Smart Dust |
| 초록 |
Various types of distributed Bragg reflectors (DBR) porous silicon exhibiting unique reflectivity were successfully obtained by an electrochemical etching of silicon wafer using square wave currents. Optically encoded smart dust which retained optical reflectivity was obtained from the sonication of DBR porous silicon film in solution. The size of optically encoded smart dust was measured by field emission scanning electron micrograph (FESEM) and was about 500 nm to few microns depending on the duration of sonication. Optical characteristics of smart dust were investigated. Possible applications of smart dust such as biosensors, drug delivery, and chemical sensors are investigated. Optical characteristics and surface derivatization of smart dust will be discussed. |
