Investigation of Metformin Contamination in Horses: Implications for Environmental Exposure and Doping Control

Drug Testing and Analysis, EarlyView.
The widespread use of metformin in human medicine coupled with the detection of metformin in blood and urine samples collected from racehorses has raised concern about the potential for exposure from contaminated stalls. This study describes blood and urine concentrations in horses following intentional exposure of horses to metformin contaminated ...

Exploring Cerumen as an Alternative Matrix for Drug Detection and Quantification: Method Development and Application in Clinical Samples

Drug Testing and Analysis, EarlyView.
An LC–MS/MS method was developed for the detection of 33 psychoactive medications in cerumen (earwax) and applied to the samples of 60 psychiatric inpatient volunteers. The findings highlighted the utility of cerumen as an innovative biospecimen in clinical toxicological analysis.

Machine Learning–Enhanced Fluorescence Cryptography with NADH‐Responsive Polymer Dots

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study presents a smart anticounterfeiting system using semiconducting polymer dots (Pdots) that exhibit tunable fluorescence responses to NADH. By integrating these dynamic optical signals with machine learning–based decoding, the work establishes a secure and intelligent encryption platform, showing a novel strategy that links chemical sensing ...

Validated RP‐HPLC–UV Method for the Quantitative Analysis and Stability Evaluation of Amoxicillin in Paediatric Gummy Tablets

ELECTROPHORESIS, EarlyView.
A validated RP‐HPLC–UV method was successfully applied for amoxicillin determination in gummy tablets. The method is useful for an accurate amoxicillin content determination in paediatric gummies and was applied to study the stability profile of the drug, evaluated over 6 months under storage conditions.
