| ABSTRACT: |
SSLS is in the routine operation with five beamlines since November 2003. Recent applications are related to micro/nano-fabrication, material science and the development of fourth generation synchrotron radiation sources. There is also a strong interest in Singapore in development and applications of synchrotron radiation in biology and medicine. The speaker has been involved in several new projects at SSLS, such as:
・High resolution and high sensitivity X-ray microscopy/microprobe. The old saying that ＜seeing is believingｃ has particular resonance for studying biological systems. Since 1677, when Anton van Leeuwenhoek used a simple light microscope to discover single cell organisms, scientists have relied on structural information obtained from microscopes with improving capabilities to advance understandings of how cells and biological systems work. In recent years, increasingly powerful imaging methods have provided more detailed views of biological systems. Recent results achieved at an existing phase contrast imaging and tomography (PCIT) beamline at the Singapore Synchrotron Light Source (SSLS) have shown that imaging with resolution down to 0.7 シm of 2-dimensional (2D) and 3-dimensional (3D) imaging could be extremely useful tool for different materials characterization, including biomaterials. The author will spend some time discussing future program for high resolution (down to 50 nm) at SSLS.
・Single cell irradiation system. While in Singapore he has been also involved in the development and applications of high resolution live cell high irradiation facilities with X-rays & ions which also will be discussed.
・Development of new detectors. Detectors used for detecting X-rays, ions and electrons play an important role in science and industry. The old detectors are being replaced recently by new generation detectors. The use of new nanomaterials as a material of choice for development of new detectors is a new concept. |
