Summary
New stochastic sensors accurately measure glycogen in tissue samples. These sensors are crucial for assessing tissue health and aging, offering high sensitivity for glycogen detection.
Area of Science:
- Biomedical Engineering
- Analytical Chemistry
- Biochemistry
Background:
- Glycogen screening in tissues is vital for understanding aging and health.
- Accurate glycogen quantification is essential for various diagnostic and research applications.
Purpose of the Study:
- To develop and characterize novel stochastic sensors for reliable glycogen analysis in tissue samples.
- To establish sensitive detection methods for glycogen relevant to tissue health assessment.
Main Methods:
- Design and fabrication of two needle stochastic sensors using maltodextrins (MD-m and MD-M) with varying dextrose equivalence (DE).
- Immobilization of maltodextrins in a diamond paste matrix composed of synthetic diamond and paraffin oil.
- Characterization of sensor performance for both qualitative and quantitative glycogen assays.
Main Results:
- Successfully developed and characterized two types of stochastic sensors (MD-m and MD-M).
- Demonstrated reliable qualitative and quantitative analysis of glycogen in tissue samples.
- Achieved a low limit of determination for glycogen assay, as low as 1 fmol L-1.
Conclusions:
- The developed stochastic sensors provide a reliable and highly sensitive method for glycogen detection in tissues.
- These sensors are valuable tools for assessing tissue aging and health status.
- The low limit of determination enables precise glycogen quantification even at trace levels.
