Potentiometric Sensor for Nonionic Surfactants

open access: yes, 2023
Nonionic surfactants are composed of molecules that lack a charged functional group, unlike their anionic (negatively charged) and cationic (positively charged) counterparts. They are typically formed by combining hydrophilic groups like polyethylene glycol, ethoxylated sorbitan, or ethoxylated fatty alcohols with hydrophobic groups such as long alkyl ...

A New Kinetic‐Mechanistic Approach Towards Spectrophotometric Bioanalysis of 2‐Phenylethylamine as a Sympathomimetic Agent Using Sodium Isopropyl Xanthate

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT 2‐Phenylethylamine (2‐PEA), an aromatic biogenic amine, demonstrates significant physiological and toxicological effects on human health. A variety of conventional methods have been widely used for the determination of 2‐PEA. However, the necessity of complex sample preparation and high cost of instrumentation may pose challenges to their ...

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells

open access: yesMolecular Oncology, Volume 20, Issue 5, Page 1202-1219, May 2026.
We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox

Online monitoring of yeast cultivation using a fuel-cell-type activity sensor [PDF]

open access: yes, 2018
A microbial fuel-cell type activity sensor integrated into 500mL and 3.2L bioreactors was employed for ampero- (μA) and potentiometric (mV) measurements.

Prenucleation Species Dictate Foreign Ion Incorporation in the Biomineral Precursor Amorphous Calcium Carbonate

open access: yesAdvanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
ACC forms via aggregating prenucleation clusters that gatekeep its chemical composition. Ion identity steers the path: Ba and Sr substitute Ca in clusters, thereby inhibiting nucleation, with a dose‐dependent switch of Sr to induction. Mg partitions into Mg‐rich and Mg‐poor clusters; the latter form ACC, expelling Mg.

Selection of Anode Half‐Cells for Hydrogen Peroxide Self‐Powered Electrochemical Sensors Using Biomimetic Metal Complex Cathode Catalysts

open access: yesAnalysis &Sensing, Volume 6, Issue 3, May 2026.
The work provides novel insights into the operation mechanism of the self‐powered electrochemical sensors for the determination of hydrogen peroxide. The role of chloride anions in a supporting electrolyte, and reactions at the anode which contribute to the operation mechanism of the sensors, have been highlighted.
