The analysis of controlled drugs in forensic matrices, ie, urine, blood, plasma, saliva, and
hair, is one of the current hot topics in the clinical and toxicological context. The use of …

Direct analysis of samples, regardless their origin, is desirable although for the majority of
cases unfeasible on account of the complexity of the sample matrix, inadequate …

An ionic liquid-based ultrasonic-assisted extraction method has been successfully applied to
the effective extraction of phenolic compounds from Laminaria japonica Aresch. Three kinds …

Abstract 3D graphene-carbon nanotubes (G-CNTs) composite with unique morphology and
structure was prepared by one-step insertion of CNTs into graphene. Subsequently, the G …

Halogen-based polymeric ionic liquid (PIL) fibers, which have proved efficient for solid-
phase microextraction (SPME) of polar compounds, were with very limited fiber lifetimes. In …

In this work, hybrid silica-based materials with immobilized ionic liquids (ILs) were prepared
by sol–gel technology and evaluated as solid-phase microextraction (SPME) fiber coatings …
