title: Evaporation-controlled chemical enhancement of SERS using a soft polymer substrate.
abstract: An elusive chemical contribution to SERS is investigated by estimating the chemical coupling strengths through a dynamic relative peak analysis during solvent evaporation from a diluted chemical sample that is drop-deposited on a soft SERS substrate.
