Graphene and friends: A new method to make 2D materials
A new process can create large numbers of single-layer nanosheets quickly and efficiently, applicable to any suitable bulk material.
Highly Active Enzymes on Graphene Oxide Surface
Chemically reduced graphene oxide is a good substrate for high enzyme loads, with activities comparable with those found in solution.
What Is My (Nano)Material Good For?
Whatever happened to curiosity-driven research aimed at the creation of fundamental knowledge without the need for immediate application?
Two Layers are Better than One for Nitric Oxide Detection
Nitric oxide detectors made of two to four layers of MoS2 incorporated into a field-effect transistor outperform a single-layered device.
Waterproof your Walkman – Superhydrophobic ZnO Device Components
The development of nanostructured ZnO components for devices could lead to inherently waterproof electronic devices.
Nanoprinting on Patterned Surfaces
Nanosized features can easily be printed accurately onto an already patterned surface, using a new technique called nanoimprinting by melt processing.
Small, Quick, and Multitasking: Optimized Nanostructure Synthesis and Morphology
Making exactly the noble metal nanostructure you want is now much simpler, thanks to a microfluidic array developed by US and Chinese researchers.
Responsive Labels for Cells
How do you stick a label on something as small as a cell? Cell-labeling techniques are explained, and the use of polymer-coated nanoparticles as environment-sensitive cell labels is demonstrated by scientists in Germany and Australia.
How Green Does Your Nanomaterials Garden Grow?
