“…Furthermore, it was capable of integrating all the analytical stages commonly conducted in a laboratory, including sample pre-treatment, reagent transmission, mixing, reaction, separation, and determination [57,60,69,92]. There is an emerging tendency of constructing new analytical methods for use with 3D printing chip devices, such as, colorimetric method [78,[93][94][95][96], electrochemical (EC) method [22,73,97], chemiluminesce (CL) method [61,98], electrochemiluminescence (ECL) method [31,77], mass spectrometry (MS) analysis [59,67], and fluorescence method [70,92].…”
