The microfluidic device, patented under US Patent 10,123,456, is a sophisticated in vitro model designed to mimic the intricate functions of human organs for biomedical research purposes. This device consists of a polydimethylsiloxane (PDMS) substrate with a network of microchannels and chambers, fabricated using soft lithography techniques. The microfluidic channels are precisely designed to replicate the complex architecture of human organs, allowing for the coculture of multiple cell types in a controlled environment.The device features a modular design, comprising multiple organ modules, each representing a specific human organ, such as the liver, kidney, heart, and lungs. These modules are interconnected via a network of microfluidic channels, enabling the recirculation of culture media and the exchange of metabolites and signaling molecules between the different organ modules. The device is equipped with a proprietary membrane technology that allows for the diffusion of oxygen and nutrients while maintaining a stable pH and temperature.The microfluidic device is integrated with a range of sensors and actuators, including pressure sensors, flow sensors, and temperature sensors, which enable real-time monitoring and control of the device's performance. The device is also equipped with a user-friendly interface, allowing researchers to easily program and monitor the device's operation. The device's control system is based on a microcontroller, which regulates the flow of culture media, gas exchange, and temperature.The device has been extensively validated using a range of in vitro and in vivo models, demonstrating its ability to accurately replicate human organ functions and predict the pharmacokinetics and toxicology of various compounds. The device has significant potential for applications in biomedical research, including the development of novel therapeutics, toxicity testing, and personalized medicine. The patented technology has been licensed to several major pharmaceutical companies and research institutions, and is being used in a range of research applications, from basic scientific research to clinical trials.
