Nanonål
Nanonål refers to a very small needle, typically on the nanometer scale. These are not traditional sewing needles but rather specialized tools used in scientific and technological applications. Their extremely small size allows for manipulation and interaction with matter at the atomic and molecular level.
One common application of nanonålar is in scanning probe microscopy (SPM), such as atomic force microscopy (AFM).
Nanonålar can also be used for precise manipulation of individual atoms or molecules. This capability is crucial
The fabrication of nanonålar involves advanced techniques such as focused ion beam milling or electron beam
