- Biomedical Engineering
Background:
- Drug development for brain diseases requires understanding drug behavior at the site of action.
- Directly sampling from the brain's interstitial space is technically difficult.
- Limited techniques exist for monitoring macromolecules in the brain.
Purpose of the Study:
- To review the applicability of microdialysis, cerebral open flow microperfusion, and electrochemical biosensors for macromolecule monitoring in the brain.
- To discuss innovations, challenges, and research gaps in these brain-sampling techniques.
- To highlight the potential of these methods in advancing brain-targeted drug development.
Main Methods:
- Review of existing literature on microdialysis, cerebral open flow microperfusion, and electrochemical biosensors.
- Analysis of the capabilities of these techniques for in vivo brain sampling and local drug delivery.
- Discussion of technical aspects, limitations, and future research directions.
Main Results:
- Microdialysis and cerebral open flow microperfusion enable direct sampling and local application of molecules in the brain.
- Electrochemical biosensors offer an alternative for macromolecule monitoring.
- These techniques provide crucial pharmacokinetic and pharmacodynamic insights for brain-targeted therapies.
Conclusions:
- Microdialysis and cerebral open flow microperfusion are valuable tools for studying brain drug delivery.
