“…Under optimum conditions, the digital multimeter immunoassay featured good analytical properties toward PSA within the dynamic linear range of 0.02–50 ng·mL –1 at a detection limit of 12.6 pg·mL –1 . A POC electrochemical immunosensor that employed PVDF microparticles coated with streptavidin and AuNPs was developed for the highly sensitive detection of human thyroglobulin . Linear response from 2.0 to 10.0 ng·mL –1 with R 2 of 0.985 was obtained with detection limits of 0.015 ng·mL –1 .…”

From scientific and technological points of view, poly(vinylidene fluoride), PVDF, is one of the most exciting polymers due to its overall physicochemical characteristics. This polymer can crystalize into five crystalline phases and can be processed in the form of films, fibers, membranes, and specific microstructures, being the physical properties controllable over a wide range through appropriate chemical modifications. Moreover, PVDF-based materials are characterized by excellent chemical, mechanical, thermal, and radiation resistance, and for their outstanding electroactive properties, including high dielectric, piezoelectric, pyroelectric, and ferroelectric response, being the best among polymer systems and thus noteworthy for an increasing number of technologies. This review summarizes and critically discusses the latest advances in PVDF and its copolymers, composites, and blends, including their main characteristics and processability, together with their tailorability and implementation in areas including sensors, actuators, energy harvesting and storage devices, environmental membranes, microfluidic, tissue engineering, and antimicrobial applications. The main conclusions, challenges and future trends concerning materials and application areas are also presented.
