Beyond Total Content: Assessing the Bioaccessibility of Metals in Tattoo Inks Using Validated Extraction Media

Analytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT A validated analytical workflow is presented for determining total and bioaccessible concentrations of regulated elements in tattoo inks, addressing the lack of harmonized protocols for comparing extraction approaches in complex matrices. Although current legislation defines limits for soluble fractions of selected metals, it does not specify ...

Development and Validation of Two Analytical Methods Using High‐Performance Liquid Chromatography and Atomic Absorption Spectroscopy for the Analysis of Tunisian Marketed Pharmaceutical Product‐Based Insulin and Zinc: Application in Routine Stability Study

Biomedical Chromatography, Volume 40, Issue 11, November 2026.
ABSTRACT Given the widespread reliance on insulin among diabetic patients, ensuring its stability is an essential task not only for preserving its therapeutic efficacy but also for safeguarding patient health and safety. In addition, insulin storage practices were frequently misunderstood that may compromise drug potency.

Experimental methods in chemical engineering: Cyclic voltammetry—CV

The Canadian Journal of Chemical Engineering, Volume 104, Issue 11, Page 5776-5827, November 2026.
Abstract Cyclic voltammetry (CV) is a foundational electroanalytical technique for investigating redox behaviour and evaluating material performance across fields such as molecular electrochemistry, electrocatalysis, sensing, and energy storage. Despite its widespread use, a gap remains between formal electrochemical theory and the practical data ...

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

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
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 ...
