Isolation of biofluids from tissues using a vacuum-assisted filtration biomedical device

Area of Science:

• Biomedical Engineering
• Biochemistry
• Histology

Background:

• Interstitial fluid (IF) is crucial for tissue health but often co-collected with tissue during biopsies.
• Current methods lack the ability to isolate IF from tissue for separate molecular characterization.
• Distinguishing between tissue-specific and IF-specific molecules is vital for accurate diagnostics.

Purpose of the Study:

• To design and validate a biomedical device for efficient separation of interstitial fluid from tissue samples.
• To enable separate molecular analysis of tissue and interstitial fluid.
• To improve the accuracy of molecular diagnostics derived from tissue biopsies.

Main Methods:

• Development of a novel biomedical device utilizing vacuum-assisted filtration.
• Tissue samples were subjected to filtration, collecting extracted fluid in a dedicated chamber.
• Characterization of tissue weight changes and glycan profiles before and after filtration.

Main Results:

• The device successfully separated interstitial fluid from tissue samples.
• Vacuum-assisted filtration demonstrated significant removal of interstitial fluid.
• Analysis confirmed the device facilitates the study of tissue-specific molecules while minimizing IF contamination.

Conclusions:

• The developed biomedical device effectively separates interstitial fluid from tissue.
• This separation allows for enhanced molecular characterization of tissue-specific components.
• The device holds potential for improving diagnostic accuracy in various biomedical applications.
