“…The radiolabelling of the NPs with a direct method can also be performed with a short incubation between SnCl 2 and the NPs, followed by the addition of 99m Tc in the solution. This method was used to radiolabel several types of NPs: octreotide NPs, cerium oxide NPs (CeO 2 -NPs), mesoporous silica NPs, poly-γ-glutamic acid NPs conjugated with folic acid, carbon-based mesoporous NPs, zirconium NPs, serum albumin nanoparticles, polymeric NPs, and dendrimer glycoconjugate [ 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. All the studies showed a high final LE, but the formation of radiocolloids often requires further purification of the solution.…”

The use of nanoparticles (NPs) is rapidly increasing in nuclear medicine for diagnostic and therapeutic purposes. Their wide use is due to their chemical–physical characteristics and possibility to deliver several molecules. NPs can be synthetised by organic and/or inorganic materials and they can have different size, shape, chemical composition, and char. These factors influence their biodistribution, clearance, and targeting ability in vivo. NPs can be designed to encapsulate inside the core or bind to the surface on several molecules, including radionuclides, for different clinical applications. Either diagnostic or therapeutic radioactive NPs can be synthetised, making a so-called theragnostic tool. To date, there are several methods for radiolabelling NPs that vary depending on both the physical and chemical properties of the NPs and on the isotope used. In this review, we analysed and compared different methods for radiolabelling NPs for single-photon emission computed tomography (SPECT) use.

“…Ferroelectric (FE) materials, due to the distinctive properties such as large nonlinear optical coefficient, high permittivity and switchable spontaneous polarization, [1,2] have been put in use in numerous fields, i. e. electronic memory, thermosensitive resistor, piezoelectric sensor, etc. [3][4][5] The polarization in FE materials can induce different types of charge on opposite surfaces, and then the charged surfaces create a so-called internal electric field (E-field), which can efficiently separate photogenerated charge carries in FE materials and increase the lifetime of electron-hole pairs, thus consequently enhancing photochemical reactions. [6] Particularly, BaTiO 3 (BTO), due to its large ferroelectric polarization strength, chemical stability and biosafety, [7,8] has been treated as one of the ideal photocatalytic materials.…”

[5,9] For example, BTO has displayed unique photocatalytic performance in various areas such as hydrogen production, degradation of dyes, bacterial disinfection and so on. [10][11][12] However, the band gap of BTO is ~3.2 eV, which make it be responsive only under irradiation of ultraviolet light.…”

The SPR‐generated electric field (E‐field) intensities around a Ag nanocube (NC) before and after covered by BaTiO3 (BTO) layer (BTO@Ag NC) were calculated. It was observed that the theoretical E‐field intensities were reduced on BTO@Ag NC, thus suggesting inferior catalytic activities under visible light illumination. However, BTO@Ag NCs experimentally displayed better photocatalytic performance than that of Ag NCs under illumination at 633 nm, both in ambient argon (Ar) and in ambient air, where PATP molecules were used to probe the conversion. The mechanism can be attributed to the surface polarization of BTO layer trigged by SPR effect of Ag core. The oscillation of free electrons in Ag core aroused appearance of surface polarization charge on ferroelectric (FE) BTO surface, which resulted in the enhanced catalytic properties of BTO@Ag NCs. Therefore, our finding may provide a novel method to enhance visible‐light responsive photocatalytic activity of wide bandgap FE materials by depositing them on plasmonic metal nanostructures.

“…PVDF is currently recognized as a piezoelectric polymer material. 10–12 The polar polymer PVDF has three types: α-, β-, and γ-, of which, the β-phase (β-PVDF) has the highest polarity, and its dipoles are aligned in the same direction (ferroelectric properties). Song et al 13 reported that the polarization of PVDF as a binder had an effect on improving lithium ion migration.…”

Barium titanate (BaTiO3) is a typical perovskite-type oxide with high dielectric constant, low dielectric loss, and excellent ferroelectric, piezoelectric, pyroelectric, and other properties. In view of the low photogenerated electron-hole separation efficiency of T-BT itself, it is proposed to prepare nanocomposites with good catalytic performance by compound modification with Ag. Considering repeated use, on the basis of powder catalysis, a porous block is prepared by compounding powder and organic polymer PVDF. In this study, the t-BaTiO3/Ag/β-PVDF composite material with porosity of ∼70.4% was prepared with the raw material of PVDF and piezoelectric t-BaTiO3/Ag. The mechanical and piezoelectric photocatalytic properties of the composite material was studied systematically. The piezoelectric coefficient d 33 is 1.44 pC/N which can be explained by COMSOL simulation calculation. Moreover, the compressive strength is 1.76 MPa. The degradation MO and RhB results indicated that t-BaTiO3/Ag/β-PVDF composite material had good degradation and cycle stability.
