“…Specifically, the PAE-NC was synthesized using DFBN and PPL as monomers via the nucleophilic substitution polycondensation that can be easily scaled up according to Figure 1A . In addition, we attempted to transfer the pendent nitrile of PAE-NC into reactive groups, since the alkaline hydrolysis of nitrile leads to the generation of various reactive groups ( Eloy and Lenaers, 1962 ; Yanaranop et al, 2016 ; He et al, 2021a ). According to the 1H NMR spectra in Figure 1B , the PAE-NC was successfully synthesized and its chemical structure was steadily modulated along with hydrolysis treatment.…”

Emulsion confinement self-assembly of block copolymer has witnessed increasing research interest in the recent decade, but the post-functionalization and application of the resultant polymeric micro/nano-particles are still in their infancy. In this work, a super-engineering polyarylene ether containing pendent nitrile and carboxyl (PAE-NC) has been synthesized and converted into polymeric microparticles for macromolecular enrichment via emulsion confinement self-assembly and subsequent surface modification. Moreover, the encapsulation capacity of PAE-NC was evaluated using hydrophobic fluorescent quantum dots (QD) as a functional probe. Particularly, we found that both the as-synthesized PAE-NC and its hydrolyzed derivatives could be converted into microparticles via emulsion confinement self-assembly. Furthermore, the co-self-assembly of red-emitting QD and PAE-NC enables the phase transfer of hydrophobic QD into hydrophilic luminescent microparticles with the persisted fluorescence emission. Based on these results, the current PAE-NC would be served as a versatile and robust matrix to fabricate advanced microparticles or microcapsules for various applications.

The hydrophobic nature of synthetic polymers poses a substantial barrier since it limits cell-seeding and proliferation scaffold performance. To overcome this challenge, the present research attempts to employ in-situ UV electrospinning and plasma surface modification techniques to fabricate a three-dimensional PAN/PVA-gelatin scaffold. The proposed scaffold holds great potential in mitigating hydrophobicity limitations, thereby facilitating enhanced cell adhesion and proliferation. The SEM results indicated that exposure to UV irradiation resulted in the formation of wavy shapes in the PAN microstructures and crosslinking between fibers within the scaffold. Moreover, plasma treatment induced the formation of pores on the PAN surface, with an average diameter of 43 µm, corresponding to the size range of mouse fibroblast cells. Furthermore, the plasma treatment provided roughness augmentation of the scaffold surface, which played a crucial role in enhancing cell adhesion and elongation on the modified scaffold surface. Comparatively, the plasma-modified scaffolds exhibited a higher proportion of viable cells than the unmodified scaffolds (p < 0.05). Moreover, the implementation of perforations in the PAN layer via plasma treatment reduced the number of necrosis cells in comparison to the other samples. In contrast, the unmodified scaffold showed a higher percentage of apoptosis cells (p < 0.05).
