Abstract

We describe a novel fabrication method for producing polymer, glass, and metal micro- and nano-particles whose diameters range from 200 microns to under 50 nanometers. This method relies on the Rayleigh capillary instability in a multi-material fiber. The fiber core is made of the target material and has size close to the desired particle diameter embedded in a sacrificial polymer matrix. The fiber temperature is elevated to reduce the core viscosity and the Rayleigh instability results in the breakup of the core into a periodic string of spherical particles.
