The recent increase in cardiovascular and metabolic disease in the Navajo population residing close to the Grants Mining District (GMD) in New Mexico is suggested to be due to exposure to environmental contaminants, in particular uranium in respirable dusts. However, the chemistry of uranium-containing-dust dissolution in lung fluids and the role of mineralogy are poorly understood, as is their impact on toxic effects. The current study is focused on the dissolution of xcontaining-dust, collected from several sites near Jackpile and St. Anthony mines in the GMD, in two simulated lung fluids (SLFs): Gamble's solution (GS) and Artificial Lysosomal Fluid (ALF). We observe that the respirable dust includes uranium minerals that yield the uranyl cation, UO 2 2+ , as the primary dissolved species in these fluids. Dust rich in uraninite and carnotite is more soluble in GS, which mimics interstitial conditions of the lungs. In contrast, dust with low uraninite and high kaolinite is more soluble in ALF, which simulates the alveolar macrophage environment during phagocytosis. Moreover, geochemical modeling, performed using PHREEQC, is in good agreement with our experimental results. Thus, the current study highlights the importance of site-*

“…) is one of the most common radioactive pollutants in the environment, and the concerns about its environmental effects and threats to human health have steadily increased over time [1][2][3][4]. Hence, there is an urgent need to precisely and rapidly monitor the content of uranyl ions in environmental aqueous settings, which has resulted in the rapid development of many different uranyl detection methods, such as colorimetric methods [5][6][7], fluorescence methods [8,9], mass spectrometry [10][11][12], and electrochemistry [13,14]. Due to its fast response, high sensitivity, and its successful application in the rapid trace analysis of biological molecules [15][16][17], organic pollutants [18][19][20][21][22], and heavy metal ions [23,24], SERS is expected to become an alternative technique for the detection of uranyl.…”

“…Bio-based fluorescence probes of Cur-cysteine and Cur-tryptophan (Figure - 31c ) demonstrated the capability for picric acid detection in aqueous solutions based on the aggregation-induced emission effect . The enhanced fluorescence intensity of Cur (Figure - 31d ) in the presence of Triton X-100 was quenched by UO 2 2+ ions in water samples along with a color change from bright yellow to orange …”

“…111 The enhanced fluorescence intensity of Cur (Figure 12-31d) in the presence of Triton X-100 was quenched by UO 2 2+ ions in water samples along with a color change from bright yellow to orange. 112 A dual fluorescence and electrochemical platform based on the Cur (Figure 12-31e,f)-graphene quantum dots (Cur-GQDs) coated on the transparent indium−tin oxide electrode (Cur-GQDs-ITO) was developed for the sensitive monitoring of apolipoprotein E4 DNA (Apo E4 DNA), which is responsible for Alzheimer's disease. The increase of the biomarker concentration results in a decrease of both amperometric and fluorescence signals.…”

Because of numerous inherent and unique characteristics of phytochemicals as bioactive compounds derived from plants, they have been widely used as one of the most interesting nature-based compounds in a myriad of fields. Moreover, a wide variety of phytochemicals offer a plethora of fascinating optical and electrochemical features that pave the way toward their development as optical and electrochemical (bio)sensors for clinical/ health diagnostics, environmental monitoring, food quality control, and bioimaging. In the current review, we highlight how phytochemicals have been tailored and used for a wide variety of optical and electrochemical (bio)sensing and bioimaging applications, after classifying and introducing them according to their chemical structures. Finally, the current challenges and future directions/perspective on the optical and electrochemical (bio)sensing applications of phytochemicals are discussed with the goal of further expanding their potential applications in (bio)sensing technology. Regarding the advantageous features of phytochemicals as highly promising and potential biomaterials, we envisage that many of the existing chemical-based (bio)sensors will be replaced by phytochemical-based ones in the near future.
