Graphene has possible uses in brain cancer treatment, neuroregeneration, functional neurosurgery, and more
The development of graphene—a highly advanced metamaterial with many unique and varied properties—may lead to exciting new applications in the diagnosis and treatment of neurological diseases, according to a report in the May issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
Tobias A. Mattei, MD, of Invision Health/Brain & Spine Center – Buffalo, New York and Azeem A. Rehman, BS, of The University of Illinois College of Medicine at Peoria present a "primer" on the development of graphene-based metamaterials that may lead to new advances in several areas of neurosurgery. Mattei and Rehman write, "As a surgical specialty that heavily relies on technological innovations, it is expected that neurosurgery will significantly benefit from several graphene-based technological developments in the next decades."
Graphene Has 'Extremely Remarkable' Properties …
An artificially engineered "metamaterial"—with properties not typically found in nature—graphene is composed of a single layer of carbon atoms in a "honeycomb lattice" pattern. The developers of graphene were awarded the Nobel Prize in Physics in 2010; massive resources are being invested in its further research and development.
Graphene has a number of "extremely remarkable" properties that make it unlike any other material. It combines the greatest mechanical strength ever measured in any material— natural or artificial—with very light weight and high elasticity. Graphene also has unique optical and photothermal properties which, among other things, allow it to release energy in the form of heat in response to light input.
In addition, graphene has very high electrical conductivity, as well as a high surface area allowing "efficient bioconjugation" with common biomolecules. A few years ago, graphene was one of the most expensive materials on Earth. However, as industrial production increases, it is dropping rapidly in price.
Graphene is being developed for use in a wide range of technologies, such as flexible liquid crystal displays and electronic devices, new types of integrated electric circuits, and lithium-ion microbatteries—to name just a few. It also has great promise for use in various types of biomedical devices, several of which are relevant to conditions treated by neurosurgeons.
…With Many Promising Applications in Neurosurgery
Mattei and Rehman discuss some of the frontline scientific research being done to explore the capabilities and potential uses of graphene. As development continues, graphene-based metamaterials could contribute to advances in several areas of neurosurgery, including:
However, much work remains before any of these advances become reality. While graphene has been shown to be biocompatible, more basic research is needed to examine the long-term biological effects of graphene implants and to answer other important clinical questions. Mattei and Rehman conclude, "Increased awareness of the ongoing frontline research on graphene may enable the neurosurgical community to properly take advantage of the technological applications such a new metamaterial may offer to experimental and clinical neurosurgery in the near future."

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
