“…The charged AuNPs attract the oppositely charged counterions surrounding the NPs, yielding a neutrally charged electric double layer. The electric double layer is critical for the electrostatic stabilization of AuNPs and comprises three parts: surface charge, Stern layer, and diffuse layer (see Figure A). − The electrical potential within the electric double layer of AuNPs has its maximum value at the Stern layer. However, as the distance from the surface increases, this potential decreases, reaching zero at the boundary of the electric double layer.…”

Gold nanoparticles (AuNPs) are used in various biological applications because of their small surface area-to-volume ratios, ease of synthesis and modification, low toxicity, and unique optical properties. These properties can vary significantly with changes in AuNP size, shape, composition, and arrangement. Thus, the stabilization of AuNPs is crucial to preserve the properties required for biological applications. In recent years, various polymer-based physical and chemical methods have been extensively used for AuNP stabilization. However, a new stabilization approach using biomolecules has recently attracted considerable attention. Biomolecules such as DNA, RNA, peptides, and proteins are representative of the biomoieties that can functionalize AuNPs. According to several studies, biomolecules can stabilize AuNPs in biological media; in addition, AuNP-conjugated biomolecules can retain certain biological functions. Furthermore, the presence of biomolecules on AuNPs significantly enhances their biocompatibility. This review provides a representative overview of AuNP functionalization using various biomolecules. The strategies and mechanisms of AuNP functionalization using biomolecules are comprehensively discussed in the context of various biological fields.

“…In Table 2, some parameters related to the electrical double layer thickness are compared to the sizes obtained in the DLS analysis. According to Debye-Hückel theory, an electrical double layer is formed whenever a solid-liquid interface exists as shown in Figure 6 [28]. These are structures that appear in the solid surface, since the ions are ordered around it in the first layer due to surface charge phenomena and in the second layer because of the attraction of these first layer ions, electrically screening them.…”

“…Polymer blends are multi-materials consisting of a predominantly present polymer, which is often used as a matrix, and one or more materials, which are continuously or discontinuously dispersed within [ 1 ]. The properties of the blend system depends on several parameters, e.g., the matrix polymer, the dispersed polymer, the dispersion inside the matrix polymer, the effects at the polymer and the spatial arrangement of the materials with respect to each other [ 2 , 3 ] as well as on the properties of further filler materials within the blend.…”

Control of Crystallization of PBT-PC Blends by Anisotropic SiO2 and GeO2 Glass Flakes

Polymer composites and blend systems are of increasing importance, due to the combination of unique and different material properties. Blending polybutylene terephatalte (PBT) with polycarbonate (PC) has been the focus of attention for some time in order to combine thermo-chemical with mechanical resistance. The right compounding of the two polymers is a particular challenge, since phase boundaries between PBT and PC lead to coalescence during melting, and thus to unwanted segregation within the composite material. Amorphization of the semi-crystalline PBT would significantly improve the blending of the two polymers, which is why specific miscibility aids are needed for this purpose. Recent research has focused on the functionalization of polymers with shape-anisotropic glass particles. The advantage of those results from their two-dimensional shape, which not only improves the mechanical properties but are also suspected to act as miscibility aids, as they could catalyze transesterification or act as crystallization modifier. This work presents a process route for the production of PBT-PC blends via co-comminution and an in-situ additivation of the polymer blend particles with anisotropic glass flakes to adjust the crystallinity and therefore enhance the miscibility of the polymers.
