Drug Testing and Analysis, EarlyView.Micro‐QuEChERS sample preparation coupled to LC‐QQQ‐MS enabled sensitive quantification of nitazene analogs in 100 μL of plasma. The validated method provided low detection limits and was successfully applied to an authentic intoxication case involving N‐pyrrolidino protonitazene, supporting clinical and forensic toxicology workflows.

Drug Testing and Analysis, EarlyView.A validated LC‐HRMS/MS method enabled the first quantitative determination of the LGD‐4033 long‐term metabolite (M5‐b) in urine following controlled micro‐dose administration. The generated urinary reference data support the interpretation of adverse analytical findings and anti‐doping result management. ABSTRACT Selective androgen receptor modulators (

Drug Testing and Analysis, EarlyView.Nitazenes are increasingly present in the illicit drug supply, complicating harm reduction efforts. We have developed a rapid, nontargeted precursor ion scan method to detect emerging nitazenes in real‐world opioid samples. The method identified multiple nitazenes, often replacing pharmaceutical opioids or mixed with fentanyl and benzodiazepines ...

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 ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.In this study, a series of highly permeable CeO2 porous hollow microspheres with multilevel gas channels and tunable pore sizes were first prepared via the hydrothermal method, achieving rapid response and fast recovery to ammonia gas. Fast response and recovery performance is highly significant for real‐time monitoring of NH3 gas due to the toxic and ...

Optical methods (light or electron microscopy) are, in most cases, the basis for measuring the asbestos concentration either in air or in materials. The individual methods are described in a variety of guidelines or standards. The definition of terms like detection limit and analytical sensitivity have led to numerous discussions, driven by the fact ...

Average of normals (AON) is a quality control procedure that is sensitive only to systematic errors that can occur in an analytical process in which patient test results are used. The aim of this study was to develop an alternative model in order to apply the AON quality control procedure to datasets that include qualitative values below limit of ...
