Single-molecule detection with nanodumbbells

Surface-enhanced Raman scattering (SERS) offers enormous potential for chemical sensing, even though the large nonlinearity of the effect makes reproducible sensing difficult. SERS relies upon a fundamental phenomenon in physics called the Raman effect - the change in the frequency of monochromatic light, such as a laser, when it passes through a substance. Properly harnessed, Raman scattering can identify specific molecules by detecting their characteristic spectral fingerprints. A novel DNA-based assembly technique developed by scientists in South Korea now offers a means of precise engineering of gap distances in nanoparticle dumbbells for a robust surface-enhanced Raman sensing of DNA and RNA molecules.

Singapore-French nanotechnology laboratory opens in Singapore

Just two months after the Nanyang Technological University (NTU) signed the Memorandum of Understanding in Paris with the National Center for Scientific Research (CNRS) and the Thales Group of Companies to set up a joint research laboratory, the three parties are meeting again in Singapore to inaugurate the CNRS-International-NTU-Thales Research Alliance (CINTRA) Laboratory at NTU.

A risk manager’s approach to nanotechnology

A scarcity of empirical data - especially regarding losses - hampers nanotechnology-related risk dialogue. Nanotechnology is a growing niche, so there is little litigation or loss history to analyze. Thus, much of the discussion of nanotechnology and its management flows from hypothetical examples. Less murky is the fact that nanotechnology is not a passing fad. It has innovative applications for a range of technologies and sectors, including drug delivery, medical imaging, integrated sensors, and semiconductors. The biggest areas of nanotechnology risk management concerns lies in workers' compensation and product liability. This article looks at industry responses and risk management strategies.
