Thermoresponsive Soft and Self‐Anchoring Cuff Electrode for Chronic Peripheral Interfaces

Advanced Functional Materials, EarlyView.
A novel thermoresponsive, soft and self‐anchoring (TSSA) cuff electrode utilizing shape memory polymers achieves autonomous, sutureless peripheral nerve fixation. Driven by thermally induced pre‐strain and tissue adhesion, the device self‐closes and softens at body temperature, successfully minimizing mechanical mismatch. This adaptive platform ensures

Stability of Medicinal Nanoemulsions to Spaceflight: Insights From the StarMed Experiment

Advanced Healthcare Materials, EarlyView.
Chitosan‐coated melatonin nanoemulsions (MN) recovered from a sounding rocket mission preserve droplet size and controlled‐release behavior, whereas uncoated nanoemulsions show ageing‐driven droplet growth and increased accessible drug fraction. Simple polymer coatings thus enhance the flight resilience of liquid space medicines under cumulative launch
