Paper-based sensors, often referred to as paper-based analytical devices (PADs), stand as
a transformative technology in the field of analytical chemistry. They offer an affordable …

Signal readout technologies that do not require any instrument are essential for improving
the convenience and availability of paper-based sensors. Thanks to the remarkable …

Using silver nanoparticles (AgNPs) and carboxymethyl cellulose (CMC), a simple distance-
based paper analytical device (dPAD) was developed for the determination of chloride ions …

In the context of global demand for carbon reduction, the formation of inorganic carbon (IC)
in the wastewater from oil flooding becomes a potential threat. In this study, Chlorella sp …

Abstract The Lucas-Washburn equation is commonly used to predict the distance (L) that a
liquid travels through paper. This equation establishes that L 2 is linear with time and …

Multimodal biosensors can reduce false negative/positive rates to produce more reliable
results. In this study, we report a multimodal biosensor that can achieve the detection of …

We present a temperature-compensated Fabry-Pérot interferometer (FPI) fiber-optic
bicarbonate concentration sensor based on the Vernier effect. The proposed sensor is …
