Cryo-electron Microscopy Enables Breakthrough Imaging of Individual Atoms in Proteins

A game-changing technique for imaging molecules known as cryo-electron microscopy has produced its sharpest pictures that for first-time can see individual atoms in a protein. By achieving atomic resolution using cryogenic-electron microscopy (cryo-EM), researchers will be able to understand, in unprecedented detail, the workings of proteins that cannot easily be examined by other imaging techniques, …

Lasers Hold a Few Hundred Atoms to Create the Smallest Optical Mirror

Physicists at the Max Planck Institute of Quantum Optics (MPQ) have made an optical mirror using only a few hundred identical atoms. They used a new metamaterial made of a single structured layer. few hundred identical atoms. Interfering laser beams hold two layers of atoms in arrays. This has come from an emerging new field …

Nanogaps Between Metals Create Light Ten Thousand Times Brighter Than Expected

Nanogaps between plasmonic electrodes produced 10,000 times more light than expected. Hot electrons were created by electrons driven to tunnel between gold electrodes, their recombination with holes emitted bright light, and the greater the input voltage, the brighter the light. This could be useful for applications in optoelectronics, quantum optics and photocatalysis. The effect depends …

Visual Scanning of the Chemical Structure of Single Molecules at Angstrom Resolution

Nanocavity plasmonic fields can create Raman images of molecular vibration for a visual system that can map the chemical structure of single-molecule. This visual system has 0.1 nanometer (an angstrom) resolution. They merge the images at several different vibration modes to generate the image with the chemical structure. Arxiv has the full article. Scanning Raman …

Two-photon Lithography Boosts Nanoprinting Speed by up to 10,000 Times

Femtosecond Projection Two-photon Lithography (FP-TPL) printing technology increases the printing speed by 1,000 – 10,000 times, and reduces the cost by 98%. It controls the laser spectrum via temporal focusing, the laser 3D printing process is performed in a parallel layer-by-layer fashion instead of point-by-point writing. This is a technological breakthrough that leads nanoscale 3D …

Electric Signal Detection from Single Molecules for Molecular Electronics Revolution

The barrier to molecular electronics was the previous inability to detect the tiny electric signals from single molecules. Roswell Biotechnologies overcame that problem and integrated the solution with CMOS. This enables an interface between molecules for sensors and DNA and other biological detections with CMOS. Nanopores have existed for a long time and being able …

Perfect Waveforms for Optical Tweezers to Move Atoms, Molecules and Living Cells

Researchers have calculated perfect optical tweezers for manipulating atoms, molecules or even living cells. A special calculation method was developed to determine the perfect waveform to manipulate small particles in the presence of a disordered environment. This makes it possible to hold, move or rotate individual particles inside a sample – even if they cannot …
