In this paper, we review recent research articles on liquid-phase microextraction of drug
substances from biological fluids, such as plasma, serum, urine, and saliva. We focus on papers …

Background: Oral fluid is an alternative matrix with potential applications in road-side drug
screening, work-place testing, drug treatment programs, and epidemiological surveys. …

Oral fluid has become an important matrix for drugs of abuse analysis. These days the
applicability is challenged by the fact that an increasing number of new psychoactive drugs are …

A method for the simultaneous determination of the beta-blockers atenolol, sotalol,
metoprolol, bisoprolol, propranolol and carvedilol, the calcium-channel antagonists diltiazem, …

An ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS-MS)
method for screening of drugs in whole blood has been developed and validated. Samples …

The relationship of drug concentrations between oral fluid and whole blood was evaluated
by studying the linear correlation of concentrations and calculating the oral fluid to blood …

In this work, we investigated for the first time hydrophobic deep eutectic solvents (DES) as
supported liquid membrane (SLM) for electromembrane extraction (EME). Camphor, coumarin…

During a 6 month period (July 2010–January 2011) we observed 12 fatal intoxications and
22 non-fatal cases related to the drug paramethoxymethamphetamine (PMMA) in Norway (…

For the first time, electromembrane extraction (EME) of six basic drugs of abuse from undiluted
whole blood and post mortem blood in a totally stagnant system is reported. Cathinone, …

The repeatability and extraction recoveries of parallel electromembrane extraction (Pa-EME)
was thoroughly investigated in the present project. Amitriptyline, fluoxetine, and haloperidol …
