Fluorescence based detection is applied across various fields, including medical diagnostics and environmental sensing. A key challenge in these technologies lies optimizing sensitivity through enhancement of the fluorescence signal. In this study, we demonstrate that combining piezoelectric plasmonic processes increases yield. Piezoelectric poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), utilized as an external electric field modulator to produce a reliable reproducible InP/ZnS quantum dots approaching single nanoparticle level. The relationship between force response both experimentally quantified theoretically modeled dependence on excitation wavelength PVDF-HFP substrate topography elucidated. Furthermore, by magnitude order for DNA hybridization assay gold-coated demonstrated, highlighting practical applicability approach biosensing.
