“…The presence of water content in organic solvents can give rise to several challenges and complexities, including diminished solvent performance, phase separation, potential product degradation, and the risk of lowered flash points and increased volatility. Hong et al [42] utilized the benzothiazole group, which is commonly used in fluorescencebased chemosensors, to create a new fluorescence probe for detecting water content. They presented a dithiophene-bearing benzothiazole derivative (DTBz) that is responsive to moisture, with the addition of a hydroxyl group to facilitate the establishment of hydrogen bonds with water molecules.…”

Traditionally, analytical chemistry and diagnosis relied on wet laboratories and skilled professionals utilizing sophisticated instruments for sample handling and analysis. However, with the development of novel materials and sensing techniques, there has been a significant shift towards the use of standalone sensors, allowing tests to be conducted on-site or even in real time, leading to cost- and time-efficiency. With their widespread adoption globally, smartphones have emerged as an ideal platform for such sensors, boasting extensive sensor capabilities, advanced processing power, and communication functionalities. Smartphone-based assays make use of optical and electrochemical sensors, utilizing built-in cameras, ambient light sensors, and other features for optical sensing, while the micro-USB port, Bluetooth, and wireless connection facilitate data transmission and analog voltage application for electrochemical sensing. Previous overview papers have explored smartphone-based sensing in specific domains; this review provides a comprehensive examination of recent advancements in smartphone-based sensors, encompassing both optical and electrochemical sensing methods. The review provides the fundamental principles of these sensors and their implementation using smartphones, showcases recent applications, and presents innovative designs that take advantage of the inherent functionalities and sensor capabilities of smartphones. The review concludes by offering an outlook on the prospects of smartphone-based sensing and includes a reflective section emphasizing the potential impact of sensors in chemical and biological analyses. This comprehensive resource aims to provide information to researchers and practitioners interested in using smartphones for cutting-edge analytical methodologies.

“…In recent years, there has been increasing interest in the development of fluorescent sensors and their functional materials, including polymers, membranes, and sensor-immobilized substrates for detecting and visualizing water in solids, solutions, and gas or on material surfaces, because such fluorescent sensing systems for water are crucial to environmental and quality control monitoring, industrial processes, food inspection and so on. 1–24 Actually, some kinds of organic fluorescent sensors for water, based on ICT (intramolecular charge transfer), 25–33 ESIPT (excited state intramolecular proton transfer), 34–37 PET (photo-induced electron transfer), 38–52 or solvatochromism have been developed which exhibit photophysical changes in wavelength, intensity, and lifetime of fluorescence emission depending on the water content. Hence, over the last decade and a half, we continued to make much effort to design and develop PET-type fluorescent sensors for water in solvents.…”
