Summary: A novel chemiluminescence hydrogel is developed for rapid color visualization of sarcosine in urine, which can be used for information encryption and protection. Four different colors of chemiluminescence hydrogels are prepared by adding different ratios of rhodamine B or fluorescein. In the multicolor hydrogels, activated chemiluminescence can generate conventional multicolor code shift and original white light. The luminescence duration and cause of white light are analyzed using chemiluminescence spectroscopy. Sarcosine oxidase is replaced with sarcosine in the multicolor hydrogels to obtain the translation of editable code, facilitating secondary information encryption and code transmissions. The effective luminescence time of these hydrogels is short (13-50 min), and the code can be naturally deleted.
