New exotic Azo-oparticles with directional superficial photofluidization

A group of new colloidal azopolymers were synthesized. This particle group possesses a core of PMMA and a fragmented shell of azopolymer, resembling a buckyball. Under laser illumination, this fragmented shell gives rise to a set of unique shape particles such as; porcupine and sea pineapple particles, opening new doors for study of the phenomena of SRG formation and the basic understanding of the light-matter interaction. The uses and knowledge gained from particles with defined shapes seem limitless, and the availability of a simple method to make such particles will catalyze many new discoveries and technologies
