摘要：

Microfluidic paper-based analytical devices ( PADs) have a significant potential in developing portable and disposable point-of-care testing (POCT). Herein, a facile, rapid, cost-effective and environment friendly strategy for PADs fabrication is proposed. Specifically, the substrate paper was hydrophobized by coating with trimethoxysilane (TOS), and then the selected area was hydrophilized by treating with surfactant. The whole fabrication process was implemented within 7 min, with no need for complex pretreatment, high-temperature and special equipment. As a proof-of-concept application, the as-prepared PAD was applied to determination of the glucose content in human serum samples. The results agreed well with those obtained by a glucometer. We believe that the pPADs fabrication method proposed here could provide a facile, rapid and low-cost reference for other related studies. (C) 2017 Elsevier Inc. All rights reserved.
