“…The modern extraction technique QuEChERS has been used to validate the reliability of the elaborated sensor for DNOC determination in potatoes. 41 Two beakers each containing 10 grams of chopped potato were doped with 5 mL of 0 and 0.5 μM DNOC solution and homogenized for 15 minutes. Then 5 mL of acetate buffer was added to each container and shaken in a vortex shaker vigorously for 10 minutes.…”

The development of an analytical methodology commonly includes sampling and sample pretreatment-preparation. The sample preparation step should provide the analytes (pesticides, heavy metals, drugs, dyes…etc.) in an adequate medium (typically aqueous or non-aqueous solution) to be detected and/or quantified. It is, therefore, necessary to ensure that the sample is homogeneous and free of interferents, as long as the preparation step is the most significant source of error in the analytical method development and is the most time-consuming step especially when solid samples are analyzed. Given its importance, this preparation step has a fundamental importance in the overall analytical method development, mainly when electroanalytical methods are applied. In this chapter, the steps involved in preparing samples for electrochemical analysis will be described in detail. Specifically, we will be focusing on the sample preparation techniques for the electrochemical analysis of pesticides and heavy metals, in environmental and food samples. For non-electrochemical readers, a brief introduction to the most commonly used electroanalytical methods will be described.

For the sensitive and convenient detection of acute liver injury, several methods and materials have been developed. However, it is still a challenge to obtain sensitive, simple detection techniques for acute liver injury. Here, based on a gold nanoflowers (GNFs) modified substrate and 6-mercaptopurine (6-MP) as a surface-enhanced Raman scattering (SERS) signal molecule, a novel method was developed for monitoring carbon tetrachloride (CCl 4 )-induced acute liver injury of mice. Glutathione (GSH)-triggered and glutathione-s-transferase (GST)-accelerated the turn-off SERS behavior of 6-MP was studied on the GNFs substrate. We found that GSH-triggered GST-accelerated turn-off behavior of 6-MP on the GNFs substrate surface in buffer systems. In CCl 4 -induced acute liver injury mice tissue extracts without adding GST, the turn-off behavior of 6-MP was also accelerated, the detection intensity from 10 5 down to 10 3 counts for 6-MP. The SERS results confirmed that GNFs substrate exhibited strong SERS signal intensity, excellent stability in complex biological environment and detection clinical sample. This study provides a new, rapid and sensitive approach for analysis of trace amounts detection based on SERS coupled with GNFs substrate, which has great potential for analysis of surface chemical properties indicating its potential applicability in biological and biomedical research.
