What are the Challenges in Developing Gold Nanoparticle Based Sensors?
Despite their advantages, there are challenges in developing AuNP-based sensors:
Reproducibility - Ensuring consistent size and shape of AuNPs is crucial for reliable sensor performance. Functionalization - Attaching specific molecules to the surface of AuNPs can be complex and may affect their optical properties. Cost - Although gold is stable, it is also expensive, which can increase the cost of the sensors. Integration - Incorporating AuNP-based sensors into existing devices and systems can be challenging.
