Feb 2012 - Dr Liu Bin and her team have recently developed a novel class of organic luminogens whose fluorescence emissions are induced by aggregation. This extraordinary aggregationinduced- emission (AIE) feature exploits aggregation-caused quenching (ACQ) that plagues current nanoparticlebased systems used in bioimaging. The newly developed organic nanoparticles have shown low cytotoxicity, high photostability and can be customised to target specific analytes. The subsequent successful demonstration of the AIE-active fluorogen-loaded BSA nanoparticles for FR/NIR imaging of targeted tumors in living bodies could advance research in the field of cancer diagnosis. This paper was featured on the cover of the Advanced Functional Materials journal, Vol. 22, No. 4, February 22, 2012.

Apr 2011 - A paper titled “Transparent, Well-Aligned TiO2 Nanotube Arrays with Controllable Dimensions on Glass Substrates for Photocatalytic Applications” by Dr Gao Han, Ms Tan Lee Kheng and Dr Manipaddy Kumar was one of the top 5 most accessed articles in 2010 for ACS Applied Materials & Science. By using an atomic layer deposition (ALD) technique, the researchers were able to make nanotubes with wall thicknesses that could be precisely controlled so that they were sufficiently thin to be transparent while sufficiently thick for excellent photocatalytic performances. The transparent TiO2 nanotube arrays on glass substrates with excellent photocatalytic properties might have potential applications in self-cleaning coating, transparent electronics, and solar cells.
Feb 2011 - Nanodisk heterostructures consisting of monoclinic Cu1.94S and wurtzite CdS have been colloidally synthesised for the first time. This was described in a paper by IMRE’s Dr Han Ming Yong, Dr Michelle D. Regulacio, Dr Lim Suo Hon, Dr Michel Bosman and Dr Zhang Jie on “One-Pot Synthesis of Cu1.94S−CdS and Cu1.94S−ZnxCd1−xS Nanodisk Heterostructures” ; J. Am. Chem. Soc, 2011, 133 (7), pp 2052–2055; DOI:10.1021/ja1090589 . Initially, hexagonal-shaped nanodisks of Cu1.94S were produced upon thermolysis of a copper complex in a solvent mixture of HDA and TOA at 250 °C. Rapid addition of Cd precursor to the reaction mixture resulted in the partial conversion of Cu1.94S into CdS, yielding Cu1.94S−CdS nanoheterostructures. The original morphology of the Cu1.94S nanodisks was conserved during the transformation. When Zn precursor was added together with the Cd precursor, Cu1.94S−ZnxCd1−xS nanodisks were generated. The unique feature that sets this method from currently practiced techniques is that it creates p-n junctions in a single nanocrystal.

Dec 2010 - A paper by IMRE’s Dr Han Ming-Yong and Dr Liu Shuhua was cited as one of the top downloaded articles for 2010 by Chemistry – An Asian Journal. The paper was on Silica-Coated Metal Nanoparticles. The advanced high-quality synthesis of dense and porous silica-coated nanostructures is enjoying ever-increasing research interests for their important properties and diverse applications, especially for catalytic, controlled release, colorimetric diagnostics, photothermal therapy, surface enhanced Raman scattering (SERS) detection, and so forth. Dr. Han Ming-Yong and Dr. Liu Shuhua are looking to develop robust biocompatible silica-coated surface-enhanced raman spectroscopy (SERS) nanotags for diverse in-vitro-& in-vivo bio-applications. Additionally, they are going beyond silica nanoshell materials and doing technologically important oxide-coating research recently in order to develop green and robust nanocatalysts for sustainable environment and better life.
Oct 2010 - A new revolutionary technique for making hydrogels that is biocompatible, biodegradable and can be easily moulded into various shapes and sizes was published in a paper by IMRE’sDr Liu Ye, Dr Wu De Cheng and Dr Loh Xian Jun. Entitled, “‘Living’ Controlled in Situ Gelling Systems: Thiol−Disulfide Exchange Method toward Tailor-Made Biodegradable Hydrogels”; J. Am. Chem. Soc., 2010, 132 (43), pp 15140–15143; DOI:10.1021 /ja106639c, the paper talked about a ‘living’ controlled hydrogel formation method to create loose and compact in situ biodegradable hydrogels. The method executed under mild reaction conditions can conveniently tailor the hydrogel properties. The unique advantage of this novel approach lies in the “living” property, i.e., the cross-linking can be initiated, terminated and re-initiated in cycle. Therefore the cross-linking degree of the same hydrogel can be tuned to meet requirements easily and in a controllable way. In contrast, it is difficult to control the cross-linking degree of other approaches once the cross-linking reactions are started. The innovation can be exploited to prepare ‘block’ hydrogels, micro-/nano- hydrogels, hydrogel fibres and capsules incorporating active agents for drug delivery, tissue engineering and other biomedical applications
