A microscope that can move atoms and draw super high resolution surface images of living cells

• A*STAR’s IMRE houses some of the world’s leading experts in SPM which was built for the physical sciences but is now widely adopted by biologists
• SPM studies can help engineer novel techniques to reduce friction between surfaces at the molecular level and further miniaturise electronics.

1. The scanning probe microscope (SPM) can manipulate single atoms, move them in a controlled manner and help create novel nano-sized structures with very high precision. It can also map the terrain of living cells and allows biologists to obtain high-resolution images of a cell’s surface. The uniqueness and versatility of the tool is underscored in a new book by local researchers from A*STAR’s Institute of Materials Research and Engineering (IMRE). The book covers the practical uses of SPM and Singapore’s significant contribution in this area.

2. The SPM creates extremely accurate high-resolution images of a specimen’s surface by moving an extremely fine metal probe - which is a thousand times less than a hair’s breadth - across the surface, one parallel line at a time. SPM can be used to image materials with atomic-scale resolution and can be used to study living cells in their original liquid-filled environments. SPM has also allowed A*STAR IMRE scientists to create the world’s first controllable molecular gear and secure a place in a €10million European Union (EU) project to build a molecule-sized processor chip.

3. IMRE has more than 10 SPM systems which are used across multiple disciplines, such as physics, chemistry, and biology. Data gained from SPM can be used to benefit the semiconductor industry, advance molecular electronics, control friction between two surfaces at the molecular level and help in further scaling down the size of electronics.

4. “I believe it is a good showcase of Singapore’s concerted effort in translating science into technology”, said Dr Johnson Goh, a Senior Research Engineer with IMRE and one of the editors of the book. “This book covers the latest SPM research in Singapore, with many of the works looking beyond fundamental science to applications in nanoelectronics, biology and scalable nanolithography.” IMRE also conducts annual symposiums on SPM, which involve both academic and industry partners to further promote the industry-relevant advantages of the tool.

5. The book entitled, “Scanning Probe Microscopy”, will be published by World Scientific Publishing and will be internationally available after its launch on 15 December 2010 in conjunction with the 3rd Singapore Scanning Probe Microscopy Symposium (SingSPM 2010).

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
