Sensors and regulators of intracellular pH
Nature Reviews Molecular Cell Biology, 2009Protons dictate the charge and structure of macromolecules and are used as energy currency by eukaryotic cells. The unique function of individual organelles therefore depends on the establishment and stringent maintenance of a distinct pH. This, in turn, requires a means to sense the prevailing pH and to respond to deviations from the norm with ...

Animals can survive only within a narrow pH range. This requires continual monitoring of environmental and body‐fluid pH. Although a variety of acidic pH sensor molecules have been reported, alkaline pH sensor function is not well understood. This Review describes neuronal alkaline pH sensors, grouped according to whether they monitor extracellular or ...

A differential ISFET pH sensor
2017 IEEE SENSORS, 2017In this paper, we present a simple differential CMOS ISFET based pH sensor. The design uses two different sensing areas. The resulting sensor reduces complexity and power consumption making it suitable for implantable biomedical applications. The design is implemented in a standard 130nm process and the design constraints on sensitivity are explored ...

Dynamic photonic structures can be modulated by changing the periodic structure and/or the index of refraction. These dynamic photonic structures allow responsive capability for sensing external stimuli to control the properties of light and act as optical transducers.
