Brachyury‐Activated Fucoidan Hydrogel Microspheres Rejuvenate Degenerative Intervertebral Discs Microenvironment

open access: yesAdvanced Science, EarlyView.
This study describes the creation of injectable Brachyury (Bry) mRNA‐loaded Fucoidan‐functionalized GelMA hydrogel microspheres (BLNP@GF). These microspheres efficiently suppress inflammation, enhance extracellular matrix (ECM) synthesis in degenerated nucleus pulposus cells, and mitigate intervertebral disc degeneration (IVDD) in rat models.

Nasal Delivery of Engineered Exosomes via a Thermo‐Sensitive Hydrogel Depot Reprograms Glial Cells for Spinal Cord Repair

open access: yesAdvanced Science, EarlyView.
Engineered macrophage‐derived exosomes overexpressing GNA12 and GNA13 reprogram glial cells to promote neuroprotection and neural regeneration following SCI. A chitosan‐based thermosensitive hydrogel enables sustained intranasal exosome delivery, bypassing systemic barriers and enhancing therapeutic efficacy.

Stiffness‐Tunable Neurotentacles for Minimally Invasive Implantation and Long‐Term Neural Activity Recordings

open access: yesAdvanced Science, EarlyView.
A hydraulically actuated “Neurotentacle” probe offers tunable stiffness for precise implantation into the deep brain without rigid shuttles or dissolvable coatings. It stiffens during insertion to penetrate tissue and softens afterward to minimize damage and enable stable long‐term recordings.

Spin‐Orbit Angular Momentum Conversion in Coupled Nonparaxial Bessel Acoustic Vortices

open access: yesAdvanced Science, EarlyView.
This study gives a formulaic description of the spin‐orbit angular momentum (AM) conversion in coupled fields of two nonparaxial Bessel acoustic vortices. Experimental results of wave field measurements provide compelling evidence for spin‐orbit AM conversion via passive artificial structures.
