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

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 ...

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 ...

The current standard method for detection of gastroesophageal reflux (GER) in infants and children is pH monitoring (pH probe). The addition of impedance probe measurements may or may not increase the ...

Ambulatory 24 h esophageal pH monitoring enables quantification of esophageal acid exposure and assessment of the temporal relationship between symptoms and acid reflux events. Analysis of pH ...
