摘要： Particles, such as cells, are isolated for conducting single-particle measurement. Isolation of rare cells, such as circulating tumor cells (CTCs), from blood is technically challenging because they are small in numbers. An integrated microfluidic biochip, dubbed as CTC chip, was designed and fabricated for conducting tumor cell isolation. As CTCs are usually multidrug resistance (MDR), the effect of MDR inhibitors on chemotherapeutic drug accumulation in the isolated single tumor cell is measured. In this invention, label-free isolation of the rare tumor cells was conducted based on cell size difference. The major advantages of the CTC chip are the ability of fast cell isolation, followed by multiple rounds of single-cell measurement, suggesting a potential assay for detecting the drug responses based on the liquid biopsy of cancer patients.

The cooling sheet includes a hot surface and a cooling surface. The thermal conductive base is located above the cooling surface of the cooling sheet, and configured to support electronic components on a printed circuit board and transfer heat between the electronic components and the cooling surface. When the cooling sheet is powered on, the cooling surface is in a constant state of low temperature. Due to the heat transfer between the cooling surface and the thermal conductive base, heat from the electronic components can be transferred from the thermal conductive base to the cooling surface continuously.
