The construction of ofloxacin detection in fish matrix based on a shark-derived single-domain antibody.

Background: Due to the serious issue of ofloxacin (OFL) abuse, there is an increasingly urgent need for accurate and rapid detection of OFL. Immunoassay has become the "golden method" for detecting OFL in complex matrix beneficial to its applicability for a large-scale screening, rapidity, and simplicity. However, traditional antibodies used in immunoassay present challenges such as time-consuming preparation, unstable sensitivity and specificity, and difficulty in directional evolution.

Multifunctional metal-organic framework-enhanced sodium alginate-based intelligent indicator: Mechanism and application for freshness monitoring.

Intelligent food packaging has recently gained significant attention due to the heightened consumer awareness regarding food quality. Although anthocyanins avoid safety issues, the instability and leakage of anthocyanins restrict their utilization in freshness indicator labels. In this study, we introduced an innovative metal-organic framework (UiO-66-NH) synergistic pH-colorimetric label with fast ammonia-responsive, incorporating sodium alginate, red cabbage anthocyanin, and UiO-66-NH.
