Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents

open access: yesAdvanced Functional Materials, EarlyView.
A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...

Mono‐Material Polydisulfides for Pressure Sensitive Adhesive Tapes With Closed‐Loop Recyclability

open access: yesAdvanced Functional Materials, EarlyView.
A high‐performance pressure‐sensitive adhesive (PSA) tape is developed where both the adhesive layer and plastic backing layer can be recycled back to monomer in a closed‐loop cycle. Both layers of the tape are composed of analogous polydisulfide copolymers using only two unique monomers, thus giving it a mono‐material design and enabling recycling of ...

Multifunctional Neutrophil Nanovesicles Induce Remodeling of Tumor Immune Microenvironment and Synergistic Multimodal Tumor Therapy

open access: yesAdvanced Functional Materials, EarlyView.
Schematic illustration of the engineered RN@FDT for multimodal tumor therapy. a) Fabrication of FD&DOX/TFA‐loaded RGD‐NNV (RN@FDT) and the light‐triggered disassemble of RN@FDT. b) After internalized by tumor cells, RN@FDT are disintegrated under NIR‐II laser irradiation to boost PTT and induce cell apoptosis.
