A laser pointer small enough to get inside a cancer cell and stop its 'engine'? The stuff of science fiction? Scientists working at the nanoscale are chipping away at how to build miniature laser devices capable of intracellular bio-imaging and sensing.
Nanoengineers at the University of California San Diego have developed new and improved probes, known as positive controls, that could make it easier to validate rapid, point-of-care diagnostic tests for COVID-19 across the globe. The advance could help expand testing to low-resource, underserved areas.
The first experimental observation of three-dimensional magnetic 'vortex rings' provides fundamental insight into intricate nanoscale structures inside bulk magnets, and offers fresh perspectives for magnetic devices.
To develop effective therapeutics against pathogens, scientists need to first uncover how they attack host cells. An efficient way to conduct these investigations on an extensive scale is through high-speed screening tests called assays.
Australian researchers have located the 'sweet spot' for positioning qubits in silicon to scale up atom-based quantum processors.
Scientists from ICFO and University Rovira i Virgili report on a novel Raman holographic technique capable of tracking individual particles in 3D volumes from one single image.
A study in Science Advances by ICFO researchers, in collaboration with Massachusetts General Hospital, reports on a novel fluorescence holographic technique for the fast tracking of the 3D motion in cells.
Scientists of Far Eastern Federal University (FEFU) with international collaborators propose direct magnetic writing of skyrmions, i.e. magnetic quasiparticles, and skyrmion lattices, within which it is possible to encode, transmit, process information, and produce topological patterns with a resolution of less than 100 nanometers. This brings closer miniaturized post-silicon electronics, new topological cryptography techniques, and green data centers, reducing the load on the Earth's ecosystem significantly. A related article appears in ACS Nano.
The University of Technology Sydney (UTS) led collaboration developed a nanocrystal growth method that controls the growth direction, producing programmable atomic thin layers, arbitrary barcoded nanorods, with morphology uniformity. The result is millions of different kinds of nanobarcodes that can form a 'library' for future nanoscale sensing applications.
Kyoto University researchers report on a new model for spider silk assembly. The key to spider silk 'spinning' is a combination of acidification and a process known as liquid-liquid phase separation, or LLPS.
