Abstract: Smart aerogel, an aerogel material doped with special bio-affinity compounds to providing means of unique collection, detection and identification of bioaerosols, including bacteria, viruses, toxins, and other bioaerosols. Aerogels, extremely low density and highly porous materials with a complex pore structure, are used as an intelligent detection material by incorporating specific bioaffinity pharmaceuticals directly into the matrix. The complex pore structure contains micropores, mesopores, and macropores in an open pore structure. The opening pore structure of the aerogel is used to create docking sites by linking high affinity pharmaceuticals that specifically bind only to certain bioaerosols. The high internal surface area of the aerogel and the extremely low density provides abundant receptor sites per unit mesopore for a high bioaerosol-receptor interaction, yet in a manner which will reduce possible damage and destruction to the bioaerosols captured.
