Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring coenzyme Q10 (CoQ10) and its reduced form, CoQ10H2, are not robust, accurate, or efficient, particularly in high-throughput screening, and are associated with various health issues such as mitochondrial cytopathies, diabetes, heart disease, and cancer, highlighting the need for improved extraction and detection techniques.
Innovation Solution
The development of methods involving the use of first and second extraction buffers that result in phase separation, followed by spectroscopic analysis, which enhances the detection of CoQ10, achieving a higher extraction efficiency compared to traditional methanol-only extraction methods, and the use of deuterated internal standards for precise quantification by mass spectrometry.

Engineering Contradiction Analysis
1Productivity
If traditional methanol-only extraction methods are used, then the extraction process is simple, but the extraction efficiency is low and detection sensitivity is insufficient
Solution Approach 1:
The extraction process is divided into two distinct phases: first extraction buffer (aqueous phase with detergent) and second extraction buffer (organic phase). This segmentation allows each buffer to perform its specific function optimally - the first buffer solubilizes cellular components and releases CoQ10, while the second buffer extracts CoQ10 from the aqueous phase, achieving 25-fold greater extraction efficiency compared to single-buffer methods
Solution Approach 2:
The first extraction buffer acts as an intermediary that facilitates the transfer of CoQ10 from the cellular matrix to the second extraction buffer. By using a detergent-containing aqueous buffer as an intermediate medium, the hydrophobic CoQ10 can be solubilized and then efficiently transferred to the organic phase, overcoming the limitation of direct methanol extraction
2Productivity
If rapid extraction methods are implemented, then high-throughput screening capability is improved, but measurement precision and accuracy may be compromised
Solution Approach 1:
The method optimizes multiple parameters simultaneously: extraction buffer composition (detergent concentration, buffer pH), extraction conditions (temperature, mixing time), and phase separation parameters. These parameter optimizations enable rapid extraction (completing in minutes) while maintaining high extraction efficiency and measurement accuracy through spectroscopic detection
Solution Approach 2:
The method replaces complex mechanical separation systems (such as centrifugation or filtration) with a simplified phase separation approach using immiscible buffers. The organic and aqueous phases naturally separate, allowing for rapid decanting or pipetting of the organic layer containing extracted CoQ10, thus enabling high-throughput processing without compromising precision
3Measurement precision
If CoQ10 detection sensitivity is increased, then diagnostic capability is improved, but the complexity of detection methods increases
Solution Approach 1:
The method extracts CoQ10 from the complex biological matrix into a clean organic phase using the two-buffer system. This extraction concentrates CoQ10 away from interfering substances (proteins, lipids, other cellular components), enabling sensitive and specific detection by spectroscopy without requiring complex sample preparation or cleanup steps
Solution Approach 2:
The method utilizes the inherent optical properties of CoQ10 (absorption spectrum characteristics) for direct spectroscopic detection. By extracting CoQ10 into the organic phase, the detection system can measure absorbance at specific wavelengths with high sensitivity, avoiding the need for complex labeling or derivatization procedures
