| 摘要 |
The present invention concerns methods and compositions relating to matrix arrays. In certain embodiments, the arrays are translucent. In other embodiments, the arrays are reconfigurable. In preferred embodiments, the arrays are translucent and reconfigurable. Reconfigurable arrays may be produced using small linker molecules, such as aptamers or affibodies, attached to the array substrate. Preferably, the small linker molecules bind to an IgG specific portion of antibodies. Such arrays may be used to detect any target that binds selectively or specifically to an IgG, allowing great flexibility of use. Translucent matrix arrays may utilize a translucent, colloidal form of nitrocellulose to coat the array substrate.
