Question

What are the advantages of microfabricated ISEs? Describe typical applications of this type of sensor.

Short answer

A little amount of analyte is required for microfabricated ISEs. They are typically used in the investigation of the cell's morphology.

Step-by-step solution

Concept introduction

Membrane Indicator Electrodes or Ion Selective Electrodes (ISEs) are used to monitor the $pH$of a solution and are made up of a thin glass membrane. Only the intended ions can pass across the membrane. The transportation of ions from a higher concentration to a lower concentration via the membrane creates a potential difference near the membrane.

Advantages

• They are very small in size.
• A very small amount of solution is needed for them to operate.
• They have selective reactivity with the analyte.

Applications

• Drug analysis
• Study of cellular level
• Biosensors
• Environment monitoring
