Recent Advances in Functional Nanoparticle Assemblies

Abstract

Assemblies of colloidal nanoparticles (NPs) into various functional superstructures, such as ordered or nonordered, microscopic or macroscopic, and templated or self‐supported, have recently attracted a lot of research interest. The continuous development of colloidal nanoparticle synthesis enables a fine‐tuning of the structure and properties of such functional superstructures leading to numerous new applications. Herein, it is aimed to summarize a variety of assemblies based on ordered self‐assembled NPs, e.g., stacked nanoplatelets, and nonordered self‐assembled NPs, e.g., nanoparticle‐based aerogels and cryoaerogels, systems ranging from the microscopic to the macroscopic range. Depending on the materials of the nanoparticle building blocks used, e.g., metallic, magnetic, semiconducting, or their combination in hybrid systems, both ordered and nonordered assemblies yield interesting properties for a wide variety of applications, such as catalysis, photocatalysis, or sensing, which are highlighted and discussed.

Activated aggregation‐induced emission therapeutics agents for triggering regulated cell death

“…[ 159 ] These functional moieties, including enzymes, antibodies, aptamers, small molecules, and other targeting molecules, can be attached to drug carriers via various interactions, recognizing receptors expressed in cancer cells or the tumor microenvironment. [ 160–162 ] In recent years, the emergence of cell‐mediated drug delivery systems as promising strategies has occurred. [ 163 ] By leveraging unique cell properties such as extended blood circulation, abundant surface ligands that potentially enable specific hitchhiking, targeted tumor cell interactions, and adaptable morphology that navigates biological barriers, these systems optimize therapeutic outcomes while minimizing side effects.…”
