Today, much has changed when it comes to metals and materials in general, but one thing remains the same: It's advancement in this industry that drives innovations and breakthroughs everywhere else.
Scientists have developed a new method for optical manipulation of matter at the nanoscale. Using ‘plasmonic hotspots’ – regions with electric current that heat up very locally – gold nanostructures can be melted and made to produce the smallest nanojets ever observed. The tiny gold nanodroplets formed in the nanojets, are perfectly spherical, which makes them interesting for applications in medicine.
