Enzyme-based biosensing devices have been extensively developed over the last few
decades, and have proven to be innovative techniques in the qualitative and quantitative …

This review presents the principles of conductometric measurements in ionic media and the
equivalent electrical circuits of different designs for conductometric measurements. These …

The amino derivative of the UiO-66 metal organic framework (MOF) was investigated for
potential use as a sensing probe for formaldehyde (FA) in an aqueous medium. The …

We report the development of transparent sol–gels with entrapped sensitive and selective
reagents for the detection of formaldehyde. The sampling method is based on the adsorption …

A novel formaldehyde sensor based on nanofibrous polyethyleneimine (PEI)/bacterial
cellulose (BC) membranes coated quartz crystal microbalance (QCM) has been successfully …

Several electrochemical biosensors based on various enzyme inhibition effects have been
designed; their laboratory prototypes have been manufactured and thoroughly investigated …

A new immunoassay concept for the determination of aflatoxin B1 (AFB1) based bio-
electrocatalytic reaction on micro-comb electrode was proposed. The micro-comb electrode …

Formaldehyde, the simplest molecule of the aldehyde group, is a gaseous compound at
room temperature and pressure, is colorless, and has a strong, pungent odor. It is soluble in …

A rapid and sensitive cataluminescence (CTL)-based gas sensor using nanosized
V2Ti4O13 as a probe was proposed for the determination of formaldehyde in air. The gas …

Toxicants in water sources are of concern. We developed a tool that is affordable and easy-
to-use for monitoring toxicity in water. It is a biosensor composed of disposable bioreporter …
