Capillary electrophoresis and microdialysis: current technology and applications

Area of Science:

• Analytical Chemistry
• Biomedical Engineering
• Pharmacology

Background:

• Microdialysis sampling enables continuous in vivo monitoring of endogenous and exogenous substances.
• Traditional analysis of microdialysis samples relies on liquid chromatography (LC).
• LC methods require large injection volumes, leading to extended sampling times.

Purpose of the Study:

• To review technologies for capillary electrophoresis (CE).
• To highlight CE's application in analyzing microdialysis samples.
• To present CE as an alternative to LC for microdialysis analysis.

Main Methods:

• Review of current capillary electrophoresis (CE) technologies.
• Examination of CE's application in microdialysis sample analysis.
• Comparison of CE with traditional LC methods for microdialysis.

Main Results:

• Capillary electrophoresis (CE) offers high resolution and requires minimal sample volumes.
• CE significantly reduces microdialysis sampling times compared to LC.
• Various CE technologies are effective for analyzing diverse molecules in microdialysis samples.

Conclusions:

• Capillary electrophoresis (CE) is a powerful and efficient alternative to LC for microdialysis sample analysis.
• The small sample volume and high resolving power of CE make it ideal for in vivo monitoring.
• CE technologies are well-suited for quantifying neurotransmitters and drug substances from microdialysis.
