Nanocages in the lab and in the computer: How DNA-based dendrimers transport nanoparticles

ScienceDaily.com: Nanotechnology News - Thu, 10/18/2018 - 22:12
How to create nanocages, i.e., robust and stable objects with regular voids and tunable properties? Short segments of DNA molecules are perfect candidates for the controllable design of novel complex structures. Physicists investigated methodologies to synthesize DNA-based dendrimers in the lab and to predict their behavior using detailed computer simulations.

Insight into how nanoparticles interact with biological systems

ScienceDaily.com: Nanotechnology News - Thu, 10/18/2018 - 22:10
Personal electronic devices are a growing source of the world's electronic waste. Many of these products use nanomaterials, but little is known about how nanoparticles interact with the environment. Now chemists have discovered that when certain coated nanoparticles interact with living organisms it results in new properties that cause the nanoparticles to become sticky. Nanoparticles with 5-nanometer diameters form long kelp-like structures that are microns in size. The impact on cells is not known.

Nanodiamonds as photocatalysts

ScienceDaily.com: Nanotechnology News - Thu, 10/18/2018 - 20:52
Diamond nanomaterials are considered hot candidates for low-cost photocatalysts. They can be activated by light and can then accelerate certain reactions between water and CO2 and produce carbon-neutral 'solar fuels'. The EU project DIACAT has now doped such diamond materials with boron and shown at BESSY II how this could significantly improve the photocatalytic properties.

Extremely small magnetic nanostructures with invisibility cloak imaged

ScienceDaily.com: Nanotechnology News - Thu, 10/18/2018 - 18:53
In novel concepts of magnetic data storage, it is intended to send small magnetic bits back and forth in a chip structure, store them densely packed and read them out later. The magnetic stray field generates problems when trying to generate particularly tiny bits. Now, researchers were able to put an 'invisibility cloak' over the magnetic structures. In this fashion, the magnetic stray field can be reduced in a fashion allowing for small yet mobile bits.
