Ionic liquid-based ultrasound-assisted dispersive liquid–liquid microextraction combined with electrothermal atomic absorption spectrometry for a sensitive determination of cadmium in water samples
TL;DR: In this article, a new method was developed for the determination of cadmium in water samples using ionic liquid-based ultrasound-assisted dispersive liquid-liquid microextraction (IL-based USA-DLLME) followed by electrothermal atomic absorption spectrometry (ETAAS).

Determination of Surface-Immobilized Double-Stranded DNA Using a Metallointercalator and Catalytic Voltammetry
TL;DR: In this article, a high-affinity intercalator, Ru(bpy)2(dppz)2+ (bpy = 2,2′-bipyridine, dppz = dipyrido[3,2-a:2′,3′-c]phenazine), as a redox indicator, and oxalate as a sacrificial electron donor in solution to chemically amplify the voltammetric signal of the indicator.

Multiple DNA binding modes of a metallointercalator revealed by DNA film voltammetry.
TL;DR: The appearance of two peaks in the voltammetric measurements of CT-DNA was rationalized by invoking two different DNA binding modes for the Ru-dppz complex: intercalation and electrostatic association.

Direct determination of Cd and Pb in gel forming konjac samples by enzymatic hydrolysis assisted slurry sampling graphite furnace atomic absorption spectrometry
TL;DR: In this paper, a method of sampling after an enzymatic hydrolysis pretreatment was developed for the determination of Cd and Pb in refined konjac flour, by graphite furnace atomic absorption spectrometry (GFAAS).
