Objective: To achieve an effective directed assembly and transfer process using flat substrates (without trench structure).
Approach: Functionalized flexible flat templates were used for directed assembly of nanoparticles. These templates elastic properties ensure a more effective nano transfer process. The template has hydrophobic/hydrophilic patterns for the convective directed assembly.
Broader Impact: These processes can be applied to a continuous or reel-to-reel nano-manufacturing process. This will also make it possible to manufacture many devices such as optical devices, chemical sensors, high-density data-storage, plastic electronics, and biology applications.
Significant Results: We are successfully assembled on flat substrates and dry-transferred nano-particles to silicon wafers.
