“…S4. A cloud point phenomenon will occur with the phase separation: the solution becomes cloudy due to the decrease of solubility of the surfactant when the external temperature changes (such as temperature), and then the two phases are separated and formed [95]. One important characteristic of the surfactants used in CPE extraction is that they tend to form micelles, that is, the hydrophobic part of each molecule of the surfactant polymerizes toward the inner center and forms a liquid core with other hydrophobic groups, thus forming a hydrophobic pseudophase at the center of the micelles.…”

A few advancing technologies for natural product analysis have been widely proposed, which focus on decreasing energy consumption and developing an environmentally sustainable manner. These green sample pretreatment and analysis methods following the green Analytical Chemistry (GAC) criteria have the advantage of improving the strategy of chemical analyses, promoting sustainable development to analytical laboratories, and reducing the negative effects of analysis experiments on the environment. A few minimized extraction methodologies have been proposed for replacing the traditional methods in the quality evaluation of natural products, mainly including solid‐phase microextraction (SPME) and liquid phase microextraction (LPME). These procedures not only have no need for large numbers of samples and toxic reagent, but also spend a small amount of extraction and analytical time. This overview aims to list out the main green strategies on the application of quality evaluation and control for natural products in the past 3 years.

“…Hence, a cheap, sensitive, selective, and environmentally friendly analytical methods and materials affordable for developing countries are of utmost importance to regularly monitor the amounts of these toxic metals in different matrices. Several methods have been developed to monitor toxic metals in various sample matrices such as atomic absorption spectroscopy [16,17], graphite furnace atomic absorption spectrometry [18,19], inductively coupled plasma-atomic emission spectrometry [20]. These methods are sensitive; however, they require laborious sample preparation, skilled personnel, and high operational costs, which make them not suitable for fieldwork analysis.…”

“…The need for cadmium detection has increased over the past few years, and the methods commonly used for cadmium detection are atomic absorption spectrometry (AAS) [10,11], atomic emission spectrometry (AES) [12,13], inductively coupled plasma mass spectrometry (ICPMS) [14,15], conductometric analysis (CA) [16,17], anodic stripping voltammetry (ASV) [18][19][20][21], immunoassays, and biosensors. AAS, AES, and ICPMS all require large-scale analysis equipment and complex operations.…”

In this work, ammonium pyrrolidine dithiocarbamate (APDC) was used as a surface etchant to modify CdTe/CdS core-shell quantum dots (QDs). The APDC etchant combines with the cadmium ions (Cd2+) on the surface of the QDs, resulting in the formation of surface holes. The formation of these holes changes the QD surface structure, which leads to fluorescence quenching of the QDs. Newly added Cd2+ can selectively recognize and combine with these holes; thus, the fluorescence intensity of the QDs can be restored. The linear response of this turn-on fluorescent sensor was found to be 0–100 μg/L and 100–600 μg/L under the determined optimal conditions, and its limit of detection (LOD) for Cd2+ was 2.642 μg/L (23.5 nmol/L).
