There is perhaps no greater humanitarian potential in graphene than its ability to filter water. What, for instance, could be more compelling than the prospect of a graphene drinking straw that removes the impurities in water and produces crystal clear refreshment in the remotest of locations? Surely such a possibility shows us, in as stark and as matter a fact a way as possible, why every pound of the British government’s recent pledge of support for the industry is worthy of applause. Yet, as you may have come to expect, the story of graphene’s world changing potential does not end there.
Less costly ways of seqequencing DNA could open new possibilities for disease prevention.
Engineers at the University of Texas at Dallas have used advanced techniques to make the material graphene small enough to read DNA by shrinking the size of a graphene pore to less than one nanometer — opening the possibility of using graphene as a low-cost tool to sequence DNA.
The latest piece of research to emerge from the University of Houston and Case Western Reserve University has shown that graphene may be used as a antimicrobial coating for surgical equipment and other surfaces. The news reinforces findings announced earlier this year by Prof Bingan Lu and strengthens the case for the use of graphene composites in applications where bacterial infection is thought problematic.
Researchers at The University of Manchester have demonstrated that graphene can be used as a building block to create new 3D crystal structures which are not confined by what nature can produce.
Sandwiching individual graphene sheets between insulating layers in order to produce electrical devices with unique new properties, the method could open up a new dimension of physics research.
Two recent findings in the world of graphene illustrate how graphene continues to be a subject worth following. Subjects in their infancy give rise to all kinds of interesting and unexpected discoveries, and in the case of graphene these discoveries occur with astonishing frequency. However, the two latest findings, one from the very birthplace of graphene science, Manchester University, and one from Tianjin University in China, show in different ways how the miracle material just gets better and better.
