This sensor, which uses aptamers (a type of artificial antibody), is more sensitive that antigen-based sensors and detects the virus more quickly and cheaply than PCR tests. These new devices can be incorporated into portable diagnostic systems and are easy to use.
Measuring the volume, motion and contents of microscopic droplets is important for studying how airborne viruses spread (including those that cause COVID-19), how clouds reflect sunlight to cool the Earth, how ink jet printers create finely detailed patterns, and even how a soda bottle fragments into nanoscale plastic particles that pollute the oceans.
Scientists have used state-of-the-art 3D printing and microscopy to provide a new glimpse of what happens when taking magnets to three-dimensions on the nanoscale.
Researchers have created a semiconductor material that acts like a second skin layer and is up to 200% more stretchable than its original dimension without significantly losing its electric current.
Researchers have discovered that the many-body effects, particularly the electronic quantum correlation, can be tuned in metallic vdW monolayers through moire engineering.
