Digital microfluidic chip fabrication. (a) Overview of inkjet-printed DMF chips. (i) Two-plate DMF chips comprise a top plate of ITO-glass coated with a hydrophobic layer and a bottom plate of inkjet-printed silver on a flexible printing media which is mounted on a glass slide. (ii) Commercial inkjet printers can be adapted to print silver ink on flexible substrates. Reproduced from Ng et al., Sci. Trans. Med. 10(438), eaar6076 (2018).
