Claim Text:
1. A method for producing particles comprising: providing a drawn fiber having a longitudinal-axis fiber length and including at least one fiber core having a longitudinal core axis parallel to the longitudinal fiber axis and internally disposed to at least one outer fiber cladding layer along the fiber length; heating the fiber at a heating temperature, T, for a heating time, t, that is sufficient to cause at least one fiber core break up into droplets that are sequentially disposed along the fiber core axis; and cooling the heated fiber to solidify the droplets into spherical particles that are disposed along the fiber core axis over the fiber length, interior to the fiber cladding layer, as a longitudinal sequence of spherical particles that is parallel to the longitudinal fiber axis.
