The present invention generally relates to systems and methods for using particle templating, e.g., to produce composites, discrete particles, or the like. In some embodiments, the present invention generally relates to the production of particles using the interstitial spaces between templating elements in a template structure. For example, a plurality of templating elements, which can include colloidal particles, may be arranged to form a template structure. The interstices of the templating elements can provide regions in which a fluid may be introduced. The fluid may be hardened (e.g., solidified) in some cases, e.g., to form a composite comprising the templating elements and the interstitial segments. In certain embodiments, the template structure may then be broken down to release the hardened fluid, e.g., as a plurality of discrete particles.
