Dynamic Bonds Enable Repair and Reprocessing of Glycol‐Modified PET

open access: yesAdvanced Functional Materials, EarlyView.
Dynamic hindered urea bonds enable rapid healing in glycol‐modified PET‐based polyurethanes. Tuning the hindered‐amine content allows these polymers to balance mechanical integrity with fast repair, achieving complete scratch disappearance in 30 s at 130°C.

Lysosome‐Acidifying Nanoparticles Rescue A30P α‐Synuclein Induced Neuronal Death in Cellular and Drosophila Models of Parkinson's Disease

open access: yesAdvanced Healthcare Materials, EarlyView.
Lysosome‐targeted acidic nanoparticles based on a biodegradable poly(ethylene tetrafluorosuccinate‐co‐succinate) copolymer are engineered to restore impaired lysosomal acidification through pH‐responsive intracellular degradation. Localized acid release enhances autophagic proteolysis, reduces α‐synuclein accumulation, and preserves dopaminergic neuron

Softening Shape Memory Polymer Substrates for Bioelectronic Devices With Improved Hydrolytic Stability

open access: yesFrontiers in Materials, 2018
Candidate materials for next generation neural recording electrodes include shape memory polymers (SMPs). These materials have the capability to undergo softening after insertion in the body, and therefore reduce the mismatch in modulus that usually ...
