    摘要:
    通过在聚二乙炔胶束中络合氯化铜来开发胶体催化剂。通过提供合适的配体环境,将后者设计为容纳和稳定铜盐。胶束因其中心疏水核而不仅可以在水中分散,还可以在催化剂附近浓缩试剂,因此被誉为纳米反应器,可以促进水中的惠斯根环加成反应。发现该系统可在多种基材上运行并在可持续条件下有效运行。

Upon UV irradiation, a reversible gel–sol transition was observed, resulting from the photoswitching of the azobenzene unit from the stretched trans form to the compact, metastable cis form. Our gels were shown to enable spatio-temporal control of the adhesion and release of the lectin Concanavalin A, demonstrating potential use as regenerable biomaterials to fight against infections
    近年来,刺激响应性超分子生物材料领域迅速发展,在癌症治疗诊断、组织工程和催化等多个领域具有潜在的应用前景。然而,设计具有预定分层自组装的分子材料以控制最终纳米结构的尺寸、形态、表面化学和响应性仍然是一个重大挑战。在这项研究中,我们提出了一种不同的合成方法,用于从结构相关的重氮苯/二乙炔糖脂制造球形胶束和基于一维糖纳米管的功能性光响应凝胶。使用 NMR、TEM 和 SEM 对所得纳米结构进行了表征,证实在凝胶和溶液状态下均形成球形和管状纳米结构。在紫外线照射下,观察到可逆的凝胶-溶胶转变,这是由于偶氮苯单元从拉伸的反式形式到紧凑的亚稳态顺式形式的光转换所致。我们的凝胶能够对凝集素伴刀豆球蛋白 A 的粘附和释放进行时空控制,证明了其作为可再生生物材料对抗毒素和病原体感染的潜在用途。此外,我们的胶束和凝胶作为纳米容器进行了评估,用于装载和控制释放疏水性染料和抗肿瘤药物,表明它们可能用作智能治疗诊断药物输送系统。
  • Supramolecular Diversity through Click Chemistry: Switching from Nanomicelles to 1D-Nanotubes and Tridimensional Hydrogels
    作者:Mohyeddin Assali、Juan-José Cid、Inmaculada Fernández、Noureddine Khiar

    The size and shape of nanoparticles are of prominent importance for their biological activities and for their application as smart drug delivery systems. Thus, synthetic designs allowing divergent synthesis of nanoscale materials with controlled size, morphology, and surface chemistry are currently highly desirable, but they remain a major challenge. Herein, we report a simple method for the creation of supramolecular diversity from structurally related diacetylenic-based glycolipids. We have found that neoglycolipids with an amide function between the hydrophilic and hydrophobic part of the amphiphile afford tridimensional micelles, while those having a triazole self-organize into 1D-nanotubes. Additionally, at higher concentrations, the clicked amphiphiles form hydrogels through three-dimensional networks of bundled nanotubes. Photopolymerization of the obtained nanomaterials leads to the formation of conjugated polydiacetylene backbone of alternating enyne groups, which rigidify glyconanomaterial structures enhancing their physical stability. The obtained nanostructures were extensively characterized using transmission electron microscopy (TEM), scanning electron microscopy (SEM), and atomic force microscopy (AFM) techniques, enabling the confirmation of the formation of tubular structures in water for all triazolo-substituted neoglycolipids and micellar structures for the glycolipid containing an amide group. This fact refutes the so-called isosteric character of 1,2,3-triazole and amide groups, at least, at the supramolecular level and point out to the possibility of using the CuAAC between azides and alkynes to create supramolecular diversity at the nanoscale. The functionality of the gel was, moreover, evaluated as a nanocontainer for the incarceration and controlled release of the antitumoral topotecan.
