Here are the five most viewed and interesting stories of 2014 on AZoNano, including a new carbon nanotube material which helps in the detection of explosives and nano-robots which can swim through biological fluids.

1. New Carbon Nanotube Material Helps to Detect Bombs and Deadly Gases

A handheld sensor developed by engineers from the University of Utah, uses a new carbon nanotube material in the rapid detection of toxic gases, deadly explosives and illegal substances. Vaporsens, a University of Utah spin-off company, now has plans to complete the first fabrication of a prototype by the end of 2014. Watch this space!


2. Nano-Robots Swim through Complex Biological Fluids

Nanoscale swimming bodies which can navigate through complex biological fluids is one of this years latest developments to come out of the Max Planck Institute for Intelligent Systems. A team of researchers from the Institute believe this breakthrough could facilitate accurate drug delivery to target sites.

3. Researchers Observe Growth of Buckminsterfullerenes in Real Time

An insight into the basic growth that takes place in buckyballs has been observed by a team of researchers from Humboldt-Universität zu Berlin, Universität Tübingen, Deutsches Elektronen-Synchrotron (DESY) and Technische Universität Berlin. The observation showed the self-arrangement of the carbon molecules into ultra-smooth layers, in real time.

4. Nanoreactor Model Reveals Complex Chemical Reactions of Urey-Miller Experiment

A team of chemist from Stanford University have developed a model termed as the nanoreactor, which enables the determination of mechanisms or reactions. The model will help reveal the possibility of new drug formation or improved battery efficiency.

5. Wet-Spun Carbon Nanotube Fiber Beats Copper in Carrying Electrical Current

Research from Rice university demonstrates that wet-spun carbon nanotube fibers have a greater capacity to carry electrical current than copper cables of the sme mass. The new findings offer possible applications in flexible optoelectronic devices.
