University of Tehran Researchers Grow Porous, Hollow Nanostructures

Tehran, Iran | Posted on November 25th, 2013

The method used by the researchers was used in the past for the synthesis of silicate nanowires, but the growth of the nanostructures was not possible before.

The main objective of the research is the creation of silicone nanotubes without template and the use of growth through vapor-liquid-solid (VLS) or solid-liquid-solid (SLS) methods. These methods had been used in the past for the creation of silicone nanowires, but the growth of porous and hollow nanostructures was not possible in them. The growth was materialized by using the combination of gold and nickel as the growth catalyst.

In this research, silicone nanotubes have been formed through a highly repeatable and almost simple method. Carbon nanotubes have been created for many years but it was not possible to synthesize silicone nanotubes. On the other hand, the nanostructures have promising future due to unique properties of silicone. One of the applications of these materials can be the simple production of field effect transistors. Moreover, the nanotubes are able to unzip by electronic current that is used in electron microscopy. Therefore, it is simple to produce silicone nanobands.

Results of the research have direct applications in electronics and bioelectronics. In case tubes with very small diameters and appropriate length can be produced, it is possible to produce field effect transistors with floating gate that can be controlled from inside. In this case, transistor current changes when a very small and charged creature such as DNA passes by, and it can be measured. Taking into consideration the very small size of this piece, DNA can be arranged in parallel position to complete sequencing data.

Results of the research have been published in ISI-indexed journal in Nano Letters, vol. 13, issue 3, 2013, pp. 889-897.
