Droplets can be designed in a specific shape and pattern, which could be used to control cell growth and movement as well as to make new nanocomponents.
Trojan Horse Causes Nanoparticle Allergy
Workers with existing allergic conditions have worse reactions when exposed to nanoparticles, caused by a Trojan horse known as an exosome.
Graphene for Energy
Graphene has the potential to solve many issues in vital energy research.
Testing for Enzyme Activity using Gold Nanoparticles
A new protocol combines gold nanoparticles with an enzyme substrate to give a simple test for the activity of an enzyme, the results of which can be seen with the naked eye.
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.
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.
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.
A Material for All Weathers (with Zero Thermal Expansion)
Specialized materials that do not change their volume with alteration of temperature may now be easier to produce, thanks to work into the mechanism of such behavior in antiperovskite manganese nitrides.
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.
