Scope and Objectives

1. Develop technology and machines for manufacturing 2.5 dimensional multiscale ordered fractal structures, with robust control over otherwise spontaneous evolution, and further retaining them for use in applications. 2. Develop mathematical model, and further, experimentally characterize family of materials and process parameters leading to identification of range of structures and degree of control. 3. Develop software to correlate desired fractal geometry structure and machine parameters. 4. Fabricate prototype components in the machine for pumpless blood plasma, cell separation on chip, and capillary pumping. The components will be developed closely with industrial partner, to be integrated in their products.

Deliverables

Main deliverable of project is the machine and technology for fabrication of multiscale fractal structures. The machine would be capable of fabrications to the specifications mentioned earlier,spanning multiple scales. The software will be delivered along with the machine. The software would specify the Hele-Shaw cell preparations to be done for a desired geometry and for a specific application. As a part of the machine, technology for high precision large range travel using dual actuators would be developed. Along with the machine we will demonstrate two application deliverables: 1. Capillary based micropumps for point of care devices 2. Platforms for chemotaxis based on the proposed process. In addition several other applications as mentioned in Section 7 point 9 would be explored towards their commercial potential. Some important other outcomes of the process are highlighted below:1. The availability of process, machine, and knowhow, and the fact that natural systems are shaped in fractal geometry, would stimulate research into application this field (in domains mentioned and even other domains not mentioned) not only internationally but at the national level as well (since affordable methods of microfabrication at multiple scales would be easily available)2. The research may further create demand and market for the technology. 3. The proposed idea builds and would further stimulate research in the direction of development of machines and technologies effective at multiple scales of operation.

Results and outcome till date

Development and fabrication of machine for large area micromilling (required for anisotropy creation in the process, status: being installed), small micromilling machine. Development and fabrication of machines (several ve rsions with different sizes and level of automation) to carry out the proposed process of fabrication of array and fractal geometry patterns. Part of the software for simulaton of process with multiple holes using Voronoi diagrams: This is to simulate patterns we would get for given set of anisotropies and plan the desired patterns. Development and process characterization for several materials that would give the desired patterns for several applications. (example sintered ceramic structures, silver ink structures, PLGA, PSS, and so on) Development and testing of devices for several applications: - Capillary pumps : Fractal channel device for point of care devices - Drug screening device - Device for bio-assay without need for plasma separation Fundamental studies and explorations - Innovative other way of using lands as anisotropies - Spontaneous fabrication in 3rd dimension

Societal benefit and impact anticipated

Fabricated multiscale structures are useful for several application in bio-medical field including commercially viable devices for organ-on-chip, plasma separation, drug screening, chemotaxis, capillary pumps, microfluidic mixers, and so on. Multiscale structure fabrication techniques establishes solid foundation for biomimicking natural structures. Branched structures are also useful in non-transparent solar electrodes, heat exchangers, mass transporters and vascular systems. Lithography less process reduces the cost of a final device made up using multiscale structure.

Next steps

We would like to collaborate with additional companies/ research labs partners who would like to use the technology and machines for their own applications.
