Biomimetic Core–Shell Liposome Nanoparticles Deplete Lipoproteins and Enhance the Purity of Extracellular Vesicles from Human Blood

open access: yesAdvanced Functional Materials, EarlyView.
Lipoprotein‐mimicking nanoparticles (SL‐NPs), comprising Fe3O4@SiO2 cores coated with liposomal bilayers, selectively capture lipoproteins through protein corona formation. The resulting SL‐NP‐lipoprotein complexes can be removed by low‐speed centrifugation, thereby enhancing the purity of small extracellular vesicles (sEVs) isolated from human serum ...

Silicone Breast Implants as a Model System for Understanding Polymer Permeation in Soft Materials In Vivo

open access: yesAdvanced Healthcare Materials, EarlyView.
Silicone breast implants are presented as a model system for understanding polymer permeation in vivo. Rather than representing material failure, “gel bleed” emerges from solution–diffusion transport‐mediated. By integrating polymer architecture, physicochemical transport, and biointerfacial processes, this review provides a unified framework that ...

Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

open access: yesAdvanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.

Covalent Attachment of Quaternary Ammonium Group to Geopolymer Surface With Silane Coupling Agent to Enable Simultaneous Adsorption of Cations and Anions

open access: yesAdvanced Materials Interfaces, EarlyView.
Modification of geopolymer surface with a silane coupling agent containing quaternary ammonium group enables the development of dual‐functioning ion exchanger for both cations and anions. In the present study, the performance of this material was demonstrated for the uptake of ammonium and nitrate from water.
