Scalable, Modular Three-Dimensional Silicon Microelectrode Assembly via Electroless Plating

Micromachines, 2018
We devised a scalable, modular strategy for microfabricated 3-D neural probe synthesis. We constructed a 3-D probe out of individual 2-D components (arrays of shanks bearing close-packed electrodes) using mechanical self-locking and self-aligning ...

Microelectrodes in solid state ionics

, 2003
The great potential of microelectrode measurements in several fields of solid state ionics is discussed and exemplified: (i) Microelectrodes are perfectly suited to investigate inhomogeneous bulk conductivities in ionic solids. This is demonstrated for a

Mesoporous PU/PEDOT:PSS Electrodes Reveal Population‐Level Stochastic Bioelectrical Dynamics in Marine Diatoms

Advanced Science, EarlyView.
Mesoporous mixed ionic‐electronic PU/PEDOT: PSS electrodes enable label‐free detection of stochastic extracellular bioelectrical dynamics in living Phaeodactylum tricornutum. Living diatoms actively modulate interfacial ionic dynamics, establishing stochastic electrochemical noise as a sensitive probe of microbial bioelectrochemical activity and a new ...

Motor Evoked Potentials Improve Targeting in Deep Brain Stimulation Surgery

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives One of the main challenges posed by the surgical deep brain stimulation (DBS) procedure is the successful targeting of the structures of interest and avoidance of side effects, especially in asleep surgery. Here, intraoperative motor evoked potentials (MEPs) might serve as tool to identify the pyramidal tract.

Machine‐Learning‐Assisted Impedance Component Analysis Enables Standardizable Surface Protein Analysis of Extracellular Vesicles Using Engineered Nanovesicles

Advanced Science, EarlyView.
This study establishes a universally applicable framework for vesicle surface analysis by combining engineered amyloid‐β‐displaying nanovesicles with machine‐learning‐optimized impedance spectroscopy. Equivalent‐circuit modeling reveals that membrane capacitance correlates with the surface protein states, enabling label‐free quantification of vesicle ...

Directional Deep Brain Stimulation for Parkinson's Disease: Results of an International Crossover Study With Randomized, Double‐Blind Primary Endpoint

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objective Published reports on directional deep brain stimulation (DBS) have been limited to small, single‐center investigations. Therapeutic window (TW) is used to describe the range of stimulation amplitudes achieving symptom relief without side effects.
