Our world is full of patterns, from the twist of a DNA molecule to the spiral of the Milky Way. New research has revealed that tiny, synthetic gold nanoparticles exhibit some of nature's most intricate patterns.
New understanding of the nature of electromagnetism could lead to antennas small enough to fit on computer chips - the 'last frontier' of semiconductor design - and could help identify the points where theories of classical electromagnetism and quantum mechanics overlap.
Researchers managed to create artificial viruses, protein complexes with the ability of self-assembling and forming nanoparticles which are capable of surrounding DNA fragments, penetrating the cells and reaching the nucleus in a very efficient manner, where they then release the therapeutic DNA fragments. The achievement represents an alternative with no biological risk to the use of viruses in gene therapy.
Researchers developed an aqueous system that uses a single starting point to induce self-assembly formation, whose stability is pre-programmed with a lifetime before disassembly occurs without any additional external signal - hence presenting an artificial self-regulation mechanism in closed conditions.
Researchers succeeded for the first time in identifying the atomic structure and bonding mechanism in coherent interfaces between diamond, the hardest known material, and cubic boron nitride, the second hardest.
Using standard semiconductor manufacturing equipment, researchers have demonstrated a nano-mechanical plasmon phase modulator that can control and manipulate the flow of plasmons at the nanoscale without any degradation in optical performance.
