Clinical Laboratory Innovations: Nanoscale Detection of Chloramphenicol Using Nanomaterial Biosensors

Analytical Science Advances, Volume 7, Issue 2, December 2026.
Nanosensor schematic functionalized with specific bioreceptors that produce electrochemical signals upon Chloramphenicol binding. Resulting voltammetric readouts (differential pulse, square‐wave, and cyclic voltammetry) are analyzed to identify and quantify Chloramphenicol.

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 ...

Systematic Optimization of an SLE‐DAPTAD LC–MS/MS Workflow for Simultaneous Quantification of Low‐Abundance Vitamin D3 Metabolites in Plasma

Rapid Communications in Mass Spectrometry, Volume 40, Issue 20, 30 October 2026.
ABSTRACT Rationale Liquid chromatography–tandem mass spectrometry (LC–MS/MS) analysis of vitamin D3 metabolites is analytically challenging because these compounds are structurally similar, strongly matrix‐associated, and have poor ionization efficiency.
