Researchers produce nanodiamonds capable of delivering medicinal and cosmetic remedies through the skin

Using advanced optics technology, the exact location and concentration of nanodiamonds can be monitored non-invasively, eliminating the need for a biopsy

01-Sep-2022 - The skin is one of the largest and most accessible organs in the human body, but penetrating its deep layers for medicinal and cosmetic treatments still eludes science. Although there are some remedies -- such as nicotine patches to stop smoking -- administered through the skin, this method of ...

A "nano-robot" built entirely from DNA to explore cell processes

02-Aug-2022 - Constructing a tiny robot from DNA and using it to study cell processes invisible to the naked eye... You would be forgiven for thinking it is science fiction, but it is in fact the subject of serious research by scientists from Inserm, CNRS and Université de Montpellier at the Structural Biology ...

First electric nanomotor made from DNA material

Synthetic rotary motors at the nanoscale perform mechanical work

27-Jul-2022 - A research team led by the Technical University of Munich (TUM) has succeeded for the first time in producing a molecular electric motor using the DNA origami method. The tiny machine made of genetic material self-assembles and converts electrical energy into kinetic energy. The new nanomotors ...

Nanotechnology enables visualization of RNA structures at near-atomic resolution

Combination of nucleic acid nanotechnology and cryo-EM gives unprecedented insights into the structures of large and small RNAs

04-May-2022 - We live in a world made and run by RNA, the equally important sibling of the genetic molecule DNA. In fact, evolutionary biologists hypothesize that RNA existed and self-replicated even before the appearance of DNA and the proteins encoded by it. Fast forward to modern day humans: science has ...

CSIC spin-off company develops technology to prevent drug counterfeiting

The company Molecular Gate, created by ICMAB researchers, offers a smart labeling material based on nanotechnology only visible by polarized light.

21-Mar-2022 - A CSIC spin-off company has developed a nanotechnology-based method to improve product labeling to prevent counterfeiting. The technology consists of controlling the nanostructure of the elements printed on the surface of the product, taking into account their molecular orientation and the ...

Maize and milk proteins can replace fossil fuels and metals in the production of nanostructured surfaces

Sustainably produced nanotechnology

28-Jan-2022 - New research results from Linnaeus University opens for a future with more sustainably produced nanotechnology, where limited natural resources can be replaced with, among other things, maize and milk proteins. Nanotechnology can be found almost everywhere in our daily lives, although it is ...

Chemists use DNA to build the world’s tiniest antenna

"The results are so exciting that we are currently working on setting up a start-up company"

12-Jan-2022 - Researchers at Université de Montréal have created a nanoantenna to monitor the motions of proteins. Reported this week in Nature Methods, the device is a new method to monitor the structural change of proteins over time – and may go a long way to helping scientists better understand natural and ...

Researchers turned transparent calcite into artificial gold

Breakthrough in metamaterials: New material can serve as a platform for innovative cancer treatments

15-Jun-2021 - For the first time in the world, researchers at Tel Aviv University developed an innovative nanotechnology that transforms a transparent calcite nanoparticle into a sparkling gold-like particle. In other words, they turned the transparent particle into a particle that is visible despite its very ...
