Abstract

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.

期刊介绍： Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications. Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments. Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
