AI Article Synopsis
- - Excessive fluoride in food and drinking water poses health risks, prompting the development of a new fluorescent probe (P-1) for detecting fluoride and other substances.
- - The probe first detects tert-butyldiphenylsilyl chloride (TBDS), leading to a reaction that creates a new sensor (P-2), which quantifies fluoride levels and measures viscosity.
- - Advanced characterizations and experiments confirm the sensors' effectiveness, enabling applications in healthcare and environmental monitoring, including the analysis of cells and various samples for fluoride presence.
Article Abstract
Excessive fluoride ions (F) in drinking water and food is harmful for human health and the environment. Therefore, a fluorescent probe tetraphenylethylene-quinoline (P-1) is developed with multiple sensing properties for the sequential detection of tert-butyldiphenylsilyl chloride (TBDS), F, and viscosity. Sensor P-1 first recognized TBDS and then observed an intramolecular charge transfer process, which produced an intermediate sensor P-2 in addition to fluorescence quenching at 576 nm. Following this, P-2 revealed a concentration-related quantitative analysis by tracking F and reproducing sensor P-1 reversibly with the fluorescence amplification at 496 nm when the SiN bond of P-2 was broken. A comparable sensing mechanism was noted in monitoring F and viscosity through a synthetically developed P-2 sensor. The characterizations (nuclear magnetic resonance-NMR, high resolution-mass-HR-MS, and high-performance liquid chromatography-HPLC) and density functional theory (DFT) confirmed the sensing mechanism of sensors P-1 and P-2. The proposed method was used to measure the viscosity of living cells and to measure F in food, water, and living cell samples. According to research results, quantitative emission characteristics versus F can offer insights into designing effective molecular probes with beneficial applications in healthcare and the environment.

Background: Nocturnal disturbances are a common symptom experienced by People Living with Dementia (PLWD), and these often present prior to diagnosis. Whilst sleep anomalies have been frequently reported, most studies have been conducted in lab environments, which are expensive, invasive and not natural sleeping environments. In this study, we investigate the use of in-home nocturnal monitoring technologies, which enable passive data collection, at low cost, in real-world environments, and without requiring a change in routine.

Soil analyses are essential to ensure economically and environmentally sustainable crop production while maintaining the soil fertile for future use. Unfortunately, common soil analyses may be highly demanding in terms of time, chemicals, and costs. This applies, in particular, when total quantities of elements are desired.

Healthcare researchers are increasingly utilizing smartphone sensor data as a scalable and cost-effective approach to studying individualized health-related behaviors in real-world settings. However, to develop reliable and robust digital behavioral signatures that may help in the early prediction of the individualized disease trajectory and future prognosis, there is a critical need to quantify the potential variability that may be present in the underlying sensor data due to variations in the smartphone hardware and software used by large population. Using sensor data collected in real-world settings from 3000 participants' smartphones for up to 84 days, we compared differences in the completeness, correctness, and consistency of the three most common smartphone sensors-the accelerometer, gyroscope, and GPS- within and across Android and iOS devices.
