Polyamide/titania hollow nanofibers prepared by core–shell electrospinning as a microextractive phase in a fabricated sandwiched format microfluidic device

摘要

Highlights?Core–shell polyamide/titania hollow nanofibers were synthesized using electrospinning.?A low–cost microfluidic device was fabricated by laser engraving technique.?The device is consisted of a central chip unit with an aligned microchannel.?The microfluidic device in a sandwiched format is used to hold the nanofibers sheets.?The setup was ultimately employed for the ultra–trace analysis of some model herbicides.AbstractIn this study, a low–cost microfluidic device from polymethyl methacrylate was fabricated by laser engraving technique. The device is consisted of a central chip unit with an aligned microchannel. Both sides of the engraved microchannel were sandwiched by two synthesized sheets from polyamide/titania (PA/TiO2) hollow nanofibers as extracti
