Versatile SPME-SERS fiber based on Ag-nanoaggregate-decorated porous polymer for screening organic contaminants.
This study presents a versatile solid-phase microextraction-surface-enhanced Raman spectroscopy (SPME-SERS) fiber for qualitative screening of organic contaminants across different sample phases. The fiber was fabricated by incorporating polydimethylsiloxane-modified Ag-nanoaggregates (AgNA) into a porous poly(2,6-diph...
