Multicolor saccharide-sensing chips based on boronic acid-containing thin films

新型糖类传感芯片被开发出来，可以显示出明显的颜色变化。利用含硼酸的聚阳离子，通过逐层的方法在图案印刷显微镜玻片上获得了糖响应薄膜。吸附阴离子染料后，将薄膜浸泡在糖水溶液中。随着糖浓度的增加，薄膜呈现出多图案的颜色变化，这使得利用多比色传感来定量糖成为可能。

Novel saccharide-sensing chips that show distinct color changes were developed. The saccharide-responsive thin films were obtained on a pattern-printed microscope slide via a layer-by-layer method utilizing a boronic acid-containing polycation. After adsorption of anionic dyes, the thin films were immersed in aqueous saccharide solutions. As the saccharide concentration increased, the thin films showed a multi-patterned color change that enabled the quantification of saccharides using multi-colorimetric sensing.
