Tumor Microarray Overview
Microfluidic tumor microarrays are microchip systems that mimic the human tumor microenvironment.
It simulates the process of tumor growth by controlling the flow of fluids and cells within the chip through microfluidics, and allows real-time monitoring and analysis of tumor cell growth, migration, invasiveness, and drug response.
Microfluidic tumor microarrays can provide more accurate, efficient and reproducible experimental models for tumor research and treatment.
Key benefits of microfluidic tumor microarrays include:
- The microenvironment of tumor growth can be simulated, including interactions between tumor cells and the extracellular matrix, cell-cell interactions, and cell-drug interactions.
- Tumor cell growth, migration, invasiveness and drug response can be monitored and analyzed in real time, and these biological characteristics can be quantified.
- High-throughput tumor drug screening and prediction can be performed, thus improving the efficiency and success of drug development.
Applications of microfluidic tumor microarrays include tumor biology research, tumor drug screening and clinical treatment. With the continuous development and improvement of microfluidic chip technology, it is believed that microfluidic tumor chip will become one of the important tools in the field of tumor research and treatment.
