Article Abstract
Colloidal photonic crystals (PCs), consisting of highly ordered monodisperse nanoparticles, have been carried out a great deal of research in recent decades due to the attributes of readable signal, easy modification and low cost. With these unique features, colloidal PCs have also gradually become a focus of candidates applied in sensing fields. In this review, an overview of recent advances in colloidal PCs including self-assemblies and sensing applications is illustrated. With respect to the development in self-assemblies of colloidal PCs, the review concentrates on the summary of responsive mechanisms, detection methods, responsive materials, unit cells and fabrication methods. In terms of advances in sensing application of colloidal PCs, various types of sensors are summarized based on the kinds and applications of target analytes. Furthermore, the current limitations and potential future directions of colloidal PCs in self-assemblies and sensing areas are also discussed.

Nanocrystals (NCs) of various compositions have made important contributions to science and technology, with their impact recognized by the 2023 Nobel Prize in Chemistry for the discovery and synthesis of semiconductor quantum dots (QDs). Over four decades of research into NCs has led to numerous advancements in diverse fields, such as optoelectronics, catalysis, energy, medicine, and recently, quantum information and computing. The last 10 years since the predecessor perspective "Prospect of Nanoscience with Nanocrystals" was published in ACS Nano have seen NC research continuously evolve, yielding critical advances in fundamental understanding and practical applications.

By integrating photothermal and chemodynamic properties, Ru-based nanomaterials have emerged as promising agents for tumor therapy. However, their clinical translation is hindered by high systemic toxicity, suboptimal therapeutic efficacy, and compromised chemodynamic performance caused by tumor antioxidant defense mechanisms. A multifunctional therapeutic platform (Ru-PC-PEITC-ALG) was developed through the coordination-driven self-assembly of ruthenium ions with procyanidins (PCs) to form Ru-PC nanoparticles, followed by coencapsulation with phenethyl isothiocyanate (PEITC) in a sodium alginate hydrogel.

Chameleon skins capable of dynamically adjusting and reversibly turning on-off their structural colors have attracted great interest. However, most chameleon-inspired responsive structural color materials (RSCMs) can only mimic the dynamic color and show poor stability, stretchability (strain <68 %), and responsive speed (< 1 nm/ms), significantly restricting their practical applications. Here, force/water-responsive RSCMs that can independently imitate dynamic and on-off structural colors have been fabricated by 1) non-close-assembling silica particles into the 4-hydroxybutyl acrylate (HBA) to generate swellable hydrophilic photonic crystals (PCs), 2) swelling the PCs by HBA, and 3) photopolymerizing swelled PCs.

Nanoparticles (NPs) containing Pb are concerning due to the exceptionally hazardous nature of the element and its widespread use. This study characterizes the weathering of Pb-bearing paint chips (PCs) into Pb-bearing NPs in the surficial soils of Germantown, Philadelphia, USA. The PCs are composed of nano- to micrometer-size engineered particles (EPs) of massicot (PbO, Pb-pigment), Zn-chromates (ZnCrO, primer) and white paint components (rutile, TiO, barite, BaSO, wurtzite, ZnS).
