synthesis of nanomaterials for biomedical applications from diagnostics to treatment of diseases such as cancer. She was appointed a full professor in nanomaterials in 2013 at the Biophysics Group, Department of Physics and Astronomy, University College London, UK. Professor Nguyễn Thi Kim Thanh, FRSC, MInstP (), held a prestigious Royal Society University Research Fellowship (2005–2014). His research interests focus on the use of nanomaterials for biomedical applications. He is currently a postdoctoral fellow at Northwestern University (Evanston, IL). After a year working on the growth of 2D nanomaterials at NTT Basic Research Laboratories (Atsugi, Japan), he started a joint doctoral program between the University College London (UCL, London, UK) and the Agency for Science, Technology and Research (Singapore), obtaining a PhD in materials science from UCL in 2016. Pallares received his BSc and MSc degrees in chemistry from the Ramon Llull University (Barcelona, Spain) in 20, respectively. The variety of nanostructures he prepares are either directed for specific applications or simply inspired from curiosity to explore new protocols and characterize the resulting products. His current research activity involves mostly work on the synthesis and characterization of magnetic nanoparticles. Currently he is working at the University College London (UCL) as a research associate. Apart from his native country, he also worked in post-doctoral projects in France and Spain. We describe the main characteristics of the techniques and their operation principles and we give various examples of their use, presenting them in a comparative mode, when possible, in relation to the property studied in each case.ĭr Stefanos Mourdikoudis is a chemical engineer who obtained his PhD degree from the Department of Physics, Aristotle University of Thessaloniki in Greece in 2009. Different characterization techniques are classified according to the concept/group of the technique used, the information they can provide, or the materials that they are destined for. The principal objective of this review is to summarize the present knowledge on the use, advances, advantages and weaknesses of a large number of experimental techniques that are available for the characterization of nanoparticles. In addition, given that the significance of nanoparticles in basic research and applications is constantly increasing, it is necessary that researchers from separate fields overcome the challenges in the reproducible and reliable characterization of nanomaterials, after their synthesis and further process ( e.g. Different strengths and limitations of each technique complicate the choice of the most suitable method, while often a combinatorial characterization approach is needed. In several cases, there are physical properties that can be evaluated by more than one technique. Several techniques have been used to characterize the size, crystal structure, elemental composition and a variety of other physical properties of nanoparticles. This setup is preferred for small crystals and crystals of compounds containing mostly light atoms (i.e.Nanostructures have attracted huge interest as a rapidly growing class of materials for many applications. Due to the diameter of the incident beam (0.3 mm) the longest dimension of the crystal should be smaller than 0.3 mm. Incoatec microfocus CuK α source (λ= 1.54178 Å) and Photon II detector. ![]() Preferred size of crystals is between 100 nm and 200 nm. Diffracted rays at the correct orientation for the configuration are then collected by the detector. X-Rays are either transmitted through the crystal, reflected off the surface, or diffracted by the crystal lattice. The data generated from the X-ray analysis is interpreted and refined to obtain the crystal structure by single-crystal refinement. Single-crystal X-ray Diffraction, SXRD, is a non-destructive analytical technique which provides detailed information about the internal lattice of crystalline substances, including unit cell dimensions, bond-lengths, bond-angles, as well as site-ordering.
