Accelerated Detection of Viral Particles by Combining AC Electric Field Effects and Micro-Raman Spectroscopy

Sensors, 2015
A detection method that combines electric field-assisted virus capture on antibody-decorated surfaces with the “fingerprinting” capabilities of micro-Raman spectroscopy is demonstrated for the case of M13 virus in water.

Lactate Homeostasis Disruption Potentiates TACE‐Immunotherapy in Hepatocellular Carcinoma

Advanced Science, EarlyView.
Lactate homeostasis is disrupted through spatially coordinated extracellular neutralization and intracellular acidification, triggering calcium overload, mitochondrial dysfunction, and immunogenic cell death. This metabolic reprogramming alleviates the immunosuppressive tumor microenvironment and enhances immune checkpoint blockade, providing a ...

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.

Batch-fabricated full glassy carbon fibers for real-time tonic and phasic dopamine detection

Frontiers in Bioengineering and Biotechnology
Dopamine (DA) is a critical neurotransmitter that is key in regulating motor functions, motivation, and reward-related behavior. Measuring both tonic (baseline, steady-state) and phasic (rapid, burst-like) DA release is essential for elucidating the ...

Cost‐Effective Ti/Al/Ni Multilayer Neural Probes With In Vivo Recording Performance Comparable to Ti/Au Neural Probes

Advanced Electronic Materials, EarlyView.
In this study, we developed a cost‐efficient neural probe by replacing traditional gold with an aluminum‐based Ti/Al/Ni multilayer stack. Optimizing this metal architecture suppressed oxidation and ensured robust electrical stability, achieving signal quality comparable to standard gold probes. It enables a highly accessible and economical solution for

The reactivity of platinum microelectrodes

Physical Chemistry Chemical Physics, 2016
Platinum ultramicroelectrodes exhibit lower reactivity towards surface sensitive reactions than macroelectrodes, typically due to (trace) contamination, making electrochemical characterization very important for a proper comparison.
