Medical Imaging: New Imaging Agent Provides Better Picture of the Gut

A multi-institutional team of researchers has developed a new nanoscale agent for imaging the gastrointestinal (GI) tract. This safe, noninvasive method for assessing the function and properties of the GI tract in real time could lead to better diagnosis and treatment of gut diseases. Results have been published online in Nature Nanotechnology.

Microscopic Study of Nanostructured AlOx

Large area ordered nanopatterning of RF sputtered AlOx layers have been carried out. The technique involves UV laser treating of the film through LB films of silica nanospheres. The hexagonal, close packed arrangement of these spheres was projected to the surface due to the laser treatment resulting in ordered structure of pits of ~200 nm diameter and 1.3 nm depths. The samples were characterized by means of AFM and XTEM. Experimental results are in good agreement with the simulations.

TEM Sample Preparation of Nanoparticles in Suspensions

Nanomaterials are of significant economic interest with a global market value of roughly 20 billion €, which is expected to rise to 2 trillion € by 2015 [1]. For commercial use, the European Union provides the following recommended definition: "‘Nanomaterial' means a natural, incidental or manufactured material containing particles, in an unbound state or as an aggregate or as an agglomerate and where, for 50% or more of the particles in the number size distribution, one or more external dimensions is in the size range 1 nm-100 nm" [2].

Highly Non-Linear Metamaterials for Laser Technology

Nonlinear optical materials are widely used in laser systems. However, high light intensity and long propagation are required to produce strong nonlinear optical effects. Researchers at The University of Texas at Austin and the Technische Universitaet Muenchen created metamaterials with a million times stronger nonlinear optical response, compared to the traditional nonlinear materials, and demonstrated frequency conversion in films 100 times thinner than human hair using light intensity comparable to that of a laser pointer.

Nano-Imaging Probes Structural Disorder in Organic Semiconductor

Using a newly developed nano-imaging method, LMU researchers show that thin-film organic semiconductors contain regions of structural disorder that could inhibit the transport of charge and limit the efficiency of organic electronic devices. The results have been published in Nature Communications.

AFM-based Virtual Nanohand Proposed for Stable Nanomanipulation

Atomic force microscopy (AFM) has become a promising tool for manipulating nano-objects to fabricate nano-structures or nano-devices. However, there are still some challenges facing the development of an AFM based robotic nanomanipulation system, such as the uncertainties associated with AFM tip and nanoparticles, the single point force and interaction between the tip and nanoparticles, and the parameter calibration of models being used. This work was published in IEEE Nanotechnology Magazine.
