PHEMA polymer brush/Ag nanoparticle hybrids for SERS analytics: characterization and performance as versatile sensing substrate
The PHEMA brush architecture offers enhanced control over SERS and acts as a stabilizer towards NPs, distinguishing it from traditional colloidal systems. The introduction of a new synthetic route for NPs reduction inside the polymer matrix - obtained by combining established methodologies for colloidal Ag preparation, - ensures an hybrid structure which is inherently compatible with other analytical techniques. These features significantly broadens the polymer-based system application scope and positions it as a flexible, multifunctional sensing interface.
