“…It was used to monitor organic-inorganic hybrid films growth by recording the quartz crystal’s frequency decrease during each adsorption cycle. QCM sensors were used to study the adsorption of Keggin phosphotungstic acid POM onto a copolymer-coated QCM as a function of time at several pH conditions ( Raj et al, 2015 ). Also, the organic-inorganic hybrid polyoxometalate (NBu 4 ) 3 [PW 11 O 39 {(SiC 6 H 4 NH 2 ) 2 O}], carrying two amine functions, allowed the construction of an ordered array of amine groups on the sensor surface for benzo [a]pirene detection.…”

Polyoxometalates (POMs) are a class of metal oxide complexes with a large structural diversity. Effective control of the final chemical and physical properties of POMs could be provided by fine-tuning chemical modifications, such as the inclusion of other metals or non-metal ions. In addition, the nature and type of the counterion can also impact POM properties, like solubility. Besides, POMs may combine with carbon materials as graphene oxide, reduced graphene oxide or carbon nanotubes to enhance electronic conductivity, with noble metal nanoparticles to increase catalytic and functional sites, be introduced into metal-organic frameworks to increase surface area and expose more active sites, and embedded into conducting polymers. The possibility to design POMs to match properties adequate for specific sensing applications turns them into highly desirable chemicals for sensor sensitive layers. This review intends to provide an overview of POM structures used in sensors (electrochemical, optical, and piezoelectric), highlighting their main functional features. Furthermore, this review aims to summarize the reported applications of POMs in sensors for detecting and determining analytes in different matrices, many of them with biochemical and clinical relevance, along with analytical figures of merit and main virtues and problems of such devices. Special emphasis is given to the stability of POMs sensitive layers, detection limits, selectivity, the pH working range and throughput.

“…AFM has emerged as an extremely versatile tool to investigate the threedimensional morphology of particles with sub-nanometer spatial resolution [15]. In catalysis, AFM has been already used to image the nanoscale organization of catalytic nanoparticles on various systems such as supported metal catalysts [16][17][18], and redox enzymes [19]. The analysis consists on scanning the sample surface, placed on a piezoelectric scanner, with a sharp tip-mounted cantilever.…”
