Hollow nanosized needles, or nanostraws, are a promising tool for opening up tiny, temporary holes in cell membranes to deliver molecules or sample a cell’s contents. Nanostraws could also deliver ...

Scientists have combined 3-D-printing with electroplating to easily produce high-quality metal electrodes that can be used as a molecular beam-splitter. Many measurement techniques, such as ...

Many measurement techniques, such as spectroscopy, benefit from the ability to split a single beam of light into two in order to measure changes in one of them. The crucial device that separates the ...
