The emergence of antimicrobial resistance is considered a public health problem due to the overuse and misuse of antibiotics which are losing e\ufb03cacy toward an increasing number of microorganisms. Advanced antimicrobial strategies via development of alternative drugs and materials able to control microbial infections, especially in clinical settings, are urgently needed. In this work, nanocomposite \ufb01lms were developed from piezoelectric PVDF polymer \ufb01lled with nickel nanowires to control and enhance the antimicrobial activity via the application of a magnetic stimulus. The material was achieved through crystallization of PVDF upon incorporation of anisotropic and negatively charged Ni nanowires in the polymeric matrix. The nanocomposites have shown to possess antimicrobial properties which was considerably boosted through the application of a magnetic \ufb01eld. More than 55% of bacterial growth inhibition was obtained by employing controlled dynamic magnetic conditions compared to only 25% inhibition obtained under static conditions. This work demonstrates a proof-of-concept for materials able to boost on demand their antimicrobial activity and opens the room for applications in novel medical devices with improved control of healthcare-associated infections.<\/p>\n
