Highly efficient zinc finger peptide detection with ZIF-8-modified micropipets.

Zeolitic imidazolate framework-8 (ZIF-8)-modified micropipets can be an effective sensing platform for zinc finger peptides, the limit of detection of which reaches 10-2 μg ml-1. A series of techniques for detecting biomolecules are expected to emerge because of its simplicity, low cost, and universality by modifying other functional materials into the micropipets.
