β High precision and control.
Detailed Explanation
Dip-Pen Nanolithography (DPN) offers exceptional precision by using an atomic force microscope (AFM) tip that acts like a pen. This allows for incredibly fine control over where molecules are deposited on a surface, down to the nanoscale. The setup enables the scientist or technician to draw very small patterns with great accuracy.
Examples & Analogies
Think of painting a tiny detail on a model. Using a fine brush allows you to create intricate designs that would be impossible with a larger brush. Similarly, DPNβs use of a tiny AFM tip permits the deposition of molecular 'ink' in precise locations.
