Recent progress in the development of organic small-molecule and functional material fluorescent probes for formaldehyde detection and imaging

Proposals for gas-detection improvement of the FeMPc monolayer towards ethylene and formaldehyde by using bimetallic synergy

“…These single-atom-layer structured materials showcase high surface area, excellent electrical properties and surface reactivity, offering substantial advantages in gas-sensing applications. 24–26 There are various types of sensors, including biosensors, optical sensors, gas sensors and fluorescence sensors, 27,28 each featuring unique sensing mechanisms and applications. Biosensors and optical sensors possess the ability to detect targets by monitoring changes in the refractive index or utilizing the photonic spin Hall effect, 29–31 offering advantages such as stability, high precision, and exceptional sensitivity.…”

Solution and gaseous phase sensing of formaldehyde with economical triphenylmethane based sensors: a tool to estimate formaldehyde content in stored fish samples

“…The limit of detection (LOD) of the deprotonated form (sensor 2 ) for FA was superior to the majority of FA sensors reported so far (Table S1†). 38,39 The LOD (limit of detection) value also suggests that trace amounts of FA may be detected with the help of sensor 2 . Moreover, the sensor was effectively immobilized into a starch–PVA polymer matrix which enabled detection of FA in a 100% aqueous system.…”

Recent Advances in Electrochemical Sensors for Formaldehyde

“…However, spectroscopic methods often require the use of derivatization or fluorescent probe molecules, necessitating the specific design and synthesis of responsive molecules. Comprehensive reviews have been conducted to provide an overview of the relevant research on these methods [ 14 , 44 , 45 , 46 , 47 , 48 , 49 ].…”
