Graphene-Based Paper Can Be Programmed to Walk

Engineers from Donghua University in Shanghai have developed a graphene-based paper that can walk and fold itself. Inspired by origami, the nanostructure can be excited by light or heat to change shapes, walk or turn around a corner. The study, published in Science Advances, could find applications in robotics, sensing and the creation of artificial muscles. Origami has influenced […]

Nanopore Technology Could Desalinate Seawater

An ultra-thin sheet of molybdenum disulfide (MoS2) could let water molecules pass through tiny nanopores at a high rate while keeping ions and any contaminants. The authors of the study, a research team from the University of Illinois, ran desalination simulations for several materials in a supercomputer and concluded that MoS2 was the most efficient, 70% better than graphene. The finding […]

A New Nanopore Sequencer with Graphene Technology

Researchers from University of Illinois at Urbana-Champaign (UIUC) have developed a new nanopore sequencing method based on graphene nanoribbons that detects double and single stranded DNA in different configurations. The unparalleled thinness of graphene allows high resolution scanning, and electronic sensing of biomolecules is possible thanks to graphene´s semiconductor properties. There is a growing interest among scientists in finding a cheap, […]

Insulator Defects Observable by Scanning Tunneling Microscopy

Researchers from the Lawrence Berkeley National Laboratory and the University of California at Berkeley have characterized individual defects in an insulator using scanning tunneling microscopy (STM). The researchers covered the bulk insulator with a graphene layer that transmitted the current -necessary for STM observation- to the insulator surface. The findings have been published in the journal Nature […]

IR Spectroscopy Gets Better with Graphene Sensor

In one of the firsts, researchers from Ecole Polytechnique Federale De Lausanne (EPFL) and The Institute of Photonic Sciences (ICFO) have created a sensor made of graphene. The new sensor is capable of detecting biomolecules like proteins and drugs. The research team has exploited the optical and electrical properties of unilayer graphene nanomaterial to create […]

Writing Artificial Cell Membranes on Graphene

Researchers at Karlsruhe Institute of Technology are reporting on a breakthrough in creating artificial cell membranes on graphene. Using Lipid Dip-Pen Nanolithography, the researchers demonstrated that cell membranes can be written on graphene the same way ink is used to write on paper. The cell membrane is a complex phospholipid bi-layer that covers every cell […]

New AFM Based Imaging Technique Developed to Visualize Chemicals in Atomic Resolution

In one of the firsts, researchers from University of California, Berkeley have caught a single atom resolution image of a molecule in the act of rearranging its bonds. The carbon molecule from graphene, in the process of rearranging itself, has become the first molecule to be visually captured at that resolution. The atomic bonds, each […]
