The invention replaces complex mechanical and chemical analysis systems with an electrochemical sensing system. Instead of using traditional chromatography or spectrometry equipment, the patent uses electrochemical reactions at microelectrodes to detect Clozapine, dramatically reducing equipment complexity and detection time.
2Reliability
If conventional detection equipment is used, then reliable detection is achieved, but equipment cost and technical expertise requirements increase
Solution Approach 1:
The patent merges multiple functions into a single integrated microfluidic cartridge: sample introduction, mixing, reaction, and detection all occur within one compact device. This consolidation maintains reliable detection while eliminating the need for complex external equipment and reducing technical expertise requirements.
Solution Approach 2:
The microfluidic sensing platform is designed with universal applicability for detecting various analytes including Clozapine, dopamine, and other substances. This multi-functionality is achieved through modular electrode configurations and flexible microfluidic channel designs that can accommodate different detection requirements without requiring separate specialized equipment.
3Productivity
