Nanoporous Microelectrodes for Neural Electrophysiology Recordings in Organotypic Culture

Advanced Materials Technologies, EarlyView.
The highly porous microelectrodes have been designed and printed on culture membranes, allowing to record electrophysiological neural activity for rodent brain slices. To keep the biocompatible nanoporous structure, the microelectrodes and insulative layer are fabricated on the bottom of culture membranes with only small connector pads added on the top.

Dynamic Decoration of DNA Scaffolds for High‐Resolution Cancer Cell Subtyping

Advanced Science, EarlyView.
This study presents a dual‐mode imaging platform that utilizes self‐assembly and disassembly of DNA scaffolds for high‐resolution cancer cell detection. The structural rigidity of DNA scaffolds effectively prevents cellular internalization for over 300 min.

Review of Memristors for In‐Memory Computing and Spiking Neural Networks

Advanced Intelligent Systems, EarlyView.
Memristors uniquely enable energy‐efficient, brain‐inspired computing by acting as both memory and synaptic elements. This review highlights their physical mechanisms, integration in crossbar arrays, and role in spiking neural networks. Key challenges, including variability, relaxation, and stochastic switching, are discussed, alongside emerging ...

Nullification functors and the homotopy type of the classifying space for proper bundles [PDF]

, 2005
Let G be a discrete group for which the classifying space for proper G-actions is finite-dimensional. We find a space W such that for any such G, the classifying space PBG for proper G-bundles has the homotopy type of the W-nullification of BG.
