The Core Matters: Aggregation of Neutral Ligand-Coated Nanoparticles in Membranes
The aggregation of gold nanoparticles (AuNPs) influences their optical properties, including localized surface plasmon resonance, through plasmonic coupling between adjacent particles. For hydrophobic AuNPs embedded in lipid membranes, however, the mechanisms governing aggregation remain poorly understood. Although coa...

Competing Colloidal Interactions Govern Polymer Encapsulation of Hydrophobic Iron Oxide Nanoparticles
Control over synthesis conditions is necessary to ensure high loading in polymer-encapsulated iron oxide nanoparticles (P-IONPs) and enable biomedical applications. While flash nanoprecipitation (FNP) is a robust method to fabricate P-IONPs, very little is known regarding the response of hydrophobic IONPs to the change...

Nanoscale Anisotropy of SWCNTs Promotes Enhanced Diffusion in Heterogeneous Complex Fluids
Single-walled carbon nanotubes (SWCNTs) are anisotropic nanoparticles with unique mechanical, electrical, and optical properties. These properties have enabled applications in reinforcing nanocomposites, drug delivery, biosensing, and biomedical imaging, where their performance depends on transport through complex fl...

Hydrodynamic approximation of particle anisometry in solid lipid nanoparticles: Influence of lipid and emulsifier.
Solid lipid nanoparticles (SLNPs) may be used as carriers for lipophilic drugs but also offer potential for the formulation of hydrophilic biomacromolecules via surface adsorption. Regarding the latter, specific surface area and particle anisometry are key parameters, yet quantitative methods to assess them for non-sph...

Controlled Aggregation of Citrate-Stabilized Gold Nanoparticles into Long-Lived Metastable Clusters
The controlled aggregation of plasmonic nanoparticles remains a critical challenge for achieving temporally stable and reproducible colloidal substrates for surface-enhanced Raman scattering (SERS). Here, we show that the antihistamine drug bilastine induces a concentration-dependent, self-limiting aggregation of citra...

Control of Depletion Interactions in Nanoplatelets via Ligand-Shell Engineering to Enhance Colloidal Stability and Nanocomposite Uniformity.
Depletion interactions play a critical role in colloidal stability, yet their behavior in ligand-coated, anisotropic nanocrystals remains poorly understood due to the limitations of hard-particle assumptions at soft interfaces. In two-dimensional (2D) nanoplatelets (NPLs), atomically flat surfaces amplify excluded-volu...
