Nanoprecipitation is a key method to prepare colloids such as liposomes, lipid and polymer nanoparticles. Obtaining a final formulation requires three main steps, the first one consists in mixing the aqueous and organic phases, the solute to be precipitated being added to one of the two phases, according to its solubility. In a second step, the colloidal suspension obtained is concentrated and diafiltrated with an appropriate buffer to remove the solvent required for nanoprecipitation. The last step is sterilization of the resulting concentrated and diafiltrated colloidal suspension. Membrane processes can be used during the three stages. First, a membrane is an option for mixing both phases, although classical micromixers are generally preferred. Tangential flow filtration is used for concentration and diafiltration of the colloidal suspension obtained by nanoprecipitation. Finally, sterile filtration removes potential contaminants before the final use of the colloidal suspension in the delivery of active principle(s). In the following, principles and applications of these three membrane processes are presented and their advantages, limits and some perspectives are discussed.

纳米沉淀法是制备脂质体、脂质和聚合物纳米颗粒等胶体的关键方法。得到最终配方需要三个主要步骤，第一步是将水相和有机相混合，根据溶质的溶解度，将要沉淀的溶质加入到两相中的一个中。在第二步中，将获得的胶体悬浮液浓缩并用适当的缓冲液滤除纳米沉淀所需的溶剂。最后一步是对浓缩和滤过的胶体悬浮液进行灭菌。在这三个阶段中都可以使用膜工艺。首先，膜是混合两相的一种选择，尽管经典的微混合器通常是首选。切向流过滤对纳米沉淀法得到的胶体悬浮液进行浓缩和滤除。最后，在最终使用胶体悬浮液输送活性原理之前，无菌过滤去除潜在的污染物。下面介绍了这三种膜工艺的原理和应用，并讨论了它们的优点、局限性和一些展望。

Evaporation of multicomponent liquids produces complex, far-from-equilibrium phenomena spanning spatial scales from nanometers in aerosols to meters in coating films. A notable outcome of this phenomenon is the evaporation-induced phase separation (EIPS), where the initially homogeneous liquid phase spontaneously separates into multiple phases during the evaporation process. This phenomenon has attracted considerable attention due to its critical role in atmospheric aerosol chemistry, membrane fabrication, biological systems, and advanced materials processing. This review examines the fundamental mechanisms of EIPS, which couple multicomponent evaporation, flow, and phase transitions in multicomponent liquids, highlighting the large spatial scale span and the transient nature of EIPS systems. EIPS-related research and applications across diverse fields will be surveyed, followed by a discussion on open challenges and future opportunities.

多组分液体的蒸发产生复杂的、远离平衡的现象，从纳米级的气溶胶到米级的涂层。这种现象的一个显著结果是蒸发诱导相分离（EIPS），在蒸发过程中，最初均匀的液相自发地分离成多个相。这一现象由于其在大气气溶胶化学、膜制造、生物系统和先进材料加工中的重要作用而引起了相当大的关注。本文综述了多组分蒸发、流动和相变在多组分液体中的耦合作用，强调了EIPS系统的大空间尺度跨度和瞬态性。本次会议将调查不同领域的eips相关研究和应用，然后讨论开放的挑战和未来的机遇。

In this short review, we seek to illustrate how nanoprecipitation can be used as a simple (often one-pot) though powerful method to elaborate nanoparticles with a designed shape or composition. We focus on the case of hybrid organic/inorganic materials, and make the parallel with the more familiar case of polymer-based nanoparticles, leading to either full or core–shell particles. The mechanisms and strategies that allow control of the morphology are discussed. In addition, we connect the concepts of spontaneous emulsification, which was developed in the framework of the nanoprecipitation of organic compounds and polymers, and of co-precipitation related to the synthesis of inorganic nanoparticles.

