(B) Magnetic ionic liquid (MIL) extraction of DNA. The MIL is recovered using a magnetic rod (B = 0.66 T). Reprinted with permission from Ref. 66. Copyright 2015, American Chemical Society. (C) Illustration of solid-phase microextraction (SPME) for RNA purification. Polyacrylate sorbent fibers are either coated with ionic liquid or cross-linked to dT oligos to enhance mRNA capture. The extraction was evaluated by reverse transcription quantitative polymerase chain reaction (RT-qPCR). Reprinted with permission from Ref. 73. Copyright 2017, American Chemical Society.
