Development of a nalmefene formulation suitable for a community‐use auto‐injector

British Journal of Clinical Pharmacology, EarlyView.
Aim Time to onset of reversal is critical when treating opioid‐induced respiratory depression and hypoxia. This study aimed to develop a formulation of the opioid antagonist nalmefene with an increased absorption rate and reduced time to onset of reversal following intramuscular administration. Methods Several absorption enhancers were screened in rats,

A Laser-Based Method for the Detection of Honey Adulteration

Applied Sciences, 2021
In the present work, laser-induced breakdown spectroscopy, aided by some machine learning algorithms (i.e., linear discriminant analysis (LDA) and extremely randomized trees (ERT)), is used for the detection of honey adulteration with glucose syrup.

BODIPY‐based J‐aggregates: From supramolecular chemistry to NIR bioimaging and phototherapies

Bulletin of the Korean Chemical Society, EarlyView.
BODIPY dyes form ordered J‐aggregates through controlled supramolecular self‐assembly, producing narrow, red‐shifted absorption bands with small Stokes shifts. This review highlights design strategies governing J‐aggregation, structure–property relationships, and applications in sensing, bioimaging, and phototherapy, guiding functional BODIPY‐based ...

Inclusion Complexations of Levamisole and Cocaine With Molecular Baskets. Fluorescence Displacement Assay for Detection of Cocaine and Its Adulterant Levamisole in Aqueous Media

Chemistry – A European Journal, EarlyView.
Levamisole is a common adulterant found in street‐distributed cocaine. Molecular baskets have been shown to form stable inclusion complexes with both substances. While levamisole inserts its benzene into the basket's cavity, cocaine utilizes its bicyclic ring for encapsulation.