在这篇简短的综述中，我们试图说明纳米沉淀法如何作为一种简单（通常是一锅）但功能强大的方法来制作具有设计形状或成分的纳米颗粒。我们将重点放在有机/无机杂化材料的情况下，并将其与更熟悉的聚合物基纳米粒子的情况进行比较，从而导致完整或核壳粒子。讨论了允许控制形态的机制和策略。此外，我们将自发乳化的概念（在有机化合物和聚合物的纳米沉淀框架中发展起来）和与无机纳米颗粒合成相关的共沉淀的概念联系起来。

Polymeric colloidal motors are polymer-made tiny machines capable of converting external energy into mechanical motion. Their compositions and architectures have shown a critical effect on controlling the spontaneous creation of energy gradients in response to chemical or physical stimuli for driving autonomous movement in various liquid media or biological microenvironments, holding significant potential for biomedical applications. Advances in nanofabrication have enabled the engineering of polymeric colloidal motors with a variety of compositions and architectures. Recently, nanoprecipitation due to its simple and straightforward process has been exploited to construct polymeric colloidal motors that have the appealing convenience of tuning their compositions, architectures and properties, allowing customization of their motion performance to adapt to various application scenarios. This review highlights the most recent advances in polymeric colloidal motors prepared by nanoprecipitation-based processes. It illustrates the synthesis of polymeric colloidal motors via a programmable solvent-shifting and post-organic solvent removal process, their stimuli-responsive motion behaviors and application performance in biomedical fields. A future perspective on the construction of polymeric colloidal motors through nanoprecipitation is also proposed.

Rod-like chains (RLCs) recently came back in the spotlights due to the development of new systems and applications such as the demand for the replacement of flexible polymers as viscosifiers or the development of suited extra cellular matrices. The advantage of RLC systems is their high mechanical susceptibility. However, the interpretation of the mechanical properties is not straightforward as slow dynamics can be due to extreme sterical hindrance, glassy behavior, or due to attractions that yield gel formation. In this review we identify the open questions for repulsive RLCs and discuss how recent developments in terms of new model systems, experiments, and theory help to identify the huge impact that the morphology of the RLCs can have on the mechanical properties.

棒状链（rlc）最近重新成为人们关注的焦点，这是由于新系统和新应用的发展，例如需要替代柔性聚合物作为增粘剂或开发合适的细胞外基质。RLC系统的优点是机械敏感性高。然而，机械性能的解释并不简单，因为缓慢的动力学可能是由于极端的位阻，玻璃状行为或由于产生凝胶形成的吸引力。在这篇综述中，我们确定了排斥性rlc的开放性问题，并讨论了新模型系统、实验和理论方面的最新发展如何帮助确定rlc的形态对力学性能的巨大影响。

Nanoemulsions are kinetically stable colloidal droplets with exceptional capabilities for encapsulating active compounds and enhancing their bioavailability, making them highly attractive for applications in biomedicine, functional foods, cosmetics and agriculture. In addition to traditional high-energy and low-energy emulsification techniques, Flash Nanoprecipitation (FNP), originally developed for formulating nanodispersions with solid solute, has emerged as a promising and efficient strategy for producing nanoemulsions. FNP features advantages such as controllable droplet size with a narrow size distribution, high loading capacity, enhanced stability due to a kinetically frozen state, and the ability for continuous production. This review summarizes the principles and equipment of FNP, compares its performance with conventional emulsification methods, and highlights recent advances in using FNP for nanoemulsion fabrication, particularly in agricultural applications such as pesticide carriers and functional delivery systems. Finally, we outline future perspectives for the research bridging FNP in nanoemulsion fabrication and applications, including but not limited to, studies on nanodroplet nucleation dynamics, the design of natural stabilizer design, application-driven evaluation, and scaling up for industrial production. This paper provides both mechanistic insights and a technological framework to further advance nanoemulsions and their application in sustainable agriculture.

Nanoprecipitation, the rapid solvent-displacement route to nanoscale phase separation, has matured from a simple batch operation into a versatile platform for nanomaterial synthesis. This review synthesizes recent progress in stimulus-assisted nanoprecipitation, wherein externally applied triggers (ultrasonic, electrical, supergravity, thermal, chemical, and photonic/other stimuli) are integrated with contemporary mixing technologies (batch, flash, microfluidic, membrane, and high-shear reactors) to decouple and selectively control over nucleation, growth kinetics, and assembly processes. These methods allow for the precise tuning of the size, morphology, stability, and functionality of nanoparticles (NPs), thereby broadening their applications in drug delivery, catalysis and materials science. We distill mechanistic principles by which each stimulus alters local supersaturation, chain mobility, interfacial instabilities, or droplet/film microreactor dynamics, and compare advantages and limitations by surveying research works from recent years. We also explore the potential development trends of multiscale coupling models, design rules for stimulus-compatible continuous reactors, and adoption of data-driven optimization frameworks to expand the capabilities of nanoprecipitation for advanced nanomaterial design.
