The development of solid-phase microextraction fibers with metal wires as supporting substrates

•A review of novel SPME fibers with metal wires as supporting substrates.•Novel SPME fibers prepared by physical, chemical and electrochemical methods.•Lifetimes, desorption conditions and analytical performances of SPME fibers compared.•Novel SPME fibers applied in environmental, food, biological and medicinal analysis.

This article gives a brief overview of the most relevant examples of solid-phase microextraction (SPME) fibers with metal wires as substrates, mainly concerning different preparation strategies including physical coating, chemical bonding and some other preparation techniques, which involved various sorbent materials (e.g., polymers, nanomaterials, mesoporous materials, metal-organic frameworks, and ionic liquids).
