High-throughput print-to-screen (P2S) platform for combinatorial chemotherapy

This paper reports a microfluidic enabled print-to-screen (P2S) platform, which can achieve low-cost, high-throughput, high-precision printing with plug-and-play disposable cartridge, as well as parallel screening with minimized crosstalk. The performance of the P2S platform is characterized and, using this platform, the cell-killing performance of 3-out-of-10 drug combinations towards ovarian cancer cell is, for the first time, studied and as a result, 15 out of 175 drug combinations are newly identified to exert potent cancer cell toxicity. This demonstrates the potent applicability of P2S platform for combinatorial chemotherapy, which can greatly speed up the entire cycle of drug cocktail discovery.
