Advances in sensor materials and optoelectronics have enabled novel optical sensors for applications in life sciences, pharmaceuticals, biotechnology, and more. Compared with electrochemical sensing ...

Background and Aims: The tests that are currently available for the diagnosis of gastroesophageal reflux disease (GERD) lack the desired diagnostic accuracy. To date, only pH monitoring has been shown ...

Sweat, which contains a wide range of biochemical markers, can tell us a lot about our health. Variations in sweat pH (i.e. acidity or alkalinity), for instance, can tell us whether our body is ...

(Nanowerk Spotlight) Inside a wound, a complex chemical battle unfolds. As healing progresses, the wound environment shifts between acidic and basic states, each change signaling different stages of ...

Given the pivotal role pH plays in many aspects of food production, choosing the right pH electrode and meter is an important ...

In a recent study published in Scientific Advances, researchers created a bioresorbable, cordless, passive sensor that monitors pH locally and detects stomach leakage early on. Study: Bioresorbable, ...

The circuit shown in Figure 1 is a completely isolated low power pH sensor signal conditioner and digitizer with automatic temperature compensation for high accuracy. The circuit gives 0.5% accurate ...

To ensure accuracy, we had our garden soil’s pH levels professionally lab tested. We then used each pH meter and compared its results with the lab readings. We also evaluated for ease of use, value, ...

The incidence of GERD is on the rise, particularly in Asia. [24] Along with the increasing incidence of this disease, newer endoscopic and laparoscopic surgical techniques are also emerging for its ...
