a Schematic diagram and experimental results of the cupramine complexation reaction. b Schematic diagram and photograph of the synthesis reaction of glycine and ninhydrin. c Schematic diagram and experimental results of simultaneous detection of metal ions: Fe3+ using the phenanthroline method, Al3+ using the chrome azure S method, and Cr6+ using the diphenylcarbazide method. d Schematic diagram and experimental results of simultaneous detection of biochemical indicators: protein (PR) detection using the biuret method, urea detection using a chromogenic kit, and pH detection using bromothymol blue. e Schematic illustration of nucleic acid detection using synthetic biosensors and glucose 6-phosphate dehydrogenase (G6PD) colorimetric reaction. f Results of four parallel nucleic acid detection tests in a droplet array containing solutions with different RNA concentrations (0, 0.25 nM, 5.00 nM, 100.00 nM). g Colorimetric analysis of each droplet in the droplet array. Data of distinct samples are presented as mean ± s.d., n = 4. The scale bars represent 1 cm.
