Each porous particle comprises a polymer that provides a continuous solid phase including an external particle surface, and first and second discrete pores that are isolated from each other and dispersed within the continuous solid phase. The porous particle further comprises a first marker material present in the first discrete pores, and a second marker material that is detectably different from the first marker material and is present within the second discrete pores. The marker materials can provide a means for identifying documents, clothing, or other articles as genuine, and providing a detectable security system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Articles with porous particles for security purposes","description":"An article comprises one or more porous particles.
