Cortical Response to Acute Implantation of the Utah Optrode Array in Macaque Cortex

open access: yesAdvanced Healthcare Materials, EarlyView.
Delivering light deep into the brain over a large volume while causing minimal tissue damage is a major challenge for non‐human primate optogenetics. This study evaluates Utah Optrode Array designs in vivo, revealing how changes in shank geometry, surface texture, and insertion parameters minimize acute damage—offering a path toward high‐precision ...

Facile Deep Brain Electrode Coating with MXene for Improved Electrode Performance

open access: yesAdvanced Healthcare Materials, EarlyView.
Facile dip‐coating of commercial carbon fiber electrodes with Ti3C2Tx MXene improves electrical conductivity, reduces impedance, and enables single‐neuron recordings in the rat hippocampus over four weeks. The coating maintains biocompatibility, minimizes inflammation, and remains MRI‐compatible.

A Human Neural Tube Model Using 4D Self‐Folding Smart Scaffolds

open access: yesAdvanced Healthcare Materials, EarlyView.
Induced pluripotent stem cells (iPSCs) exhibit features comparable to the inner cell mass of the human embryo. iPSCs are applied to a novel self‐folding 4D‐Neural Tube (4D‐NT) structure that mimics the neurulation process. This 4D‐NT model recapitulates early events of human neural development and represents a platform to explore neurodevelopmental ...

A Novel Brain Penetrable Nanocarrier Delivers Brain‐Derived Neurotrophic Factor to Treat Alzheimer's Disease

open access: yesAdvanced Healthcare Materials, EarlyView.
A novel blood‐brain barrier‐penetrating terpolymer nanoparticle to deliver brain‐derived neurotrophic factor (BDNF) for the treatment of Alzheimer's disease (AD) is designed. The BDNF‐TPN significantly enhances BDNF accumulation in the brain following intravenous injection, reduces apoptosis and neuroinflammation, thus promoting neuronal survival and ...

Translational Considerations for Injectable Biomaterials and Bioscaffolds to Repair and Regenerate Brain Tissue

open access: yesAdvanced Healthcare Materials, EarlyView.
The repair and regeneration of brain tissue faces both biological and technical challenges. Injectable bioscaffolds offer new opportunities to stimulate tissue regrowth in the brain by recruiting neural stem cells. Here, the translational issues are reviewed that need to be address to advance this promising new therapeutic approach from the bench to ...
