Microbubble Shell Stiffness Engineering Enhances Ultrasound Imaging, Drug Delivery, and Sonoporation

open access: yesAdvanced Materials, EarlyView.
 Shell‐engineered poly(alkyl cyanoacrylate) microbubbles with tunable stiffness improve ultrasound imaging and therapy. Adjusting the length of the alkyl chain and the glass transition temperature maintains a narrow microbubble size distribution while enhancing drug loading, sonoporation and the acoustic response.

Supramolecular Interface Engineering via Interdiffusion for Reusable and Dismantlable Polymer Adhesion

open access: yesAdvanced Materials, EarlyView.
Reversible adhesion via host–guest complex formation at the polymer interface is achieved by externally controlling the complexation through applied stimuli. Neutron reflectometry analysis of the adhesion interface revealed that the presence of host–guest complexes hinders the polymer interdiffusion by despite promoting adhesion strength.

Unfolding and Degradation of Micellar Immunodrug Carriers Derived From End Group Modified Aliphatic Poly(Carbonate)s with Acid‐Responsive Ketal Side Groups

open access: yesAdvanced Materials, EarlyView.
An acid‐responsive polymeric micelle system based of aliphatic poly(carbonate)s with benzyl ketal side chains is designed for targeted immunodrug delivery. It can disassemble in endosomal environments, enabling site‐specific immunoactivation and enhanced biodegradability.

Sustainable Self‐Healing of Perovskite Solar Cells Using Dendrimers as Volatile Reservoirs

open access: yesAdvanced Materials, EarlyView.
Sustainable self‐healing perovskite solar cells (PSCs) are developed through the incorporation of dendrimers with unique molecular structures and appropriately placed functional groups. Notably, even after subjecting ten harsh degradation and recovery cycles, these PSCs maintain 90% of their initial power conversion efficiency (>26%).
