Convective Assembly and Transfer Using Flexible Templates

Convective Assembly and Transfer Using Flexible Templates

| June 4, 2013

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 […]
