A device comprising one or more PILs functionalized to
- (1) selectively extract one or more analytes of interest and to allow all other analytes to be removed so that one or more pre-concentrated analytes can be separated, identified and/or quantified;
- and/or
- (2) to selectively extract all other molecules so that the analyte(s) of interest can be removed from other molecules thereby allowing them to be separated, identified, and/or quantified.
