Chemically stable films for combinatorial fluorosensor arrays

Sensor arrays are useful for many purposes. Our interests include quasidistributed intrinsic fiber optic arrays, those distributed along the length of an optical fiber. We have demonstrated an optical time-of-flight approach to distinguishing the fluorescence output of such arrays, as well as a synthesis of combinatorial libraries that takes advantage of a support of linear morphology to make numerous compounds in a simple manner without information loss in the synthesis. To unite these research areas, we needed an optical fiber cladding material that meets demanding synthetic and optical requirements. We have chosen the Meldal SPOCC polymer support as the best candidate for such a material and report here our initial results with this material.
