The present invention relates to functional composite particles for the oral care sector, more particularly for toothpastes and mouthwashes, which are charged with active ingredients which ensure a long-term antimicrobial or antibacterial effect in the oral cavity and hence reduce the formation of plaque and halitosis. In an implementation, a subscription data for one or more subscriptions for the health regimen information is accepted by the system. The plurality of color planes being projected onto the screen such that the first color plane comprises a different resolution than the second color plane and the third color plane. The polyimide aerogels and the polyimide aerogel derivatives consist of interconnecting mesopores with average pore size at 10 to 30 nm and a mono-dispersed pore size distribution.
