Conclusion
This review summarizes the advances in using signaling molecules entrapped or assembled in nanomaterials for colorimetric and fluorescence immunoassays.
Supporting Evidence
- Nanolabels can produce detectable signals directly or release many signaling molecules for signal amplification.
- Nanomaterials have advantages over traditional enzymes, including lower cost and better stability.
- Self-assembly of signaling molecules can enhance detection sensitivity in immunoassays.
Takeaway
Scientists are using tiny materials called nanolabels to help detect diseases more easily and accurately in tests.
Methodology
The review discusses various types of nanomaterials, including liposomes, polymers, and metal-organic frameworks, and their applications in immunoassays.
Limitations
The review notes challenges in achieving high sensitivity, simplicity, stability, and repeatability in biosensors.
