Litho-particle Dispersions: Designer Particles with Customizable Shapes
- Technology Benefits
- High level of control over shapes, sizes, features, color and fluorescenceMassively parallel high throughput production of particlesComplex multi-layer 3D shapes and customizable internal compositionsAbility to tailor functional surface groups to control stability and interactions
- Technology Application
- Microscale LithoParticles, whose fluorescence and desired shape can be customized, can function as anti-counterfeit security inks to authenticate highly valuable documents or items. They could also serve as novel fluorescent probes for biological applications such as biological and molecular tagging and cell imaging.
- Detailed Technology Description
- The invention described here uses directed, top-down processes facilitated by automated lithography, for rapid, massively parallel, high throughput production of particles of customizable shapes that exhibit high fidelity and uniformity. As a demonstration of the power of this invention, UCLA researchers have designed and fabricated colloidal alphabet soup: a dispersion of microscale polymer particles representing all twenty-six letters of the English alphabet in a viscous liquid. Submicron and nanoscale particles can be created by the same processes as well. Moreover, the internal composition, color, fluorescence, and 3-D structures of the particles can all be customized.

Background
Bottom-up synthesis can produce a very limited variety of particle shapes, such as spheres and rods, in a viscous liquid. The resulting particles can be highly uniform in size. However, there is no general method for mass-producing a wide variety of highly complex shapes that are specified by a customer using bottom-up self-assembly approaches. Although uniform microspheres have been used extensively in many protocols, these applications can be enhanced by using particles that have customized, user-specified shapes. Mass-producing particle shapes that conform with a desired design would revolutionize the variety of dispersions that are commercially available.

- *Abstract
-
UCLA Researchers in the Department of Chemistry and Biochemistry and Department of Physics and Astronomy have developed and reduced to practice processes for mass-producing microscale and nanoscale particles with customizable control over particle shapes, compositions, and features. LithoParticle dispersions are ideal for biomarker applications in biological tagging and imaging, for anti-counterfeit security, and as parts for creating complex assemblies in solution.
- *Applications
-
Microscale LithoParticles, whose fluorescence and desired shape can be customized, can function as anti-counterfeit security inks to authenticate highly valuable documents or items. They could also serve as novel fluorescent probes for biological applications such as biological and molecular tagging and cell imaging.
