What Are the Challenges in Stir Bar Selection for Nanotechnology?
Selecting the right stir bar for nanotechnology applications can be challenging due to the unique requirements of nanoscale reactions. Some of the challenges include:
1. Scaling Down: Traditional stir bars may not be effective in small-scale reactions typical in nanotechnology. Micro-sized stir bars might be necessary.
3. Contamination: Ensuring that the stir bar does not introduce any contaminants into the reaction is critical, especially for high-purity nanomaterials.
