Few methods are able to analyze single molecules. Analysis problems occur due to the instability of thin molecular layers and especially single molecules with respect to their thermal-, chemical- and photo-degradation or to external mechanical fields caused scanning probe techniques. A disadvantage of Raman scattering methods is the large amount of heat produced by the focused plasmons localized at the active site, which can cause damage of the molecules. Graphene exhibits plasmon resonance in the ultraviolet and blue spectral region and thus can enhance Raman signals. Graphene is a monoatomically thick and flexible layer, which provides thermal and electrical conductivity as well as high optical transparency and impermeability to gases and liquids. Thus graphene can act as protective layer against local heating.<br><br> <!--break--><strong>Technology</strong><br> This novel method allows the analysis of substances in very small quantities, even single molecules, with common techniques. The substances to be analyzed are covered with a graphene layer. <br> <br>

Different eras of civilization are defined by the discovery of new materials, as new materials drive new capabilities. And yet, identifying the best material...
Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...
What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...
A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
