Bio‐Inspired Magnetically Tunable Structural Colors from Elliptical Self‐Assembled Block Copolymer Microparticles

open access: yesAdvanced Functional Materials, EarlyView.
Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

Multivalent Protein Nanorings for Broad and Potent SARS‐CoV‐2 Neutralization

open access: yesAdvanced Healthcare Materials, EarlyView.
A protein‐only, modular multivalent nanoscaffold displaying 20 anchor points, decorated with two different binders (10 of each), targeting the SARS‐CoV‐2 receptor‐binding domain is presented. The construct self‐assembles into stable, biocompatible, homogeneous nanoparticles, exhibit synergistic binding with fM IC50 values. It also detects spike at 9 ng

Enhancing Magnetic Hyperthermia at the Cell Membrane by Anchoring 92R‐Functionalized Magnetic Nanoparticles to Low‐Endocytic CCR9 Surface Receptors

open access: yesAdvanced Healthcare Materials, EarlyView.
We present a strategy to enhance magnetic hyperthermia therapy by modulating nanoparticle–cell interactions. Antibody‐functionalized magnetic nanoparticles targeting the low‐internalizing CCR9 receptor enable spatially controlled membrane anchoring, reducing aggregation and maximizing heat generation under alternating magnetic fields.

Start, Stop, Rewind, Repeat—Cyclic Exposure of Adipose Stromal Cells‐derived Cartilage Organoids to Chondrogenic and Proliferative Cues to Achieve Scaled‐up and Customizable Bone Formation by Endochondral Ossification

open access: yesAdvanced Healthcare Materials, EarlyView.
This study exploits the plasticity of ASCs‐derived cartilage organoids which generate a perichondrial layer of MSCs when exposed to cyclic chondrogenic/proliferative cues. Using these organoids as building blocks, we develop (i) Phalange Shaped Tissue Engineered Cartilage (Pa‐TECs), recapitulating endochondral ossification suitable for the treatment of
