- Abstract
- Microfluidic drug screening technologies have been extensively explored to evaluate the pharmacology and therapeutic implications of promising chemical compounds in multiplexed physiological microenvironments in vivo. However, conventional poly(dimethylsiloxane) microchips are susceptible to adsorption by hydrophobic molecules on channel surfaces and permeation in the matrix. These can significantly compromise the drug availability and accuracy of dose-dependent quantitative analyses. Here, we prepared a perfluorinated polyether (PFPE) microchip via digital light processing 3D printing as a quantitative drug screening platform for precise concentration-dependent pharmaceutical assays. Cells cultured on PFPE microchips exhibited excellent viability with a spread morphology as well as superior proliferative capability. Importantly, PFPE constructions with a low surface energy significantly prevented the nonspecific molecular adsorption into their surfaces or permeation into the matrix. In particular, the PFPE multibranched channel preserved the concentration of the pharmaceutical drug during the perfusion process and generated a linear concentration gradient, resulting in a dose-dependent chemotherapeutic effect. We suggest that the biocompatible and nonadsorbing PFPE microchannel can provide a cell-based drug screening platform for concentration-dependent quantitative analyses.
