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.

A paper by Dr Liu Hong Fei, Dr Liu Wei, Prof Chua Soo Jin and Dr Chi Dongzhi on “Cracking thin-solid GaN films into nanobelts” has been highlighted as a piece of Lab & Fab news by the Compound Semiconductor Magazine. A new benchmark for performance has been set by IMRE researchers who have fabricated InGaN/GaN hetero-structured nanobelts. The structure and doping of these belts can vary, allowing greater control for potential applications in piezotronic and optoelectronic devices.

Dr Loh Xian Jun, an IMRE scientist currently doing his post-doctoral work with the University of Cambridge was recently elected as the first Singaporean Research Fellow at Fitzwilliam College. A very notable alumni of Fitzwilliam College is Singapore's first Prime Minister, Mr Lee Kuan Yew. Dr Loh, whose research interests include self-assembly of polymers, hydrogels and biomaterials, is sponsored under the A*STAR Graduate Scholarship and is currently listed as a Visiting Professor in the Melville Labs in Chemistry at Cambridge. Xian Jun was awarded the Singapore National Science Talent Search (NSTS) Merit Award in 1999 and the NSTS / NSS (BS) Scholarship in 2002. He completed his Bachelor degree in Applied Science at NUS with First Class Honors in 2006. After a research attachment at IMRE for the period Xian Jun went on to pursue his PhD studies in Singapore on the A*STAR Graduate Scholarship (NUS) in 2007. Following the completion of his PhD studies in Dec 2009 he was deployed to IMRE under the guidance of Dr Li Jun before being awarded the A*STAR Graduate Scholarship (Postdoctoral Fellowship) in Oct 2010 to do post-doctoral training at Cambridge.

IMRE’s Dr Emma Luong Van will lead a joint project with Dr Bina Rai from the Institute of Medical Biology (IMB) under a research grant under the A*STAR Scientific Conference Young Research Collaborative Grant on enhanced bone implants. The R&D project looks at new nanocomposite material for bone implants that not only make the implants stronger but has embedded biomolecules that enhances the healing of damaged bones. The researcher’s goal is to create a synthetic material that has both the bone healing properties as well as the load-bearing mechanical properties of natural bone. The researchers believe that the material developed will have strong clinical potential.

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.

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.
