Plants open their pores and scientists strike gold

14.06. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Plants containing the element gold are already widely known. The flowering perennial plant alfafa, for example, has been cultivated by scientists to contain pure gold in its plant tissue. Now researchers from the Sun Yat-sen University in China have identified and investigated the characteristics of gold nanoparticles in two plant species growing in their natural environments. The study, led by Xiaoen Luo, is published in Springer's journal Environmental Chemistry Letters and has implications for the way gold nanoparticles are produced and absorbed from the environment.

Graphene carpets: So neurons communicate better

13.06. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

A study led by SISSA and published in Nature Nanotechnology reports for the first time the phenomenon of ion trapping by graphene carpets and its effect on the communication between neurons. The researchers have observed an increase in the activity of nerve cells grown on a single layer of graphene. Combining theoretical and experimental approaches, they have shown that the phenomenon is due to the ability of the material to 'trap' several ions present in the surrounding environment on its surface, modulating its composition. Graphene is the thinnest bi-dimensional material available today, characterised by incredible properties of conductivity, flexibility and transparency. Although there are great expectations for its applications in the biomedical field, only very few works have analysed its interactions with neuronal tissue.
