The Distribution of Complement Proteins in Soft and Hard Coronas Impacts Macrophage Uptake of Nanoparticles

open access: yesAdvanced Healthcare Materials, EarlyView.
Protein corona plays a critical role in the biological behavior of nanoparticles. This study investigates the distribution of complement proteins in soft corona and their impact on the macrophage uptake of polymer nanoparticles. It underlines the significance of soft corona investigation for understanding in vivo performance of nanomedicines.

Effective Penetration of the Oxidized Keratin‐Rebonding Materials Into Hair Shafts Based on Charge Conversion

open access: yesAdvanced Healthcare Materials, EarlyView.
We have developed a smart hair‐repair ingredient based on β‐carboxylic acid amide that undergoes negative‐to‐positive charge conversion under mildly acidic conditions. The initial negative charge facilitates deep penetration into the hair fiber, while the subsequent positive charge enables re‐bonding with sulfonate groups in damaged hair keratin.

SiO2‐CaOCME/Poly(Tetrahydrofuran)/Poly(Caprolactone) 3D‐Printed Scaffolds Drive Human‐Bone Marrow Stromal Cell Osteogenic Differentiation

open access: yesAdvanced Healthcare Materials, EarlyView.
3D printed hybrid scaffolds combining bioactive silica–calcium chemistry with elastic polymers guide human bone stem cells to form bone. The scaffolds support cell survival, organization, and invasion while releasing osteogenic ions. Together, architecture and composition drive bone‐specific gene expression, extracellular matrix organization, and ...

IL‐2 Free Expansion of T Cells with Immunofilaments

open access: yesAdvanced Healthcare Materials, EarlyView.
Ratio and density of stimulatory αCD3 and αCD28 mAb on immunofilaments (IF) influence T cell expansion, cytokine production, and effector phenotype. Moreover, IL‐2 supplementation is not necessary with optimal performing IFs, which leads to simpler culture conditions, and negative side effects of IL‐2 supplementation are reduced.

Evaluating Cytocompatibility of Corynebacterium glutamicum‐poly Vinyl Alcohol Living Biomaterials for Ocular Use

open access: yesAdvanced Healthcare Materials, EarlyView.
In ophthalmology, living biomaterials such as living contact lenses appear promising for sustained drug delivery or biosensing. The cytocompatibility of Cg‐PVA hydrogels, developed as a model living contact lens, is investigated with the ocular surface, showing their potential translation to the clinic.
