A flexible method for patterning colloidal particles, bubble-pen lithography (BPL) uses optically controlled microbubbles created by the laser heating of metal nanostructures. In comparison to the current manufacturing techniques for hierarchically-assembled layered materials, the use of BPL for guided assembly at the bubble interface would offer numerous benefits.
Inspired by preliminary research, I aim to comprehend how surface chemistry controls the hierarchical assembly of anisotropic nanoparticles at the bubble interface and use this understanding to design useful self-assembled materials with predetermined orientation from the nanoscale to the macroscale.
Chemically altering the edges and faces will enable orientational control over the assembly of particles at the bubble interface, enabling the formation of predictable configurations like end/end and side/side.
The application of BPL will also offer a more adaptable way to create hierarchical structures almost instantly and in a way that permits directed production of particular patterns on surfaces. Additionally, a direct path for the production of hollow structures will be made possible by the chemical cross-linking or polymerization of molecules coating the particles. Improved methods for the guided manufacturing of materials with applications in photonics.
The Global Laser bubble-pen lithography Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.

It takes dependable fabrication techniques with high resolution for downsizing, desirable components for improved performance, and high throughput for quick prototyping and large production to create on-chip functioning devices.
For sub-micron linewidths, in situ synthesis of bespoke materials, and on-demand patterning for diverse functional components and devices, laser-based bubble-pen lithography (BPL) has recently been developed. BPL uses Marangoni convection, which is brought on by a laser-controlled microbubble, to draw particles, ions, and molecules to various substrates and then collect and immobilize them there.
