Material Coupling in Hybrid Neuromorphic Devices: From Fundamentals to System‐Level Applications

Advanced Functional Materials, EarlyView.
Hybrid neuromorphic devices utilize heterointerfaces between emerging semiconductors, where charge transfer and trapping, ion or defect modulation, and photogating are translated into synaptic functions. This paper discusses coupling strategies that tailor interfacial electronic and ionic properties in organic semiconductors, metal oxides, two ...

Thermally Robust Room‐Temperature Interlayer Excitons in a Hybrid van der Waals Heterostructure

Advanced Functional Materials, EarlyView.
We report an optically active interlayer exciton in a hybrid van der Waals (PEA)2PbBr4/MoS2 heterostructure that remains thermally stable up to 400 K. The emission exhibits polarization anisotropy consistent with an out‐of‐plane optical transition‐dipole component and shows lifetime extension indicative of electron–hole separation.

High‐Throughput DNA Sequence Space Exploration for Carbon Nanotube Biosensor Design

Advanced Functional Materials, EarlyView.
For the screening of next‐generation biosensors, we developed a high‐throughput nanotube platform using covalent DNA‐anchor chemistry to recruit ssDNA motifs via hybridization. Automated liquid handling and spectroscopy enable synthesis of 180 unique sensors and testing of over 540 sensor/analyte conditions in three days.

Human iPSC‐Derived Tissue‐Engineered Nigrostriatal Pathway for Chronic Restoration of Dopaminergic Axon Tracts in a Rat Parkinson's Model

Advanced Healthcare Materials, EarlyView.
Inspired by conventional cell therapy and emerging bioengineering approaches, the tissue‐engineered nigrostriatal pathway (TE‐NSP) has an anatomically‐inspired design comprising a population of human dopaminergic neurons with unidirectional, long‐projecting axon tracts.
