Nanotechnology

Although a concrete definition of nanotechnology remains elusive, the interest in nanotechnology and the possibilities it offers continues to grow. The study of nano materials is important as unusual physical, chemical, and biological properties can emerge in material at the nanoscale, and these properties may differ in important ways from the properties of bulk materials and single atoms or molecules. To study these properties and build products from the bottom up, researchers need instruments to help them succeed. Shimadzu recognizes this need and offers a range of systems to ensure you obtain the precise data to engineer your breakthrough.

Examples of Nanotechnology Applications and Required Instrumentation

Particle Size Measurement: The IG-1000 utilizes new Induced Grating (IG) technology for measuring nano particles in the 0.5-200 nm range. The new technology has three main advantages over the current technology: the dynamic light scattering (DLS) technique. First, the sensitivity is the same when measuring a 1 nm particle or 100 nm particles. With DLS, a 1 nm particle is 1 million times less sensitive then a 100 nm particle. Second and third, interferences from clustering or contamination are significantly reduced or eliminated. These interferences are a major problem with the DLS technique. Additionally, the SALD-7101 can measure particles in the 10nm – 300 um range.

Absorption Properties: UV-Vis-NIR can measure the absorption properties of gold and silver coated nanoparticles. If samples are temperature dependent then the S1700 thermal melt system may be added as an option.

Surface Analysis: Characterization of coated surfaces in the mid-IR (MIR) and near-IR (NIR) regions can be accomplished with the IRPrestige, AIM Microscope, and other special accessories. X-Ray Photoelectron Spectroscopy (XPS) by Shimadzu's sister company Kratos can be used to analyze the chemical state of the surface of substances.

Quantum Dots: Analysis of the fluorescence of quantum dots can be achieved with the RF-5301 while particles size can be measured with the IG-1000.

Carbon Nanotubes: Biological aspects of carbon nanotubes can be measured with the UV-3600 and IRPrestige spectrophotometers. In addition, particles size can be measured with the IG-1000 and carbon nanotube purity can be measured by TGA-50 thermal analysis instrumentation.

Evolved Gas Components: The GCMS-QP-2010 Series of Gas Chromatograph Mass Spectrometrs can be used for measuring evolved gases.
