Fluorescent molecules and quantum dots have been received much attention for use in high-throughput screening and bioassay applications. Multistructured porous silicon (PSi) such as Rugate PSi has been recently investigated for use of its possible chemical and biological applications. Photonic structure of DBR PSi results in a mirror with high reflectivity at 533 nm. The surface modified DBR PSi is prepared by either thermal oxidation or thermal hydrosilylation. Freshly etched DBR PSi containing hydrogen-terminated surface and dodecyl-terminated DBR PSi are hydrophobic characteristics on their surface, however the surface of oxidized DBR PSi is hydrophilic. The resulting DBR PSi films have been removed from the silicon substrate by an applying of electropolishing current to obtain a free-standing DBR PSi. These freestanding films are very brittle and they can be fractured into few hundred nanometers to hundred micrometer-sized pieces in an ultrasonic bath.
