Autonomous Reconfigurable Modular Conductive Hydrogels for Adaptive and Degradable Bioelectronic Interfaces

Advanced Materials Technologies, EarlyView.
Bridging rigid electrodes with soft, irregular tissues demands more than conductivity alone. Modular conductive hydrogels autonomously reconfigure into conformal electrode‐tissue interfaces, coupling mixed ionic‐electronic conduction with tissue‐like mechanics, self‐healing, and degradability.

Square-wave cathodic adsorptive stripping voltammetry of risperidone

Collection of Czechoslovak Chemical Communications, 2011
Electrochemical properties and diffusion-adsorption behavior of risperidone (RPN), an antiphyscotic drug, on hanging mercury drop electrode (HMDE) were carried out in Britton–Robinson (BR) buffer. Some electrochemical parameters such as diffusion coefficient, number of transferred electrons and proton participated to its reduction mechanism and surface

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

Determination of Nifuroxazide in Human Serum by Adsorptive Stripping Voltammetry

Analytical Sciences, 1999
The adsorption behavior of nifuroxazide on a hanging mercury drop electrode (HMDE) was critically examined using cyclic voltammetry and differential pulse techniques. The effect of different parameters on the accumulation behavior of the adsorbed species was tested. Thus, a sensitive stripping voltammetry procedure for the determination of nifuroxazide

Toward Prostate Cancer Early Warning with a Self‐Powered Wearable Biosensing Platform Integrated with Machine Learning

Advanced Science, EarlyView.
ABSTRACT Current prostate cancer detection methods remain limited in non‐invasiveness and specificity, prompting interest in urinary biomarkers such as sarcosine. Here, we report a urine‐powered wearable platform for non‐invasive sarcosine detection as a proof‐of‐concept for decentralized early warning.

Adsorptive stripping voltammetry of vitamin B12.

BUNSEKI KAGAKU, 1994
Vitamin B12 yields a polarographic catalytic wave at ca.-1.6 V vs. SCE. Vitamin B12 in river-water samples was determined by adsorptive stripping voltammetry in order to use this catalytic wave. The supporting electrolyte used was 0.01 M Na2HPO4+0.01 M NaH2PO4. A preconcentration potential of -1.2 V was applied for 5 min.
