Array-Based Sensing of Proteins Using Conjugated Polymers Oscar R. Miranda Chang-Cheng You Ronnie Phillips Ik-Bum Kim Partha S. Ghosh Uwe H. F. Bunz Vincent M. Rotello 10.1021/ja0737927.s001 https://acs.figshare.com/articles/journal_contribution/Array_Based_Sensing_of_Proteins_Using_Conjugated_Polymers/2991490 A sensor array comprising six functionalized poly(<i>p</i>-phenyleneethynylene) polymers was constructed and used to detect and identify protein analytes. The presence of proteins alters the fluorescence properties of the polymers, generating a distinct fluorescence response pattern for a given protein. Linear discriminant analyses accurately differentiate the patterns of 17 proteins at nano<i>-</i> to micromolar concentrations. An identification accuracy of 97% was obtained on the basis of the tests with 68 unknown protein samples from the training set. 2007-08-15 00:00:00 polymer protein analytes 17 proteins fluorescence properties identification accuracy Conjugated PolymersA sensor array fluorescence response pattern protein samples Linear discriminant analyses micromolar concentrations
