摘要

具有长表面突起的微粒，要么是刚性的尖刺，要么是柔性的枝晶，代表了一类独特的胶体材料。它们的化学和结构特征使其特性和功能与类似形状的纳米颗粒有根本的不同，在药物输送、生物膜破坏和粘合技术方面具有广泛的应用。它们独特的尖状或树突状形态改变了粒子间的相互作用，并调节了粒子与环境的相互作用。合成这些粒子本身就具有挑战性，因为胶体粒子自然地倾向于光滑的表面，以最小化表面能。本文综述了主要的合成策略，包括种子生长、乳液模板合成和湍流剪切下的聚合物沉淀。我们描述了通过这些过程产生的粒子及其应用，并讨论了这一新兴领域未来的挑战和机遇。

Spiky and Dendritic Microparticles: Design, Synthesis, and Emerging Applications

Microparticles with long surface protrusions, either as rigid spikes or flexible dendrites, represent a unique class of colloidal materials. Their chemical and structural features give rise to properties and functions that differ fundamentally from those of similarly shaped nanoparticles, with applications in drug delivery, biofilm disruption, and adhesive technologies. Their distinctive spiky or dendritic morphologies alter interparticle interactions, and regulate particle–environment interactions. Synthesizing these particles is inherently challenging, as colloidal particles naturally favor smooth surfaces to minimize surface energy. This review highlights key synthetic strategies, including seeded growth, emulsion-templated synthesis, and polymer precipitation under turbulent shear. We describe the particles produced via these processes and their applications, and discuss future challenges and opportunities in this emerging field.

期刊介绍： The journal Chemistry of Materials focuses on publishing original research at the intersection of materials science and chemistry. The studies published in the journal involve chemistry as a prominent component and explore topics such as the design, synthesis, characterization, processing, understanding, and application of functional or potentially functional materials. The journal covers various areas of interest, including inorganic and organic solid-state chemistry, nanomaterials, biomaterials, thin films and polymers, and composite/hybrid materials. The journal particularly seeks papers that highlight the creation or development of innovative materials with novel optical, electrical, magnetic, catalytic, or mechanical properties. It is essential that manuscripts on these topics have a primary focus on the chemistry of materials and represent a significant advancement compared to prior research. Before external reviews are sought, submitted manuscripts undergo a review process by a minimum of two editors to ensure their appropriateness for the journal and the presence of sufficient evidence of a significant advance that will be of broad interest to the materials chemistry community.
